遍历数组，根据mark值的不同，使数据显示在不同的模块中

<code>//有这样一个数组$jobArr
$jobArr=array(
  1 => 
    array(
      0 => 
        array(
          'name' =>  '产品经理1',
          'desc' =>  '广州' ,
          'mark' =>  'group:1' ),
      1 => 
        array 
         ( 'name' =>  '产品经理1', 
          'desc' =>  '广州' ,
          'mark' =>  'group:1'),
      2 => 
        array 
         ( 'name' =>  '产品经理1',
          'desc' =>  '广州' ,
          'mark' =>  'group:1') ),
  2 =>

是要这个效果吗？

<code>php</code><code>$jobArr=array(
  1 => 
    array(
      0 => 
        array(

          'mark' =>  'group:1' ),
      1 => 
        array 
         ( 'name' =>  '产品经理1', 
          'desc' =>  '广州' ,
          'mark' =>  'group:1'),
      2 => 
        array 
         ( 'name' =>  '产品经理1',
