(PHP 4, PHP 5)
fstat — Gets information about a file using an open file pointer
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.
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.
