# fstat

(PHP 4 , PHP 5)

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

## Description

array fstat ( resource handle )

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

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

範例 1. fstat() 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
    )
