本文以实例形式说明了php建立多层级目录的实现方法,代码简洁实用,功能强大,对于php程序员来说有一定的参考借鉴价值。实例详情如下:

/**
 *根据路径path建立多级目录
 *$dir目标目录 $mode权限,0700表示最高权限
*/
function makedir( $dir , $mode = "0700" ) {
  if(strpos($dir , "/" )){
    $dir_path = "" ;
    $dir_info = explode ( "/" , $dir );
    foreach($dir_info  as  $key => $value ){
      $dir_path .= $value ;
      if (!file_exists($dir_path )){
        @mkdir ( $dir_path , $mode ) or  die ( "建立文件夹时失败了" );
        @chmod ( $dir_path , $mode );
      } else {
        $dir_path .= "/" ;
 continue ;
 }
      $dir_path .= "/" ;
    }
    return $dir_path ;
  } else {
 @mkdir( $dir , $mode ) or die( "建立失败了,请检查权限" );
    @chmod ( $dir , $mode );
    return $dir ;
  }
} //end makedir
makedir( "0/1/2/3/" );
Copy after login
