ucwords

(PHP 4, PHP 5, PHP 7, PHP 8)

ucwords — Converte para maiúsculas o primeiro caractere de cada palavra

Descrição

ucwords(string $string, string $separators = " \t\r\n\f\v"): string

Retorna uma string com o primeiro caractere de cada palavra em string em maiúscula, se este caractere for uma letra ASCII entre "a" (0x61) e "z" (0x7a).

Nesta função, uma palavra é qualquer sequência de caracteres não listada no parâmetro separators. Por padrão, os separadores são: espaço, tab horizontal, retorno de carro, nova linha, form feed e tab vertical.

Para realizar uma conversão similar em strings multibyte, utilize mb_convert_case() com a opção MB_CASE_TITLE.

Parâmetros

string: A string de entrada.
separators: O parâmetro opcional separators contém os caracteres separadores das palavras.

Valor Retornado

Retorna a string modificada.

Registro de Alterações

Versão	Descrição
8.2.0	A conversão de maiúsculas e minúsculas não depende mais da localidade definida com setlocale(). Somente caracteres ASCII serão convertidos.

Exemplos

Exemplo #1 Exemplo da ucwords()

<?php
$foo = 'hello world!';
$foo = ucwords($foo);             // Hello World!

$bar = 'HELLO WORLD!';
$bar = ucwords($bar);             // HELLO WORLD!
$bar = ucwords(strtolower($bar)); // Hello World!
?>

Exemplo #2 Exemplo de ucwords() com delimitador

<?php
$foo = 'hello|world!';
$bar = ucwords($foo);             // Hello|world!

$baz = ucwords($foo, "|");        // Hello|World!
?>

Exemplo #3 Exemplo de ucwords() com delimitadores adicionais

<?php
$foo = "mike o'hara";
$bar = ucwords($foo);                 // Mike O'hara

$baz = ucwords($foo, " \t\r\n\f\v'"); // Mike O'Hara
?>

         * Exceptions all in upper case are any words you don't want converted to title case
         *   but should be converted to upper case, e.g.:
         *   king henry viii or king henry Viii should be King Henry VIII
         */
        $string = mb_convert_case($string, MB_CASE_TITLE, "UTF-8");
        foreach ($delimiters as $dlnr => $delimiter) {
            $words = explode($delimiter, $string);

                } elseif (!in_array($word, $exceptions)) {
                    // convert to uppercase (non-utf8 only)
                    $word = ucfirst($word);
                }
                array_push($newwords, $word);

            $string = join($delimiter, $newwords);
       }//foreach
       return $string;

My quick and dirty ucname (Upper Case Name) function.

<?php
//FUNCTION

function ucname($string) {
    $string =ucwords(strtolower($string));

    foreach (array('-', '\'') as $delimiter) {
      if (strpos($string, $delimiter)!==false) {
        $string =implode($delimiter, array_map('ucfirst', explode($delimiter, $string)));
      }
    }
    return $string;
}
?>
<?php
//TEST

$names =array(
  'JEAN-LUC PICARD',
  'MILES O\'BRIEN',
  'WILLIAM RIKER',
  'geordi la forge',
  'bEvErly CRuSHeR'
);
foreach ($names as $name) { print ucname("{$name}\n"); }

//PRINTS:
/*
Jean-Luc Picard
Miles O'Brien
William Riker
Geordi La Forge
Beverly Crusher
*/
?>

You can add more delimiters in the for-each loop array if you want to handle more characters.

Based on code sample originally posted by "Anonymous" on 2005-12-14. The /e modifier is no longer supported by preg_replace(). Rewritten to use preg_replace_callback() instead. Tested with PHP 7.3.

The function below will standardize the capitalization on people's names, addresses, and the titles of reports and essays . Adapt the lists in "$all_uppercase" and "$all_lowercase" to suit the data that you are working with.

function ucwords_title($string, $is_name = false) {
    // Exceptions to standard case conversion
    if ($is_name) {
        $all_uppercase = '';
        $all_lowercase = 'De La|De Las|Der|Van De|Van Der|Vit De|Von|Or|And';
    } else {
        // Addresses, essay titles ... and anything else
        $all_uppercase = 'Us|Ca|Mx|Po|Rr|Se|Sw|Ne|Nw';
        $all_lowercase = 'A|And|As|By|In|Of|Or|To';
    }
    $prefixes = 'Mac|Mc';
    $suffixes = "'S";

    // Trim whitespace and convert to lowercase
    $str = strtolower(trim($string));

