php-遍曆數組，根據mark值的不同，使資料顯示在不同的模組中

php遍曆json

有這樣一個數組$jobArr

$jobArr=array(  1 =>     array(      0 =>         array(          'name' =>  '產品經理1',          'desc' =>  '廣州' ,          'mark' =>  'group:1' ),      1 =>         array          ( 'name' =>  '產品經理1',           'desc' =>  '廣州' ,          'mark' =>  'group:1'),      2 =>         array          ( 'name' =>  '產品經理1',          'desc' =>  '廣州' ,          'mark' =>  'group:1') ),  2 =>     array (      0 =>         array (          'name' =>  '產品經理2' ,          'desc' =>  '廣州' ,          'mark' =>  'group:2'),      1 =>         array (          'name' =>  '產品經理2' ,          'desc' =>  '廣州' ,          'mark' =>  'group:2')),  3 =>     array (      0 =>         array (          'name' =>  '產品經理3' ,          'desc' =>  '廣州' ,          'mark' =>  'group:3' ),      1 =>         array (          'name' =>  '產品經理3' ,          'desc' =>  '廣州' ,          'mark' =>  'group:3')));

         if($jobArr[$index]){            foreach($jobArr[1] as $post){                $jobList2 .= <<                    {$post['name']}                    {$post['desc']}                html;        }            foreach($jobArr[2] as $post){                $jobList3 .= <<                {$post['name']}                {$post['desc']}            html;            }            foreach($jobArr[3] as $post){                $jobList4 .= <<                {$post['name']}                {$post['desc']}            html;            }        }

在這裡我遍曆了三次，然後放在這三個div中，很麻煩，怎麼遍曆一次就可以將資料分類放在這幾個div中呢？

 { $jobList2}   { $jobList3}     { $jobList4}
