# filesize

(PHP 4, PHP 5, PHP 7)

filesize — Gets file size

### Description

int filesize ( string `$filename` )

Gets the size for the given file.

### 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.

### Examples

Example #1 filesize() 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() 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() family of functionality.
