  • posix_getegid()

    (PHP 4, PHP 5, PHP 7)

    Return the effective group ID of the current process

    说明

    posix_getegid(void): int

    Return the numeric effective group ID of the current process.

    返回值

    Returns an integer of the effective group ID.

    范例

    posix_getegid() example

    This example will print out the effective group id, once it is changed with posix_setegid().

    <?php
    echo 'My real group id is '.posix_getgid(); //20
    posix_setegid(40);
    echo 'My real group id is '.posix_getgid(); //20
    echo 'My effective group id is '.posix_getegid(); //40
    ?>
    

    注释

    posix_getegid() is different than posix_getgid() because effective group ID can be changed by a calling process using posix_setegid().
