A better example, to illustrate the differences in speed for large files, between fgets and stream_get_line.
This example simulates situations where you are reading potentially very long lines, of an uncertain length (but with a maximum buffer size), from an input source.
As Dade pointed out, the previous example I provided was much to easy to pick apart, and did not adequately highlight the issue I was trying to address.
Note that specifying a definitive end-character for fgets (ie: newline), generally decreases the speed difference reasonably significantly.
#!/usr/bin/php
<?php
$plaintext=file_get_contents('http://loripsum.net/api/60/verylong/plaintext'); # Should be around 90k characters
$plaintext=str_replace("\n"," ",$plaintext); # Get rid of newlines
$fp=fopen("/tmp/SourceFile.txt","w");
for($i=0;$i<100000;$i++) {
fputs($fp,substr($plaintext,0,rand(4096,65534)) . "\n");
}
fclose($fp);
$fp=fopen("/tmp/SourceFile.txt","r");
$start=microtime(true);
while($line=fgets($fp,65535)) {
1;
}
$end=microtime(true);
fclose($fp);
$delta1=($end - $start);
$fp=fopen("/tmp/SourceFile.txt","r");
$start=microtime(true);
while($line=stream_get_line($fp,65535)) {
1;
}
$end=microtime(true);
fclose($fp);
$delta2=($end - $start);
$pdiff=$delta1/$delta2;
print "stream_get_line is " . ($pdiff>1?"faster":"slower") . " than fgets - pdiff is $pdiff\n";
?>
$ ./testcase.php
stream_get_line is faster than fgets - pdiff is 1.760398041785
Note that, in a vast majority of situations in which php is employed, tiny differences in speed between system calls are of negligible importance.
fgets
(PHP 4, PHP 5, PHP 7)
fgets — Obtiene una línea desde el puntero a un fichero
Descripción
string fgets
( resource
$handle
[, int $length
] )Obtiene una línea desde el puntero al fichero.
Parámetros
-
handle -
El fichero al que se apunta debe ser válido, y debe apuntar a un fichero abierto por fopen() o fsockopen() (y que todavía no esté cerrado por fclose()).
-
length -
La lectura termina cuando se han leído
length- 1 bytes, o una nueva línea (la cual está incluida en el valor de retorno), o un EOF (lo que suceda primero). Si no se especifica una longitud, se seguirá leyendo desde el flujo hasta que alcance el final de la línea.Nota:
Hasta PHP 4.3.0, al omitirlo se asumía una longitud de línea de 1024. Si la mayoría de las lineas del fichero son todas mayores de 8KB, es más eficiente para el script en cuestión de recursos especificar la longitud máxima de línea.
Valores devueltos
Devuelve una cadena de hasta length - 1 bytes leídos desde
el fichero apuntado por handle. Si no hay más datos
que leer en el puntero al fichero, devuelve FALSE.
Si se produjo un error, devuelve FALSE.
Historial de cambios
| Versión | Descripción |
|---|---|
| 4.3.0 | fgets() ahora es segura al trabajar con datos binarios |
Ejemplos
Ejemplo #1 Leer un fichero línea a línea
<?php
$gestor = @fopen("/tmp/inputfile.txt", "r");
if ($gestor) {
while (($búfer = fgets($gestor, 4096)) !== false) {
echo $búfer;
}
if (!feof($gestor)) {
echo "Error: fallo inesperado de fgets()\n";
}
fclose($gestor);
}
?>
Notas
Nota: Si sufre problemas con PHP no reconociendo los finales de línea cuando lee o crea ficheros en Macintosh, puede probar de activar la opción de configuración en tiempo de ejecución auto_detect_line_endings para intentar resolver el problema.
Nota:
Las personas que suele usar la semántica tipo 'C' de fgets() deberían observar la diferencia de cómo se devuelve EOF.

One thing I discovered with fgets, at least with PHP 5.1.6, is that you may have to use an IF statement to avoid your code running rampant (and possibly hanging the server). This can cause problems if you do not have root access on the server on which you are working.
This is the code I have implemented ($F1 is an array):
<?php
if($fh = fopen("filename","r")){
while (!feof($fh)){
$F1[] = fgets($fh,9999);
}
fclose($fh);
}
?>
I have noticed that without the IF statement, fgets seems to ignore when $fh is undefined (i.e., "filename" does not exist). If that happens, it will keep attempting to read from a nonexistent filehandle until the process can be administratively killed or the server hangs, whichever comes first.

