一、在本目录下新建目录 ?php $dir_url = 'aaa/'; if(!is_dir($dir_url)) { mkdir($dir_url, 0777); } ? 二、在级联创建目录 ?php $dir_url = '../../usr/aaa/'; if(!is_dir($dir_url)) { mkdir($dir_url, 0777, true); } ? 默认为false,true为级联创建目录

一、在本目录下新建目录

$dir_url = 'aaa/';
if(!is_dir($dir_url)) {
   mkdir($dir_url, 0777);
}
?>

二、在级联创建目录

$dir_url = '../../usr/aaa/';
if(!is_dir($dir_url)) {
   mkdir($dir_url, 0777, true);
}
?>

 

默认为false,true为级联创建目录,为true是才能新建成功,需注意。