    // Capitalize all first letters
    $str = preg_replace_callback('/\\b(\\w)/', function ($m) {
        return strtoupper($m[1]);
    }, $str);

    if ($all_uppercase) {
        // Capitalize acronyms and initialisms (e.g. PHP)
        $str = preg_replace_callback('/\\b(' . $all_uppercase . ')\\b/', function ($m) {
            return strtoupper($m[1]);
        }, $str);
    }
    if ($all_lowercase) {
        // Decapitalize short words (e.g. and)
        if ($is_name) {
            // All occurrences will be changed to lowercase
            $str = preg_replace_callback('/\\b(' . $all_lowercase . ')\\b/', function ($m) {
                return strtolower($m[1]);
            }, $str);
        } else {
            // First and last word will not be changed to lower case (i.e. titles)
            $str = preg_replace_callback('/(?<=\\W)(' . $all_lowercase . ')(?=\\W)/', function ($m) {
                return strtolower($m[1]);
            }, $str);
        }
    }
    if ($prefixes) {
        // Capitalize letter after certain name prefixes (e.g 'Mc')
        $str = preg_replace_callback('/\\b(' . $prefixes . ')(\\w)/', function ($m) {
            return $m[1] . strtoupper($m[2]);
        }, $str);
    }
    if ($suffixes) {
        // Decapitalize certain word suffixes (e.g. 's)
        $str = preg_replace_callback('/(\\w)(' . $suffixes . ')\\b/', function ($m) {
            return $m[1] . strtolower($m[2]);
        }, $str);
    }

    return $str;
}

// A name example
print ucwords_title("MARIE-LOU VAN DER PLANCK-ST.JOHN", true);
// Output: Marie-Lou van der Planc-St.John

// A title example
print ucwords_title("to be or not to be");
// Output: "To Be or Not to Be"

Some recipes for switching between underscore and camelcase naming:



<?php

// underscored to upper-camelcase

// e.g. "this_method_name" -> "ThisMethodName"

preg_replace('/(?:^|_)(.?)/e',"strtoupper('$1')",$string);



// underscored to lower-camelcase

// e.g. "this_method_name" -> "thisMethodName"

preg_replace('/_(.?)/e',"strtoupper('$1')",$string);



// camelcase (lower or upper) to underscored

// e.g. "thisMethodName" -> "this_method_name"

// e.g. "ThisMethodName" -> "this_method_name"

strtolower(preg_replace('/([^A-Z])([A-Z])/', "$1_$2", $string));

?>



Of course these aren't 100% symmetric.  For example...

  * this_is_a_string -> ThisIsAString -> this_is_astring

  * GetURLForString -> get_urlfor_string -> GetUrlforString

In the function ucsmart() posted by ieure at php dot net on 04-Dec-2005 11:57, I found a similar problem in this function to what he found in igua's.

<?php
function ucsmart($text)
{
   return preg_replace('/([^a-z]|^)([a-z])/e', '"$1".strtoupper("$2")',
                       strtolower($text));
}
?>

"igua's code adds a backslash in front of the first single quote for me. This doesn't alter the content in any way other than changing case."

Actually, it did end up changing the content for me (php 5.0.4) in the way that this function escapes a single quotation (apostrophe) in the MIDDLE of a word.

For example:

who's online?

Became:

Who\'s Online?

The fix is simple however, and merely requires fine-tuning the regular expression:

<?php
function ucsmart($text)
{
   return preg_replace('/([^a-z\']|^)([a-z])/e', '"$1".strtoupper("$2")',
                       strtolower($text));
}
?>

(note: while previewing this note before adding it, I am noticing php's website is not correctly displaying the change I made as I wrote it. After the first a-z in the expression, the single quotation should be escaped... If it isn't you will get a parse error! And apoligies if my text here is colored as php code; not my fault!)

This will not escape a single quotation mark which occurs in the middle of a word... Though, you may find that might need to add other characters inside the regular expression if you use other special characters inside your words and if you get funky output.

It's a great expression though! Simple, yet very powerful. Kudos!

Here is a function to capitalize a last name, accounting for hyphens, apostrophes, "Mc" and "Mac":

<?php
function CapitalizeLastName($name) {
    $name = strtolower($name);
    $name = join("'", array_map('ucwords', explode("'", $name)));
    $name = join("-", array_map('ucwords', explode("-", $name)));
    $name = join("Mac", array_map('ucwords', explode("Mac", $name)));
    $name = join("Mc", array_map('ucwords', explode("Mc", $name)));
    return $name;
}
?>

I speed tested it against functions that used preg_replace() with an "e" modifier, preg_replace_callback(), and a character-by-character parsing.  Unexpectedly, this function using join(), array_map() and explode() was fastest.

