closedir()

(PHP 4, PHP 5, PHP 7)

关闭目录句柄

说明

closedir([resource $dir_handle]): void

关闭由$dir_handle指定的目录流。流必须之前被opendir()所打开。

参数

$dir_handle

目录句柄的resource，之前由opendir()所打开的。如果目录句柄没有指定，那么会假定为是opendir()所打开的最后一个句柄。

范例

Example #1closedir()例子

<?php
$dir = "/etc/php5/";
// Open a known directory, read directory into variable and then close
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        $directory = readdir($dh);
        closedir($dh);
    }
}
?>

About deleting a directory after doing a readdir/closedir on it... I'm not sure if this is the solution, but you could try to chdir("/"); before the rmdir to make absolutely sure you aren't standing in the directory (i.e trying to pull out the rug from under yourself).
