filesize
Gets file size
(PHP 4, PHP 5)
int filesize ( string filename )
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.
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)).
Examples
Example 636. filesize() example
<?php
// outputs e.g. somefile.txt: 1024 bytes
$filename = 'somefile.txt';
echo $filename . ': ' . filesize($filename) . ' bytes';
?>
Notes
The results of this function are cached. See clearstatcache() for more details.
As of PHP 5.0.0 this function can also be used with some URL wrappers. Refer to Appendix O, List of Supported Protocols/Wrappers for a listing of which wrappers support stat() family of functionality.
