    lstat

    (PHP 4, PHP 5, PHP 7)

    lstat — Gives information about a file or symbolic link

    설명

    array lstat ( string $filename )

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

    인수

    filename

    Path to a file or a symbolic link.

    반환값

    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.

    예제

    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'));
    ?>

    위 예제의 출력 예시:

    Information that differs between the two files. 

    Array
(
    [ino] => 97236376
    [mode] => 33188
    [size] => 34
    [atime] => 1223580003
    [mtime] => 1223581848
    [ctime] => 1223581848
    [blocks] => 8
)

    오류/예외

    실패 시, E_WARNING이 발생합니다.

    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
