filesize
FILESIZE(3) 1 FILESIZE(3)filesize - Gets file sizeSYNOPSIS
int filesize (string $filename)
DESCRIPTION
Gets the size for the given file.
PARAMETERS
o $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.
EXAMPLES
Example #1
filesize(3) example
<?php
// outputs e.g. somefile.txt: 1024 bytes
$filename = 'somefile.txt';
echo $filename . ': ' . filesize($filename) . ' bytes';
?>
ERRORS /EXCEPTIONS
Upon failure, an E_WARNING is emitted.
NOTES
Note
The results of this function are cached. See clearstatcache(3) 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(3) family of functionality.
