filesize

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

filesizeGets file size

Description

filesize(string $filename): int|false

Gets the size for the given file.

Parameters

filename

Path to the file.

Return Values

Returns the size of the file in bytes, or false (and generates an error of level E_WARNING) in case of an error.

Note: Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results for files which are larger than 2GB.

Errors/Exceptions

Upon failure, an E_WARNING is emitted.

Examples

Example #1 filesize() example

<?php

// outputs e.g. somefile.txt: 1024 bytes

$filename = 'somefile.txt';
echo
$filename . ': ' . filesize($filename) . ' bytes';

?>

Notes

Note: The results of this function are cached. See clearstatcache() for more details.

Tip

As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to Supported Protocols and Wrappers to determine which wrappers support stat() family of functionality.

Extremely simple function to get human filesize.
<?php
function human_filesize($bytes, $decimals = 2) {
$sz = 'BKMGTP';
$factor = floor((strlen($bytes) - 1) / 3);
return
sprintf("%.{$decimals}f", $bytes / pow(1024, $factor)) . @$sz[$factor];
}
?>

if you recently appended something to file, and closed it then this method will not show appended data:
<?php
// get contents of a file into a string
$filename = "/usr/local/something.txt";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);
?>
You should insert a call to clearstatcache() before calling filesize()
I've spent two hours to find that =/

Slightly edited version of the function from rommel at rommelsantor dot com. Now it returns a two characters file size which is a bit more convenient to read.

<?php
function human_filesize($bytes, $decimals = 2) {
$factor = floor((strlen($bytes) - 1) / 3);
if (
$factor > 0) $sz = 'KMGT';
return
sprintf("%.{$decimals}f", $bytes / pow(1024, $factor)) . @$sz[$factor - 1] . 'B';
}

print
human_filesize(12, 0); // 12B
print human_filesize(1234567890, 4); // 1.1498GB
print human_filesize(123456789, 1); // 117.7MB
print human_filesize(12345678901234, 5); // 11.22833TB
print human_filesize(1234567, 3); // 1.177MB
print human_filesize(123456); // 120.56KB
?>

I removed the P units because strlen doesn't seem to work as expected with integers longer than 14 digits. Though it might be only my system's limitation.

The first example given may lead one to assume that this function works with a local filename e.g. $fs = filesize("error_log") but if you manually delete some text, then save and close the file, the next time you check filesize("error_log") it will return the original value, because the value is cached for performance reasons. If you didn't know this, it would look like a nasty bug.

So, everyone tells you to insert clearstatcache() which is supposed to clear the cached value and allow you to retrieve the current file size but it still does nothing and looks like another bug!

However, I found that if you always specify the FULL PATH
e.g. $fs = filesize("/user/some/path/error_log");
then clearstatcache() is not even needed.

This function also can be great for browser caching controll. For example, you have a stylesheet and you want to make sure everyone has the most recent version. You could rename it every time you edit it, but that would be a waste of time. Instead, you can do like:

<?php

echo '<link rel="stylesheet" href="style.css?ver=1.'.filesize(dirname(__FILE__).'/style.css').'.'.filemtime(dirname(__FILE__).'/style.css').'.0">';

?>

Sample output:

<link rel="stylesheet" href="style.css?ver=1.8824.1499869132.0">

This also can be apply for JS and also images with same name.

This function quickly calculates the size of a directory:
http://aidanlister.com/repos/v/function.dirsize.php

You can convert filesizes to a human readable size using:
http://aidanlister.com/repos/v/function.size_readable.php

For a faster (unix only) implementation, see function.disk-total-space, note #34100
http://www.php.net/manual/en/function.disk-total-space.php#34100

Also of interest is this wikipedia article, discussing the difference between a kilobyte (1000) and a kibibyte (1024).

