PHP 5.5.15 is released

copy

(PHP 4, PHP 5)

copyKopiert eine Datei

Beschreibung

bool copy ( string $source , string $dest [, resource $context ] )

Kopiert Datei source nach dest.

Wenn sie eine Datei verschieben möchten, nutzen sie die rename() Funktion.

Parameter-Liste

source

Pfad zu der Quelldatei.

dest

Der Zielpfad. Wenn dest ein URL ist, kann der Kopiervorgang fehlschlagen, wenn der Wrapper nicht das Überschreiben existierender Dateien unterstützt.

Warnung

Wenn die Zieldatei schon existiert, wird sie überschrieben.

context

Eine gültige Context Ressource, die mit stream_context_create() erzeugt wurde.

Rückgabewerte

Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.

Changelog

Version Beschreibung
5.3.0 Context Ünterstützung wurde hinzugefügt.
4.3.0 Sowohl source als auch dest können nun URLs sein, wenn die "fopen wrappers" aktiviert wurden. Siehe fopen() für weitere Einzelheiten.

Beispiele

Beispiel #1 copy() Beispiel

<?php
$file 
'example.txt';
$newfile 'example.txt.bak';

if (!
copy($file$newfile)) {
    echo 
"copy $file schlug fehl...\n";
}
?>

Having spent hours tacking down a copy() error: Permission denied , (and duly worrying about chmod on winXP) , its worth pointing out that the 'destination' needs to contain the actual file name ! --- NOT just the path to the folder you wish to copy into.......
DOH !
hope this saves somebody hours of fruitless debugging

It take me a long time to find out what the problem is when i've got an error on copy(). It DOESN'T create any directories. It only copies to existing path. So create directories before. Hope i'll help,

Don't forget; you can use copy on remote files, rather than doing messy fopen stuff.  e.g.

<?php
if(!@copy('http://someserver.com/somefile.zip','./somefile.zip'))
{
   
$errors= error_get_last();
    echo
"COPY ERROR: ".$errors['type'];
    echo
"<br />\n".$errors['message'];
} else {
    echo
"File copied from remote!";
}
?>

Thanks for all the comments, i wrote this function for fully supporting file and directory copy.
As you may have noticed there are feature that didn't have time to implement , but if you have time to implement them or even add more cool features, please notify me as well :). you can find me here http://sina.salek.ws/en/contact

PS : It was very useful for me, hope you find it useful as well.

/**
     * Copy file or folder from source to destination, it can do
     * recursive copy as well and is very smart
     * It recursively creates the dest file or directory path if there weren't exists
     * Situtaions :
     * - Src:/home/test/file.txt ,Dst:/home/test/b ,Result:/home/test/b -> If source was file copy file.txt name with b as name to destination
     * - Src:/home/test/file.txt ,Dst:/home/test/b/ ,Result:/home/test/b/file.txt -> If source was file Creates b directory if does not exsits and copy file.txt into it
     * - Src:/home/test ,Dst:/home/ ,Result:/home/test/** -> If source was directory copy test directory and all of its content into dest     
     * - Src:/home/test/ ,Dst:/home/ ,Result:/home/**-> if source was direcotry copy its content to dest
     * - Src:/home/test ,Dst:/home/test2 ,Result:/home/test2/** -> if source was directoy copy it and its content to dest with test2 as name
     * - Src:/home/test/ ,Dst:/home/test2 ,Result:->/home/test2/** if source was directoy copy it and its content to dest with test2 as name
     * @todo
     *     - Should have rollback technique so it can undo the copy when it wasn't successful
     *  - Auto destination technique should be possible to turn off
     *  - Supporting callback function

When I recently had to copy a few millions of small files (< 1kb) from one NAS to another and for some reasons had to do that file by file I compared the following function with copy($src, $dest) and shell_exec("cp -r $src $dest").

Surprisingly stream_copy seamed to be slightly faster (at least in this specific context).

<?php
   
function stream_copy($src, $dest)
    {
       
$fsrc = fopen($src,'r');
       
$fdest = fopen($dest,'w+');
       
$len = stream_copy_to_stream($fsrc,$fdest);
       
fclose($fsrc);
       
fclose($fdest);
        return
$len;
    }

Here is a simple script that I use for removing and copying non-empty directories. Very useful when you are not sure what is the type of a file.

I am using these for managing folders and zip archives for my website plugins.

<?php

// removes files and non-empty directories
function rrmdir($dir) {
  if (
is_dir($dir)) {
   
$files = scandir($dir);
    foreach (
$files as $file)
    if (
$file != "." && $file != "..") rrmdir("$dir/$file");
   
rmdir($dir);
  }
  else if (
file_exists($dir)) unlink($dir);
}

// copies files and non-empty directories
function rcopy($src, $dst) {
  if (
file_exists($dst)) rrmdir($dst);
  if (
is_dir($src)) {
   
mkdir($dst);
   
$files = scandir($src);
    foreach (
$files as $file)
    if (
$file != "." && $file != "..") rcopy("$src/$file", "$dst/$file");
  }
  else if (
file_exists($src)) copy($src, $dst);
}
?>

Cheers!

