filesize
(PHP 4, PHP 5)
filesize — Gets file size
Beskrivelse
Gets the size for the given file.
Parameterliste
- filename
-
Path to the file.
Returneringsværdier
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, 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)).
Eksempler
Example#1 filesize() example
<?php
// outputs e.g. somefile.txt: 1024 bytes
$filename = 'somefile.txt';
echo $filename . ': ' . filesize($filename) . ' bytes';
?>
