filesize
(PHP 3, PHP 4 )
filesize -- Gets file size
Description
int filesize ( string filename)
Returns the size of the file in bytes, or FALSE in case
of an error.
Note: Because PHP's integer type is signed and many platforms
use 32bit integers, filesize() may return unexpected results
for files which are larger than 2GB. For files between 2GB
and 4GB in size this can usually be overcome by using sprintf("%u",
filesize($file)).
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 Appendix J for a listing of
which wrappers support stat() family of functionality.
Example 1. filesize() example
<?php
// outputs e.g. somefile.txt: 1024 bytes
$filename = 'somefile.txt';
echo $filename . ': ' . filesize($filename) . ' bytes';
?>