It appears that fgets() will return FALSE on EOF (before feof has a chance to read it), so this code will throw an exception:
while (!feof($fh)) {
$line = fgets($fh);
if ($line === false) {
throw new Exception("File read error");
}
}

WARNING! fgets() and I presume any read() call to a file handle, e.g.
while(!feof(STDIN)) {
$line = fgets(STDIN);
...do something useful with $line...
}
...will result in a timeout after a default time of 60 seconds on my install. This behavior is non standard (not POSIX like) and seems to me to be a bug, or if not a major caveat which should be documented more clearly.
After the timeout fgets() will return FALSE (=== FALSE), however, you can check to see if the stream (file handle) has really closed by checking feof($stream), e.g.
while(!feof(STDIN)) {
$line = fgets(STDIN);
if($line === FALSE) {
if(feof(STDIN)) {
break;
}
continue;
}
...do something useful with $line...

Regarding Leigh Purdie's comment (from 4 years ago) about stream_get_line being better for large files, I decided to test this in case it was optimized since then and I found out that Leigh's comment is just completely incorrect
fgets actually has a small amount of better performance, but the test Leigh did was not set up to produce good results
The suggested test was:
$ time yes "This is a test line" | head -1000000 | php -r '$fp=fopen("php://stdin","r"); while($line=stream_get_line($fp,65535,"\n")) { 1; } fclose($fp);'
0m1.616s
$ time yes "This is a test line" | head -1000000 | php -r '$fp=fopen("php://stdin","r"); while($line=fgets($fp,65535)) { 1; } fclose($fp);'
0m7.392s
The reason this is invalid is because the buffer size of 65535 is completely unnecessary
piping the output of "yes 'this is a test line'" in to PHP makes each line 19 characters plus the delimiter
so while I don't know why stream_get_line performs better with an oversize buffer, if both buffer sizes are correct, or default, they have a negligable performance difference - although notably, stream_get_line is consistent - however if you're thinking of switching, make sure to be aware of the difference between the two functions, that stream_get_line does NOT append the delimiter, and fgets DOES append the delimiter
Here are the results on one of my servers:
Buffer size 65535
stream_get_line: 0.340s
fgets: 2.392s
Buffer size of 1024
stream_get_line: 0m0.348s
fgets: 0.404s
Buffer size of 8192 (the default for both)
stream_get_line: 0.348s
fgets: 0.552s
Buffer size of 100:
stream_get_line: 0.332s
fgets: 0.368s

For sockets, If you dont want fgets, fgetc etc... to block if theres no data there. set socket_set_blocking(handle,false); and socket_set_blocking(handle,true); to set it back again.

If you need to simulate an un-buffered fgets so that stdin doesnt hang there waiting for some input (i.e. it reads only if there is data available) use this :
<?php
function fgets_u($pStdn) {
$pArr = array($pStdn);
if (false === ($num_changed_streams = stream_select($pArr, $write = NULL, $except = NULL, 0))) {
print("\$ 001 Socket Error : UNABLE TO WATCH STDIN.\n");
return FALSE;
} elseif ($num_changed_streams > 0) {
return trim(fgets($pStdn, 1024));
}
}

Some people try to call feof before fgets, and then ignoring the return value of fgets. This method leads to processing value FALSE when reaching the end of file.
Bad example:
<?php
$f = fopen ("fgetstest.php", "r");
$ln= 0;
while (! feof ($f)) {
$line= fgets ($f);
++$ln;
printf ("%2d: ", $ln);
if ($line===FALSE) print ("FALSE\n");
else print ($line);
}
fclose ($f);
?>
Good example:
<?php
$f = fopen ("fgetstest.php", "r");
$ln= 0;
while ($line= fgets ($f)) {
++$ln;
printf ("%2d: ", $ln);
if ($line===FALSE) print ("FALSE\n");
else print ($line);
}
fclose ($f);
?>

For large files, consider using stream_get_line rather than fgets - it can make a significant difference.
$ time yes "This is a test line" | head -1000000 | php -r '$fp=fopen("php://stdin","r"); while($line=stream_get_line($fp,65535,"\n")) { 1; } fclose($fp);'

