本文实例讲述了php递归创建目录的方法,分享给大家供大家参考。

具体实现代码如下:

<&#63;php
function mk_dir($path){
 //第1种情况,该目录已经存在
 if(is_dir($path)){
 return;
 }
 //第2种情况,父目录存在,本身不存在
 if(is_dir(dirname($path))){
 mkdir($path);
 }
 //第3种情况,父目录不存在
 if(!is_dir(dirname($path))){
 mk_dir(dirname($path));//创建父目录
 mkdir($path);
 }
}
$path = './e/b/c/f';
mk_dir($path);
&#63;>
Copy after login

换成三元运算,代码如下:

<&#63;php
function mk_dir($path){
 //第1种情况,该目录已经存在
 if(is_dir($path)){
 return;
 }
 //三元运算
 return is_dir(dirname($path)||mk_dir(dirname($path)&#63;mkdir($path):false;
}
$path = './e/b/c/f';
mk_dir($path);
&#63;>
Copy after login

希望本文所述对大家的php程序设计有所帮助。
