filesize

(PHP 4, PHP 5, PHP 7)

Gets file size

int filesize ( string $filename )

Gets the size for the given file.

Parameters:

filename

Path to the file.

Returns:

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.

Exception:

Upon failure, an E_WARNING is emitted.

Notes:

The results of this function are cached. See clearstatcache() for more details.

Examples:
