FSTAT(3)								 1								  FSTAT(3)

fstat - Gets information about a file using an open file pointer

SYNOPSIS
       array fstat (resource  $handle)

DESCRIPTION
	Gathers  the  statistics  of  the file opened by the file pointer $handle. This function is similar to the stat(3) function except that it
       operates on an open file pointer instead of a filename.

PARAMETERS
	      o $handle
		-A file system pointer resource that is typically created using fopen(3).

RETURN VALUES
	Returns an array with the statistics of the file; the format of the array is described in detail on the stat(3) manual page.

EXAMPLES
       Example #1

	      fstat(3) example

	      <?php

	      // open a file
	      $fp = fopen("/etc/passwd", "r");

	      // gather statistics
	      $fstat = fstat($fp);

	      // close the file
	      fclose($fp);

	      // print only the associative part
	      print_r(array_slice($fstat, 13));

	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [dev] => 771
		  [ino] => 488704
		  [mode] => 33188
		  [nlink] => 1
		  [uid] => 0
		  [gid] => 0
		  [rdev] => 0
		  [size] => 1114
		  [atime] => 1061067181
		  [mtime] => 1056136526
		  [ctime] => 1056136526
		  [blksize] => 4096
		  [blocks] => 8
	      )

NOTES
       Note

	      This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.
