二维数组判断值雷同

二维数组判断值相同
$array = array(array('pid'=>1,'name'=>a),array('pid'=>2,'name'=>b),array('pid'=>3,'name'=>c),array('pid'=>1,'name'=>a),array('pid'=>4,'name'=>d));
类似这样的二维数组，怎样判断pid和name同时相等的值(如例子里的('pid'=>1,'name'=>a)值一样)
有的话就退出

[解决办法]

PHP code

$array = array(      array('pid'=>1,'name'=>'a'),      array('pid'=>2,'name'=>'b'),      array('pid'=>3,'name'=>'c'),      array('pid'=>1,'name'=>'a'));$tmp=array();foreach($array as $k=>$v){       if(!$tem[$v[pid].'_'.$v[name]]){              $tem[$v[pid].'_'.$v[name]]=$v;              print_r($v);        }else{                exit;                }        }

PHP code
$array = array(    array('pid' => 1, 'name' => 'a'),    array('pid' => 2, 'name' => 'b'),    array('pid' => 3, 'name' => 'c'),    array('pid' => 4, 'name' => 'd'),    array('pid' => 5, 'name' => 'e'),    array('pid' => 1, 'name' => 'a'),    array('pid' => 4, 'name' => 'd'));$idList = array();foreach ($array as $key => $value) {    $idList[] = implode(',', $value);}$idList2 = array_diff_assoc($idList, array_unique($idList));foreach ($idList2 as $key => $value) {    $akey = array_search($value, $idList);    echo '重复数组:';    print_r($array[$akey]);}
