php filesize function_PHP tutorial

php filesize function ​

filesize
(PHP 4, PHP 5)

filesize - Get file size

Description
international filesize(String$filename)
Get a file of a given size.

Parameters

File name
File path.


Return value
Returns the size of the file in bytes, or FALSE (and generates error level E_WARNING) in case of an error.

NOTE: Due to PHP's signature of integer types and the use of 32-bit integers by many platforms, filesize() may return unexpected results for files larger than 2GB in size. For file sizes of 2GB and 4GB this can usually be overcome using sprintf("%u", filesize($file)).

Example

Example of #1filesize()

// outputs e.g. somefile.txt: 1024 bytes

$filename = 'somefile.txt';
echo $filename . ': ' . filesize($filename) . ' bytes';

?>
