fstat

(PHP 4, PHP 5, PHP 7)

fstatGets information about a file using an open file pointer

설명

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.

인수

handle

일반적으로 fopen()으로 생성하는 파일 시스템 포인터 resource.

반환값

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

예제

Example #1 fstat() example

<?php

// open a file

// gather statistics

// print only the associative part
print_r(array_slice($fstat13));

?>

위 예제의 출력 예시:

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

Another ftp_get_contents() approach, using a temperary stream handler. Returns file contents of remote file as string.

<?php
function ftp_get_contents ($conn_id, $remote_filename) {
   
//Create temp handler:
   
$tempHandle = fopen('php://temp', 'r+');

   
//Get file from FTP assuming that it exists:
   
ftp_fget($conn_id, $tempHandle, $remote_filename, FTP_ASCII, 0));

   
//Getting detailed stats to check filesize:
   
$fstats = fstat($tempHandle);

    return
fread($tempHandle, $fstats['size']);
}
?>

(It is recommended to add some error handling)

Remember atime will not be updated by simple read access to the file unless you take care for that in the mounting parameters of your filesystem. 

Instead of atime, mtime will be delivered. But mtime only will be updated, if the contents of the file has changed.

Due to this behavior take care in your Session-System. Using session_start() will not be sufficiant to keep your sessions alive. You should write into the Session, e. g. : 

$_SESSION = time(); 

That retriggers your mtime and atime, even if the mounting parameter for atime is set to "noatime" or is missing, dependent of the used file System.
