是要这个效果吗？
php$jobarr=array( 1 => array( 0 => array( 'name' => '产品经理1', 'desc' => '广州' , 'mark' => 'group:1' ), 1 => array ( 'name' => '产品经理1', 'desc' => '广州' , 'mark' => 'group:1'), 2 => array ( 'name' => '产品经理1', 'desc' => '广州' , 'mark' => 'group:1') ), 2 => array ( 0 => array ( 'name' => '产品经理2' , 'desc' => '广州' , 'mark' => 'group:2'), 1 => array ( 'name' => '产品经理2' , 'desc' => '广州' , 'mark' => 'group:2')), 3 => array ( 0 => array ( 'name' => '产品经理3' , 'desc' => '广州' , 'mark' => 'group:3' ), 1 => array ( 'name' => '产品经理3' , 'desc' => '广州' , 'mark' => 'group:3')));foreach($jobarr as $k=>$v){ $html=array(); foreach($v as $key=>$val){ $html[$val['mark']]['html'].={$val['name']}{$val['salary']}; } $div.=.$html[$val['mark']]['html'].
