pclziputilpathinclusion

函数
pclziputilpathinclusion ( $p_dir, $p_path )

pclziputilpathinclusion: 这个函数检查一个路径是否在一个指定的目录内。它需要两个参数。$p_dir (string) 表示要检查的目录,$p_path (string) 表示要检查的路径。

function PclZipUtilPathInclusion($p_dir, $p_path)
  {
    $v_result = 1;

    }

      $p_path = PclZipUtilTranslateWinPath(getcwd(), FALSE).'/'.substr($p_path, 1);
    }

      }

        $v_result = 2;
      }
      else if ($i < $v_list_dir_size) {
        // ----- The path is shorter than the dir
        $v_result = 0;
      }
    }

    // ----- Return