I had loads of trouble while reading with fgets on a WAMP (Windows server). On local the file went unto a <pre> tag without a hitch, but when I moved the code to a LAMP production server, every \r\n created two fgets and I got free empty lines.
I tried deleting with $string=str_replace("\r\n","\n",$string); but it had no effect whatsoever. The solution was to do an fread() and explode the contents by PHP_EOL and do a foreach($lines as $line) so every line did not get duplicated.
Here is the example code:
$file=fopen("test.txt,"r");
$text=fread($file,filesize("test.txt"));
$lines=explode(PHP_EOL,$text);
foreach($lines as $line)
{
// Do something
}

The file pointer that fgets() uses can also be created with the proc_open() function and used with the stdout pipe created from the executed process.
David at Weintraub.name ¶
9 years ago
There's an error in the documentation:
The file pointer must be valid, and must point to a file successfully opened by fopen() or fsockopen() (and not yet closed by fclose()).
You should also add "popen" and "pclose" to the documentation. I'm a new PHP developer and went to verify that I could use "fgets" on commands that I used with "popen".

I think that the quickest way of read a (long) file with the rows in reverse order is
<?php
$myfile = 'myfile.txt';
$command = "tac $myfile > /tmp/myfilereversed.txt";
passthru($command);
$ic = 0;
$ic_max = 100; // stops after this number of rows
$handle = fopen("/tmp/myfilereversed.txt", "r");
while (!feof($handle) && ++$ic<=$ic_max) {
$buffer = fgets($handle, 4096);
echo $buffer."<br>";
}
fclose($handle);
?>
It echos the rows while it is reading the file so it is good for long files like logs.

I would have expected the same behaviour from these bits of code:-
<?php
/*This times out correctly*/
while (!feof($fp)) {
echo fgets($fp);
}
/*This times out before eof*/
while ($line=fgets($fp)) {
echo $line;
}
/*A reasonable fix is to set a long timeout*/
stream_set_timeout($fp, 180);
while ($line=fgets($fp)) {
echo $line;
}

When working with VERY large files, php tends to fall over sideways and die.
Here is a neat way to pull chunks out of a file very fast and won't stop in mid line, but rater at end of last known line. It pulled a 30+ million line 900meg file through in ~ 24 seconds.
NOTE:
$buf just hold current chunk of data to work with. If you try "$buf .=" (note 'dot' in from of '=') to append $buff, script will come to grinding crawl around 100megs of data, so work with current data then move on!
//File to be opened
$file = "huge.file";
//Open file (DON'T USE a+ pointer will be wrong!)
$fp = fopen($file, 'r');
//Read 16meg chunks
$read = 16777216;
//\n Marker
$part = 0;
while(!feof($fp)) {
$rbuf = fread($fp, $read);
for($i=$read;$i > 0 || $n == chr(10);$i--) {
$n=substr($rbuf, $i, 1);
if($n == chr(10))break;
//If we are at the end of the file, just grab the rest and stop loop
elseif(feof($fp)) {
$i = $read;
$buf = substr($rbuf, 0, $i+1);
break;
}
}
//This is the buffer we want to do stuff with, maybe thow to a function?
$buf = substr($rbuf, 0, $i+1);
//Point marker back to last \n point
$part = ftell($fp)-($read-($i+1));
fseek($fp, $part);
}
fclose($fp);

Even if this is not really related to PHP and its internals take care when using fgets for reading input from CLI on Linux systems as it may behave unexpected because of the limitations of arguments length on these systems. For example doing rtrim(fgets(STDIN), "\n") on a user input larger than 4095 characters will cut the the input string to 4095 characters. This shortcoming can be solved using "stty -icanon" before the script run, followed by a "stty icanon" after the script is run.

Saku's example may also be used like this:
<?php
@ $pointer = fopen("$DOCUMENT_ROOT/foo.txt", "r"); // the @ suppresses errors so you have to test the pointer for existence
if ($pointer) {
while (!feof($pointer)) {
$preTEXT = fgets($pointer, 999);
// $TEXT .= $preTEXT; this is better for a string
$ATEXT[$I] = $preTEXT; // maybe better as an array
$I++;
}
fclose($pointer);
}

Sometimes the strings you want to read from a file are not separated by an end of line character. the C style getline() function solves this. Here is my version:
<?php
function getline( $fp, $delim )
{
$result = "";
while( !feof( $fp ) )
{
$tmp = fgetc( $fp );
if( $tmp == $delim )
return $result;
$result .= $tmp;
}
return $result;
}
// Example:
$fp = fopen("/path/to/file.ext", 'r');
while( !feof($fp) )
{
$str = getline($fp, '|');
// Do something with $str
}
fclose($fp);

