php去除二维数组中重复值程序

function my_array_unique($array2D){

foreach ($array2D as $v){
$v = implode(“,”,$v);
$temp[] = $v;
}
$temp = array_unique($temp);
foreach ($temp as $k => $v){
$temp[$k] = explode(“,”,$v);
}
return $temp;
}

function a_array_unique($array)//写的比较好
{
$out = array();
foreach ($array as $key=>$value) {
if (!in_array($value, $out))
{
$out[$key] = $value;
}
}
return $out;
}

$array2D = array(‘first’=>array(‘title’=>’1111′,’date’=>’2222′),’second’=>array(‘title’=>’1111′,’date’=>’2222′),’third’=>array(‘title’=>’2222′,’date’=>’3333′));

$as = a_array_unique($array2D);
print_r($as);