This functions returns the exact file size for file larger than 2 GB on 32 bit OS:

<?php
function file_get_size($file) {
//open file
$fh = fopen($file, "r");
//declare some variables
$size = "0";
$char = "";
//set file pointer to 0; I'm a little bit paranoid, you can remove this
fseek($fh, 0, SEEK_SET);
//set multiplicator to zero
$count = 0;
while (
true) {
//jump 1 MB forward in file
fseek($fh, 1048576, SEEK_CUR);
//check if we actually left the file
if (($char = fgetc($fh)) !== false) {
//if not, go on
$count ++;
} else {
//else jump back where we were before leaving and exit loop
fseek($fh, -1048576, SEEK_CUR);
break;
}
}
//we could make $count jumps, so the file is at least $count * 1.000001 MB large
//1048577 because we jump 1 MB and fgetc goes 1 B forward too
$size = bcmul("1048577", $count);
//now count the last few bytes; they're always less than 1048576 so it's quite fast
$fine = 0;
while(
false !== ($char = fgetc($fh))) {
$fine ++;
}
//and add them
$size = bcadd($size, $fine);

In case of you have a redirection in the server (like Redirect Permanent in the .htaccess)

In this case we have for exemple:
[content-length] => Array

(

[0] => 294 // Size requested file

[1] => 357556 // Real Size redirected file

Under Windows 10 filesize obviously cannot work with relative path names. Use absolute path instead. $size = filesize(".\\myfile.txt"); does not work for me while "d:\\MyFiles\\Myfile.txt" will do. The same applys to similar functions like is_file() or stat(). They won't work correctly unless given an absolute path.

A fast implementation that determines actual file size of large files (>2GB) on 32-bit PHP:

function RealFileSize($fp)
{
$pos = 0;
$size = 1073741824;
fseek($fp, 0, SEEK_SET);
while ($size > 1)
{
fseek($fp, $size, SEEK_CUR);

if (fgetc($fp) === false)
{
fseek($fp, -$size, SEEK_CUR);
$size = (int)($size / 2);
}
else
{
fseek($fp, -1, SEEK_CUR);
$pos += $size;
}
}

while (fgetc($fp) !== false) $pos++;

return $pos;
}

Input is an open file handle. Return value is an integer for file sizes < 4GB, floating-point otherwise.

This starts out by skipping ~1GB at a time, reads a character in, repeats. When it gets into the last GB, it halves the size whenever the read fails. The last couple of bytes are just read in.

Some people might have concerns over this function because $pos will become a floating point number after exceeding integer limits and they know of floating point's tendencies to be inaccurate. On most computers that correctly implement the IEEE floating point spec, $pos will be accurate out to around 9 *petabytes*. Unless you are working with multi-petabyte files in PHP or the code is executing on strange hardware, this function is going to be more than sufficient. Every part of this function has been carefully crafted to deal with 32-bit deficiencies.

return "El fichero no existe";
}
$bytes = filesize($file);
$sizes = 'BKMGTP';
if (isset($size)){
$factor = strpos($sizes, $size[0]);
if ($factor===false){
return "El tamaño debe ser B, K, M, G, T o P";
}
} else {
$factor = floor((strlen($bytes) - 1) / 3);
$size = $sizes[$factor];
}
return number_format($bytes / pow(1024, $factor), $decimals, $dec_sep, $thousands_sep).' '.$size;

I have a cli script running that use the filesize function on a ssh2_sftp connection. It has the >2Gb limit issue, while it does not have that issue locally. I have managed to get around this by doing a "du -sb" command through ssh2_shell.

The following function takes the ssh2_connect resource and the path as input. It may not be neat, but it solves the problem for the moment.

<?php
function fSSHFileSize($oConn, $sPath) {
if(
false !== ($oShell = @ssh2_shell($oConn, 'xterm', null, 500, 24, SSH2_TERM_UNIT_CHARS))) {

Here's the best way (that I've found) to get the size of a remote file. Note that HEAD requests don't get the actual body of the request, they just retrieve the headers. So making a HEAD request to a resource that is 100MB will take the same amount of time as a HEAD request to a resource that is 1KB.

<?php
$remoteFile
= 'http://us.php.net/get/php-5.2.10.tar.bz2/from/this/mirror';
$ch = curl_init($remoteFile);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); //not necessary unless the file redirects (like the PHP example we're using here)
$data = curl_exec($ch);
curl_close($ch);
if (
$data === false) {
echo
'cURL failed';
exit;
}

$contentLength = 'unknown';
$status = 'unknown';
if (
preg_match('/^HTTP\/1\.[01] (\d\d\d)/', $data, $matches)) {
$status = (int)$matches[1];
}
if (
preg_match('/Content-Length: (\d+)/', $data, $matches)) {
$contentLength = (int)$matches[1];
}

echo
'HTTP Status: ' . $status . "\n";
echo
'Content-Length: ' . $contentLength;
?>