Relating to the mb_ucwords() function posted by Anonymous.  In order for this to actually be multi-byte compliant, you would also need to use mb_substr() and mb_strlen() instead of substr and strlen respectively.

Here it is corrected and extended even further to allow multiple word separators and a list of exceptions to correct after title casing. It's a bit tedious and inelegant, but things frequently are when dealing with human languages.

function mb_ucwords($str) {
    $exceptions = array();
    $exceptions['Hp'] = 'HP';
    $exceptions['Ibm'] = 'IBM';
    $exceptions['Gb'] = 'GB';
    $exceptions['Mb'] = 'MB';
    $exceptions['Cd'] = 'CD';
    $exceptions['Dvd'] = 'DVD';
    $exceptions['Usb'] = 'USB';
    $exceptions['Mm'] = 'mm';
    $exceptions['Cm'] = 'cm';
    //    etc.
    
    $separator = array(" ","-","+");
    
    $str = mb_strtolower(trim($str));
    foreach($separator as $s){
        $word = explode($s, $str);

        $return = "";
        foreach ($word as $val){
            $return .= $s . mb_strtoupper($val{0}) . mb_substr($val,1,mb_strlen($val)-1);
        }
        $str = mb_substr($return, 1);
    }

    foreach($exceptions as $find=>$replace){
        if (mb_strpos($return, $find) !== false){
            $return = str_replace($find, $replace, $return);
        }
    }
    return mb_substr($return, 1);

Params:

1. string: The string being converted

2. delimiters: a string with all wanted delimiters written one after the other e.g. "-'"

3. encoding: Is the character encoding. If it is omitted, the internal character encoding value will be used.



Example Usage:

<?php

mb_internal_encoding('UTF-8');

$string = "JEAN-PAUL d'artagnan şŠ-òÀ-éÌ hello - world";

echo ucwords_specific( mb_strtolower($string, 'UTF-8'), "-'");

Q1712 at online dot ms ¶

ucwords() only excepts whitespace in front of a word, although some chars like '"' or '(' normally have no space between them and the following word:
<?php
$title = 'ELVIS "THE KING" PRESLEY - (LET ME BE YOUR) TEDDY BEAR';
echo ucwords(strtolower($title));
?>
prints: Elvis "the King" Presley - (let Me Be Your) Teddy Bear

To avoid this i use a small function adding and deleting blanks behind these chars, and using ucwords() in between:

<?php
function my_ucwords($string)
  { 
    $noletters='"([/'; //add more if u need to
    for($i=0; $i<strlen($noletters); $i++)
      $string = str_replace($noletters[$i], $noletters[$i].' ', $string);
    $string=ucwords($string);
    for($i=0; $i<strlen($noletters); $i++)
      $string = str_replace($noletters[$i].' ', $noletters[$i], $string);
    return $string;
  }

$title = 'ELVIS "THE KING" PRESLEY - (LET ME BE YOUR) TEDDY BEAR';
echo my_ucwords(strtolower($title));
?>

prints: Elvis "The King" Presley - (Let Me Be Your) Teddy Bear

This seems to be what people want:



function uc_all($string) {

    $temp = preg_split('/(\W)/', $string, -1, PREG_SPLIT_DELIM_CAPTURE );

    foreach ($temp as $key=>$word) {

        $temp[$key] = ucfirst(strtolower($word));

    }

    return join ('', $temp);

}

"ieure at php dot net", your idea is pure poetry!

The function below will standardize the capitalization on people's names and the titles of reports and essays . You may need to adapt the lists in "$all_uppercase" and "$all_lowercase" to suit the data that you are working with.

function my_ucwords($str, $is_name=false) {
   // exceptions to standard case conversion
   if ($is_name) {
       $all_uppercase = '';
       $all_lowercase = 'De La|De Las|Der|Van De|Van Der|Vit De|Von|Or|And';
   } else {
       // addresses, essay titles ... and anything else
       $all_uppercase = 'Po|Rr|Se|Sw|Ne|Nw';
       $all_lowercase = 'A|And|As|By|In|Of|Or|To';
   }
   $prefixes = 'Mc';
   $suffixes = "'S";

   // captialize all first letters
   $str = preg_replace('/\\b(\\w)/e', 'strtoupper("$1")', strtolower(trim($str)));

A very easy way to convert to title case:

function titleCase($string)
     {
     return ucwords(strtolower($string));
     }

$myString = "SOME TEXT";

echo titleCase($myString);

//will print, "My Text"

A proper Turkish solution;



<?php

function ucfirst_turkish($str) {

    $tmp = preg_split("//u", $str, 2, PREG_SPLIT_NO_EMPTY);

    return mb_convert_case(

        str_replace("i", "İ", $tmp[0]), MB_CASE_TITLE, "UTF-8").