For anyone who wants a proper non-blocking fgets for sockets, there is a tiny snippet that does just that (performance should be horrible compared to fgets though):
<?php
function read_line_nb($handle)
{
static $buffer = '';
static $lastOffset = 0;
$buffer .= fread($handle, 0x1000);
if (preg_match('#\\R#', $buffer, $m, PREG_OFFSET_CAPTURE, $lastOffset)) {
$line = substr($buffer, 0, $m[0][1] + strlen($m[0][0]));
$buffer = substr($buffer, $m[0][1] + strlen($m[0][0]));
return $line;
}
$lastOffset = strlen($buffer);
return false;
}
?>

Note that - afaik - fgets reads a line until it reaches a line feed (\\n). Carriage returns (\\r) aren't processed as line endings.
However, nl2br insterts a <br /> tag before carriage returns as well.
This is useful (but not nice - I must admit) when you want to store a more lines in one.
<?php
function write_lines($text) {
$file = fopen('data.txt', 'a');
fwrite($file, str_replace("\n", ' ', $text)."\n");
fclose($file);
}
function read_all() {
$file = fopen('data.txt', 'r');
while (!feof($file)) {
$line = fgets($file);
echo '<u>Section</u><p>nl2br'.($line).'</p>';
}
fclose($file);
}
?>
Try it.

fscanf($file, "%s\n") isn't really a good substitution for fgets(), since it will stop parsing at the first whitespace and not at the end of line!
(See the fscanf page for details on this)

fgets is SLOW for scanning through large files. If you don't have PHP 5, use fscanf($file, "%s\n") instead.

There seems to be an interaction between sockets and the auto_detect_line_endings setting that can cause rather peculiar behavior. Apparently, if the first line read from a socket is split across two TCP packets, the detector will look at the first TCP packet and determine that the system uses MacOS (\r) line endings, even though the LF is contained in the next packet. For example, this affected the PEAR Net_SMTP package, which would fail mysteriously for only some email servers.

It's worth noting that this function only assumes chr(10) as a line break, but not chr(13). Personally, I prefer using chr(13) as a line break.

If you use the example from the command-description, i recommend to trim the $buffer for further use. The line feed ist still at the end of the line. I saw this when using PHP CLI.
Like this, checking a file-list for existing entries:
$handle = fopen ("/tmp/files.txt", "r");
while (!feof($handle)) {
$buffer = fgets($handle, 4096);
if (file_exists(rtrim($filename,"\n"))) {
echo $buffer;
} else {
echo $buffer." has been removed."
}
fclose ($handle);

As you can see very close and fgets just coming just a little bit ahead. I suspect that fgets is reading backwards on the buffer or loads everything into its self then trys to figure it out where as a correct set buffer does the trick. Dade Brandon states that fgets lets you know how the line was delimited. stream_get_line lets you choose what you wanna call the delimiter using its 3rd option.
fgets has one more option that is important, you dont have to set the length of the line. So in a case where you may not know the length of the line maybe in handling Http protocol or something else like log lines you can simply leave it off and still get great performance.

If you need to read an entire file into a string, use file_get_contents(). fgets() is most useful when you need to process the lines of a file separately.

Dade Brandon states that fgets lets you know how the line was delimited. stream_get_line lets you choose what you wanna call the delimiter using its 3rd option.
fgets has one more option that is important, you dont have to set the length of the line. So in a case where you may not know the length of the line maybe in handling Http protocol or something else like log lines you can simply leave it off and still get great performance.
$ time yes "This is a test line" | head -1000000 | php -r '$fp=fopen("php://stdin","r"); while($line=fgets($fp)) { 1; } fclose($fp);'
real 0m0.261s
user 0m0.260s
sys 0m0.232s
This is better then with a buffer set.

This is a a simple function to detect end of line type for any file.
<?php
function detectEndOfLine($file)
{
$handle = @fopen($file, "r");
if ($handle)
{
$char=0;
while (!$eol || feof($handle))
{
$char++;
$line = fgets($handle, $char);
$eol = preg_match("/(\r)+/", $line)? "W" : "";
if(!$eol) $eol = preg_match("/(\n)+/", $line)? "L" : "";
}
return $eol;
fclose($handle);
}
}
?>
