The mkdir function in PHP creates directories (folders) recursively_PHP tutorial

In PHP, the mkdir function creates a directory. It cannot create a directory recursively. We need to traverse the directory and then call mkdir. Let’s take a look at the operation method.

Example

The code is as follows

Copy code

代码如下 复制代码 /** * Makes directory and returns BOOL(TRUE) if exists OR made. * * @param $path Path name * @return bool */ function rmkdir($path, $mode = 0755) { $path = rtrim(preg_replace(array("/\/", "//{2,}/"), "/", $path), "/"); $e = explode("/", ltrim($path, "/")); if(substr($path, 0, 1) == "/") { $e[0] = "/".$e[0]; } $c = count($e); $cp = $e[0]; for($i = 1; $i < $c; $i++) { if(!is_dir($cp) && !@mkdir($cp, $mode)) { return false; } $cp .= "/".$e[$i]; } return @mkdir($path, $mode); } ?> /**  * Makes directory and returns BOOL(TRUE) if exists OR made.  *  * @param  $path Path name  * @return bool  */ function rmkdir($path, $mode = 0755) { $path = rtrim(preg_replace(array("/\/", "//{2,}/"), "/", $path), "/"); $e = explode("/", ltrim($path, "/")); If(substr($path, 0, 1) == "/") {          $e[0] = "/".$e[0]; } $c = count($e); $cp = $e[0]; for($i = 1; $i < $c; $i++) { If(!is_dir($cp) && !@mkdir($cp, $mode)) {                  return false;          }           $cp .= "/".$e[$i]; } Return @mkdir($path, $mode); } ?>

Example 2

Somehow the recursive version of mkdir didn't work for me on Mac and the workaraounds listed

代码如下	复制代码
function mkdir_r($dirName, $rights=0777){ $dirs = explode('/', $dirName); $dir=''; foreach ($dirs as $part) { $dir.=$part.'/'; if (!is_dir($dir) && strlen($dir)>0)             mkdir($dir, $rights);     } } ?> Tested and works ;)

below alsow didn't work for me, so heres my solution:

The code is as follows	Copy code
function mkdir_r($dirName, $rights=0777){ $dirs = explode('/', $dirName); $dir=''; foreach ($dirs as $part) {           $dir.=$part.'/'; If (!is_dir($dir) && strlen($dir)>0)                  mkdir($dir, $rights); } } ?> Tested and works ;)

例3

    {

代码如下  代码如下 复制代码 function mkdirs($dir)     {         if(!is_dir($dir))         {             if(!mkdirs(dirname($dir))){                 return false;             }             if(!mkdir($dir,0777)){                 return false;             }         }         return true;     }     function rmdirs($dir)     {         $d = dir($dir);         while (false !== ($child = $d->read())){             if($child != '.' && $child != '..'){                 if(is_dir($dir.'/'.$child))                 rmdirs($dir.'/'.$child);                 else unlink($dir.'/'.$child);             }         }         $d->close();         rmdir($dir);     }

复制代码

function mkdirs($dir)

        if(!is_dir($dir))

        }     }     function rmdirs($dir)     {         $d = dir($dir);         while (false !== ($child = $d->read())){             if($child != '.' && $child != '..'){                 if(is_dir($dir.'/'.$child))                 rmdirs($dir.'/'.$child);                 else unlink($dir.'/'.$child);             }         }         $d->close();         rmdir($dir);     } 三个创建目录的函数都有自己的优点，这里我也没有一个个测试了，只使用了第二个感觉非常的不错。 http://www.bkjia.com/PHPjc/633126.htmlwww.bkjia.comtruehttp://www.bkjia.com/PHPjc/633126.htmlTechArticle在php中mkdir函数是创建目录它自身是不可以递归创建目录了，我们需要遍历进行目录然后调用mkdir即可，下面来看一下操作方法。 例 代码如...
