filesize

FILESIZE(3)								 1							       FILESIZE(3)

filesize - Gets file size

SYNOPSIS

       int filesize (string  $filename)

DESCRIPTION

	Gets the size for the given file.

PARAMETERS

	      o $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(3) 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(3) 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(3) family of functionality.