Here's a simple recursive function to copy entire directories

Note to do your own check to make sure the directory exists that you first call it on.

<?php
function recurse_copy($src,$dst) {
   
$dir = opendir($src);
    @
mkdir($dst);
    while(
false !== ( $file = readdir($dir)) ) {
        if ((
$file != '.' ) && ( $file != '..' )) {
            if (
is_dir($src . '/' . $file) ) {
               
recurse_copy($src . '/' . $file,$dst . '/' . $file);
            }
            else {
               
copy($src . '/' . $file,$dst . '/' . $file);
            }
        }
    }
   
closedir($dir);
}
?>

A nice simple trick if you need to make sure the folder exists first:

<?php

$srcfile
='C:\File\Whatever\Path\Joe.txt';
$dstfile='G:\Shared\Reports\Joe.txt';
mkdir(dirname($dstfile), 0777, true);
copy($srcfile, $dstfile);

?>

That simple.

It's worth noting that copy() sets the destination file's last modified time/date.

you can also try xcopy command by using Shell to move/copy files/folders from one place to another
here is the code:

<?php
exec
('xcopy c:\\myfolder d:\\myfolder /e/i', $a, $a1);
?>

by executing this command, it will move folder along with all contents to destination.

My own 'cp -R' written in PHP.

Hopefully it will work for your situation. I'm using it in a web based file manager for my CMS.

<?php

    define
('DS', DIRECTORY_SEPARATOR); // I always use this short form in my code.

   
function copy_r( $path, $dest )
    {
        if(
is_dir($path) )
        {
            @
mkdir( $dest );
           
$objects = scandir($path);
            if(
sizeof($objects) > 0 )
            {
                foreach(
$objects as $file )
                {
                    if(
$file == "." || $file == ".." )
                        continue;
                   
// go on
                   
if( is_dir( $path.DS.$file ) )
                    {
                       
copy_r( $path.DS.$file, $dest.DS.$file );
                    }
                    else
                    {
                       
copy( $path.DS.$file, $dest.DS.$file );
                    }
                }
            }
            return
true;
        }
        elseif(
is_file($path) )
        {
            return
copy($path, $dest);
        }

            return
false;

On Windows (not sure about Linux) copy will overwrite an existing file but will not change the case of the existing filename.

In other words if I have a file named "Myfile.txt" and I overwrite it using copy with a file named "MyFile.txt" it will overwrite it but the filename will remain "Myfile.txt".

If this is a problem (as it was for me) use unlink to delete the existing file first.

As far as recursive copy, something like this seems to work fine for me:

<?php
$output
= shell_exec( " cp -r -a dir_source/* dir_dest 2>&1 " )
echo
$output
?>

Of course you need to get all your permissions clear.  You can do the necessary stuff to use variables.

You could also do this to create the destination directory:

<?php
shell_exec
( " cp -r -a dir_source dir_dest 2>&1 " )
?>

This will create a new directory called "dir_dest" if it does not already exist. This is a bit risky though if your situation is ambiguous, and you want to continue to make backups etc, 'cause if you do it twice you end up with:

dir_destination/dir_source

to avoid that one could do something like:

<?php
shell_exec
( " mkdir dir_dest;  cp -r -a dir_source/* dir_dest 2>&1 " )
?>

Maybe someone can tell me when or why it would be better to use all that PHP code I see here.

Below a code snippet for downloading a file from a web server to a local file.

It demonstrates useful customizations of the request (such as setting a User-Agent and Referrer, often required by web sites), and how to download only files if the copy on the web site is newer than the local copy.

It further demonstrates the processing of response headers (if set by server) to determine the timestamp and file name. The file type is checked because some servers return a 200 OK return code with a textual "not found" page, instead of a proper 404 return code.

<?php
// $fURI:         URL to a file located on a web server
// $target_file:    Path to a local file   

if ( file_exists( $target_file ) ) {
   
$ifmodhdr = 'If-Modified-Since: '.date( "r", filemtime( $target_file ) )."\r\n";
}
else {

}

// set request header for GET with referrer for modified files, that follows redirects           
$arrRequestHeaders = array(
   
'http'=>array(
       
'method'        =>'GET',
       
'protocol_version'    =>1.1,
       
'follow_location'    =>1,
       
'header'=>    "User-Agent: Anamera-Feed/1.0\r\n" .
                    
"Referer: $source\r\n" .
           
