php遍历json
有这样一个数组$jobArr
<code>$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 => array ( 0 => array ( 'name' => '产品经理2' , 'desc' => '广州' , 'mark' => 'group:2'), 1 => array ( 'name' => '产品经理2' , 'desc' => '广州' , 'mark' => 'group:2')), 3 => array ( 0 => array ( 'name' => '产品经理3' , 'desc' => '广州' , 'mark' => 'group:3' ), 1 => array ( 'name' => '产品经理3' , 'desc' => '广州' , 'mark' => 'group:3')));</code>
<code> if($jobArr[$index]){ foreach($jobArr[1] as $post){ $jobList2 .= <a class="post post2">{$post['name']}</a> <span class="salary">{$post['desc']}</span> html; } foreach($jobArr[2] as $post){ $jobList3 .= <a class="post post2">{$post['name']}</a> <span class="salary">{$post['desc']}</span> html; } foreach($jobArr[3] as $post){ $jobList4 .= <a class="post post2">{$post['name']}</a> <span class="salary">{$post['desc']}</span> html; } }</code>在这里我遍历了三次，然后放在这三个div中，很麻烦，怎么遍历一次就可以将数据分类放在这几个div中呢？
<code> <div1>{ $jobList2} <div2>{ $jobList3} <div3>{ $jobList4}</div3></div2></div1></code>
