array(
  1 => array(
    0 => array(
      'created' => integer 1332383287
      'updated' => integer 1332385146
      'id' => string '30' (length=2)
      'level' => integer 10
      'tag_id' => integer 1
      'status' => integer 0
      'creator_uid' => integer 6
      'assign_uid' => integer 6
      'assign_history' => string '|6||6|6|' (length=8)
      'title' => string '[iBay365] ' (length=10)
      'context' => string '
               )
            )           
      )
//要求是 “1 => array(0=>array(... ...))” 这里的1 变成 php或者ajax等文字,之后再一次用dump()打印出来
//就变成了 “php => array(0=>array(... ...))”   请问用什么方法能办到,我想了半天实在想不出,手册也查了
//貌似没有这样的函数,往各位能帮忙,谢谢了
