    (PHP 5 >= 5.3.2, PHP 7)

    获取真实目录缓存的详情

    说明

    realpath_cache_get(void): array

    获得真实路径缓存的详情。

    返回值

    返回真实路径缓存详情的数组。键是原始路径以及值为具体信息数组,含有该解析的路径,过期时间以及其他的更多选项。

    范例

    Example #1realpath_cache_get()example

    <?php
    var_dump(realpath_cache_get());
    ?>
    

    以上例程的输出类似于:

    array(2) {
      ["/test"]=>
      array(4) {
        ["key"]=>
        int(123456789)
        ["is_dir"]=>
        bool(true)
        ["realpath"]=>
        string(5) "/test"
        ["expires"]=>
        int(1260318939)
      }
      ["/test/test.php"]=>
      array(4) {
        ["key"]=>
        int(987654321)
        ["is_dir"]=>
        bool(false)
        ["realpath"]=>
        string(12) "/root/test.php"
        ["expires"]=>
        int(1260318939)
      }
    }

    Note that the realpath cache is not used if either safe_mode is on or an open_basedir restriction is in effect.
    This is having a huge performance effect, causing lots of calls to lstat.
