php中mkdir函数递归创建目录(文件夹)

<?php
/**
 * 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);
}

?>

<?php
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 ;)

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);

    }

项目用到临时写的。待完善