$ifmodhdr
           
)
        );
$rc = copy( $fURI, $target_file, stream_context_create($arrRequestHeaders) );

// HTTP request completed, preserve system error, if any

}
else {
   
// No HTTP status and no error
   
throw new customException( "Unknown HTTP response accessing $fURI: $http_response_header[0]", -1 );
}
?>

Notes:
1. Currently copy() does NOT appropriately handle the 304 response code. Instead of NOT performing a copy (possibly setting the RC), it will overwrite the target file with an zero length file.
2. There may be a problem accessing a list of remote files when HTTP 1.1 protocol is used. If you experience time-out errors, try the default 1.0 protocol version.

some hosts disable copy() function and say its for security

and for some copy is important so this is and simple function that do same as copy function effect

how smart php can help us l like php

<?php
   
function copyemz($file1,$file2){
         
$contentx =@file_get_contents($file1);
                  
$openedfile = fopen($file2, "w");
                  
fwrite($openedfile, $contentx);
                  
fclose($openedfile);
                    if (
$contentx === FALSE) {
                   
$status=false;
                    }else
$status=true;
                   
                    return
$status;

This function creates a new filename to use for a copy of the given filename, its behaviour was mostly sto^Wborrowed from how the OS X Finder (*1) does it.
Note it *doesn't* actually copy the file, it just returns the new name. I needed it to work regardless of data source (filesystem, ftp, etc).

It also tries to match the current name as neatly as possible:
foo.txt -> foo copy.txt -> foo copy 1.txt -> foo copy 2.txt [etc]
foo.bar.baz.jpg -> foo.bar.baz copy.jpg
foobar -> foobar copy -> foobar copy 1 [etc]
".txt" -> .txt copy, and "txt." -> txt. copy
file.longextension -> file.longextension copy

It keeps trying until it finds a name that is not yet taken in $list, or until it looped 500 times (change as needed).

If the renamed file becomes longer than max filename length, it starts chopping away at the end of the part before where it adds " copy": reallylong...filename.txt -> reallylong...filena copy.txt

<?php

// $orig = current name, of course
// $list = array of filenames in the target directory (if none given, it will still return a new name)
// $max = max length of filename
function duplicate_name($orig, $list = array(), $max = 64) {
 
$ext = '';
 
$counter = 0;
 
$list = (array) $list;
 
$max = (int) $max;
 
$newname = $orig;
  do {
   
$name = $newname; # name in, newname out
   
if (preg_match('/ copy$| copy \d+$/', $name, $matches)) {
     
// don't even check for extension, name ends with " copy[ digits]"
    // preg hereunder matches anything with at least one period in the middle and an extension of 1-5 characters
   
}elseif (preg_match('/(.+)\.([^.]{1,5})$/', $name, $parts)) {
     
// split to name & extension
     
list($name, $ext) = array($parts[1], $parts[2]);
    }
    if (
preg_match('/ copy (\d+)$/', $name, $digits)) {
     
$newname = substr($name, 0, - strlen($digits[1])) . ($digits[1] + 1);
     
# $cutlen is only used for the bit at the end where it checks on max filename length
     
$cutlen = 6 + strlen($digits[1]+1); // ' copy ' + digits
   
}elseif(preg_match('/ copy$/', $name, $digits)) {
     
$newname = $name . ' 1';
     
$cutlen = 7; // ' copy' + ' 1'
   
}else{
     
$newname = $name . ' copy';
     
$cutlen = 5; // ' copy'
   
}
    if (
$ext) {
     
$newname .= '.' . $ext;
     
$cutlen += strlen($ext) + 1;
    }
    if (
$max > 0) {
      if (
strlen($newname) > $max) {
       
$newname = substr($newname, 0, max($max - $cutlen, 0)) . substr($newname, -$cutlen);
        if (
strlen($newname) > $max) {echo "duplicate_name() error: Can't keep the new name under given max length.\n"; return false;}
      }
    }
    if (
$counter++ > 500) {echo "duplicate_name() error: Too many similarly named files or infinite while loop.\n"; return false;}
  } while (
in_array($newname, $list));
  return
$newname;
}

?>

*1) The Finder seems to check the extension vs a list of known extensions, this function considers it valid if it's 5 or fewer characters long.

ps. sorry for taking up so much space! :-)

It seems as though you can only use move_uploaded_file() once on a temporary file that has been uploaded through a form. Most likely the action this function takes destroys the temporary file after it has been moved, assuming permanent placement on a file system.

Attempting to use the function again in the same PHP script will return false and not move the file.

I ran into this when an image that was uploaded did not need resizing (smaller than a size threshold) and after moving the temporary upload to the "originals" directory, an attempt was made to again move the temporary file to another folder.

This behavior is understandable, but be careful - in this instance, I simply used copy() on the file that was already uploaded.

you can try this code if you don't having permission to access the shell
this code is alternative for file copy

<?php
$source
= 'myfile.doc';
$destination = 'clonefile.doc';

$data = file_get_contents($source);

$handle = fopen($destination, "w");
fwrite($handle, $data);
fclose($handle);
?>
