filesize
(PHP 4, PHP 5, PHP 7, PHP 8)
filesize — Gets file size
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

echo $filename . ': ' . filesize($filename) . ' bytes';
?>
Notes
