fstat in PHP

fstat — Gets information about a file using an open file pointer
Syntax:

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.

Parameters:

handle
A file system pointer resource that is typically created using fopen().

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



Example #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
)


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