本文实例讲述了php递归法读取目录及文件的方法。分享给大家供大家参考。具体如下:

这里实例分析php递归法读取目录及文件的方法,代码中包含较为详尽的注释,如下所示:

<&#63;php
function showdir($path){
 $dh = opendir($path);//打开目录
 while(($d = readdir($dh)) != false){
 //逐个文件读取,添加!=false条件,是为避免有文件或目录的名称为0
 if($d=='.' || $d == '..'){//判断是否为.或..,默认都会有
 continue;
 }
 echo $d."<br />";
 if(is_dir($path.'/'.$d)){//如果为目录
 showdir($path.'/'.$d);//继续读取该目录下的目录或文件
 }
 }
}

$path = './';//当前目录
showdir($path);
&#63;>
Copy after login

希望本文所述对大家的php程序设计有所帮助。