        $tmp[1];

}



function ucwords_turkish($str) {

    return preg_replace("/(\\w+)/ue", "ucfirst_turkish('\\\\1').'$2'", $str);

}



$str = "iyilik güzelLİK şeker ";

echo ucwords($str) ."\\n";   // Iyilik GüzelLİK şeker 

echo ucwords_turkish($str); // İyilik GüzelLİK Şeker

Thanks a lot brother.

I tested it with a few variations. It works perfectly. Its really great and simple usage of the existing functions. It would be glad to all PHP folks and good to PHP if these kind of functions will be in PHP library on upcoming releases.

<?php 

$name1 = "mark-yves robert";
$name2 = "mark-yves robert-bryan";

echo '<br/>Name 1 (mark-yves robert) =>'.
ucwordspecific($name1,'-'); //returns Mark-Yves Robert

echo '<br/>Name 2 (mark-yves robert-bryan) 

=>'.ucwordspecific($name2,'-'); 
//returns Mark-Yves Robert-Bryan

function ucwordspecific($str,$delimiter){
$delimiter_space = '- ';
return str_replace($delimiter_space,$delimiter,ucwords

(str_replace($delimiter,$delimiter_space,$str)));
}

?>

Proud to be a PHP enthusiast always :-)

I did the same thing as Catalin, but for French names.



Here's what I'm doing :



For each word (not considering the single-quote as a word boundary character) :

- Put the word in lower case

- If the word is "de", return, else, put the first letter in upper-case

- See if the second character of the word is a single-quote

- Yes ? Put the next char in upper case

- And if the char before the single quote is D, put it back to lower case (-> d)



This complies with the French rules for capitalization in names.



Sample results :

-d'Afoo Bar

-de Foo Bar

-O'Foo Bar

-Foo'bar



<?php

function my_ucwords($s) {

        $s = preg_replace_callback("/(\b[\w|']+\b)/s", fixcase_callback, $s);

        

        return $s;         

        

    }

    

    function fixcase_callback($word) {



        $word = $word[1];

        

        $word = strtolower($word);

        

        if($word == "de")

            return $word;

        

        $word = ucfirst($word);

        

        if(substr($word,1,1) == "'") {

            if(substr($word,0,1) == "D") {

                $word = strtolower($word);

            }

            $next = substr($word,2,1);

            $next = strtoupper($next);

            $word = substr_replace($word, $next, 2, 1);

        }

        

        return $word;

    }

Response to arif:

We do not need that long functions. In order to make ucwords() worked properly in Turkish words that contain speacial characters, we can use the following command in our php codes:

setlocale(LC_ALL, 'tr_TR');

This will set locale to Turkish.

The code posted above by Joerg Krause only works for a string which ends with one of the delimiters. A possible fix is:



<?php

$text = "What?No delimiters,shit happens here.this solves all problems."; 

preg_match_all("/(\w+[,. ?])+/U", $text, $words); 

preg_match("/(\w+)$/", $text, $lastword);

$words[0][] = $lastword;

foreach($words[0] as $part) $uwords[] = ucfirst($part); 

$text = implode("", $uwords); 

echo $text;

?>

to convert first letters in a firstname like: "jean-pierre" to "Jean-Pierre":

I simply replace the '-' with a vertical tabulation, because the ucwords() function replace the letter just after it.

so, I use the sentence:
$result=str_replace(chr(11),'-',ucwords(strtolower(str_replace('-',chr(11),$firstname))));

This will correct capitalisation in names taking note of special capitalisation for Mc..., Mac..., and O'... Other special cases, of which I am not aware, can be added easily.

This is just a slight improvement on "deepdene at email dot com"'s name_case function... Thank you for original function.

<?php

function name_case($name) {
    if( !$name ) return $name;
    $newname = strtoupper($name[0]);
    $break = false;
    for( $i=1; $i<strlen($name); ++$i ) {
      $subed = substr($name, $i, 1);
      if( ord($subed) > 64 && ord($subed) < 123 || ord($subed) > 48 && ord($subed) < 58 ) {
        if( $break ) {
          $newname .= strtoupper($subed);
        }
        elseif( $i > 1 && in_array(substr($newname, $i-2, 2), array('Mc', 'O\'')) || $i > 2 && in_array(substr($newname, $i-3, 3), array('Mac')) ) {
          $newname .= strtoupper($subed); 
        }
        else {
          $newname .= strtolower($subed);
        }
        $break = false;

      else {
        // not a letter - a boundary
