PHP 两个二维数组求不同

    public function arrcha(){

        $arr1[0] = [
            'id'=>1,
            'name'=>'name',
        ];
        $arr1[1] = [
            'id'=>2,
            'name'=>'name2',
        ];
        $arr1[2] = [
            'id'=>3,
            'name'=>'name3',
        ];
        $arr1[3] = [
            'id'=>4,
            'name'=>'name4',
        ];
        $arr2[0] = [
            'id'=>2,
            'name'=>'name2',
        ];
        $arr2[1] = [
            'id'=>3,
            'name'=>'name3',
        ];
        $arr3=array();
        foreach ($arr1 as $key => $value) {
            if(!in_array($value,$arr2)){
                $arr3[]=$value;
            }
        }
        var_dump($arr3);
    }
}
