lstat

(PHP 4, PHP 5, PHP 7)

lstatGives information about a file or symbolic link

Descrierea

lstat ( string $filename ) : array|false

Gathers the statistics of the file or symbolic link named by filename.

Parametri

filename

Path to a file or a symbolic link.

Valorile întoarse

See the manual page for stat() for information on the structure of the array that lstat() returns. This function is identical to the stat() function except that if the filename parameter is a symbolic link, the status of the symbolic link is returned, not the status of the file pointed to by the symbolic link.

On failure, false is returned.

Exemple

Example #1 Comparison of stat() and lstat()

<?php
symlink
('uploads.php''uploads');

// Contrast information for uploads.php and uploads
array_diff(stat('uploads'), lstat('uploads'));
?>

    [ino] => 97236376
    [mode] => 33188

Just for information and in reply to a previous message left 4 years ago by "salsi at icosaedro dot it" :

Files larger than 2 GiB can be handled on 64-bit Linux systems.

My test in a terminal is as follow (using <?php ;?> tags to colour the results for ease of reading) :

$ php -v