Result:

HTTP Status: 302
Content-Length: 8808759

some notes and modifications to previous post.
refering to RFC, when using HTTP/1.1 your request (either GET or POST or HEAD) must contain Host header string, opposite to HTTP/1.1 where Host ain't required. but there's no sure how your remote server would treat the request so you can add Host anyway (it won't be an error for HTTP/1.0).
host value _must_ be a host name (not CNAME and not IP address).

this function catches response, containing Location header and recursively sends HEAD request to host where we are moved until final response is met.
(you can experience such redirections often when downloading something from php scripts or some hash links that use apache mod_rewrite. most all of dowloading masters handle 302 redirects correctly, so this code does it too (running recursively thru 302 redirections).)

[$counter302] specify how much times your allow this function to jump if redirections are met. If initial limit (5 is default) expired -- it returns 0 (should be modified for your purposes whatever).0
ReadHeader() function is listed in previous post
(param description is placed there too).

<?php
function remote_filesize_thru( $ipAddress, $url, $counter302 = 5 )
{
$socket = fsockopen( "10.233.225.2", 8080 );
if( !
$socket )
{
// failed to open TCP socket connection
// do something sensible here besides exit();
echo "<br>failed to open socket for [$ipAddress]";
exit();
}

// just send HEAD request to server
$head = "HEAD $url HTTP/1.0\r\nConnection: Close\r\n\r\n";
// you may use HTTP/1.1 instead, then your request head string _must_ contain "Host: " header
fwrite( $socket, $head );

// read the response header
$header = ReadHeader( $socket );
if( !
$header )
{
// handle empty response here the way you need...
Header( "HTTP/1.1 404 Not Found" );
exit();
}

fclose( $socket );

// check for "Location" header
$locationMarker = "Location: ";
$pos = strpos( $header, $locationMarker );
if(
$pos > 0 )
{
$counter302--;
if(
$counter302 < 0 )
{
// redirect limit (5 by default) expired -- return some warning or do something sensible here
echo "warning: too long redirection sequence";
return
0;
}

// Location is present -- we should determine target host and move there, like any downloading masters do...
// no need to use regex here
$end = strpos( $header, "\n", $pos );
$location = trim( substr( $header, $pos + strlen( $locationMarker ), $end - $pos - strlen( $locationMarker ) ), "\\r\\n" );

// extract pure host (without "http://")
$host = explode( "/", $location );

This is an updated version of my previous filesize2bytes.
The return type now it's really an int.

<?php
/**
* Converts human readable file size (e.g. 10 MB, 200.20 GB) into bytes.
*
* @param string $str
* @return int the result is in bytes
* @author Svetoslav Marinov
* @author http://slavi.biz
*/
function filesize2bytes($str) {
$bytes = 0;

$bytes_array = array(
'B' => 1,
'KB' => 1024,
'MB' => 1024 * 1024,
'GB' => 1024 * 1024 * 1024,
'TB' => 1024 * 1024 * 1024 * 1024,
'PB' => 1024 * 1024 * 1024 * 1024 * 1024,
);

$bytes = floatval($str);

if (
preg_match('#([KMGTP]?B)$#si', $str, $matches) && !empty($bytes_array[$matches[1]])) {
$bytes *= $bytes_array[$matches[1]];
}

$bytes = intval(round($bytes, 2));

return
$bytes;
}
?>

My solution for calculating the directory size:

<?php
/**
* Get the directory size
* @param directory $directory
* @return integer
*/
function dirSize($directory) {
$size = 0;
foreach(new
RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory)) as $file){
$size+=$file->getSize();
}
return
$size;
}
?>

Using fseek is really slow. This one really better and faster.

if (strtoupper(substr(PHP_OS, 0, 3)) == 'WIN') {
$size = trim(exec("for %F in (\"" . $file . "\") do @echo %~zF"));
}
elseif ((PHP_OS == 'Linux') || (PHP_OS == 'FreeBSD') || (PHP_OS == 'Unix') || (PHP_OS == 'SunOS')) {
$size = trim(shell_exec("stat -c%s " . escapeshellarg($file)));
} else {
$size = filesize($file);
}

"Note: Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results for files which are larger than 2GB."

This ought to be a warning and not a note: filesize - as some of the other comments suggest - is useless for applications where custom action must be taken for large files.
