filesize - Gets file size
Code Examples

filesize( string$filename ): int|false

Gets the size for the given file.



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.


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.

Exceptions and Errors

Upon failure, an E_WARNING is emitted.



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 to determine which wrappers support stat family of functionality.
