in_array — 检查数组中是否存在某个值.用递归来检验多维数组array(2) {
[0]=>
array(1) {
["bankcard"]=>
string(19) "6212260200176770626"
}
[1]=>
array(1) {

}$aa = 6217002430037113726;$att = $g_att;

public function deep_in_array($value, $array) {    foreach($array as $item) {        if(!is_array($item)) {            if ($item == $value) {                return true;            } else {                continue;            }        }        if(in_array($value, $item)) {            return true;        } else if($this->deep_in_array($value, $item)) {            return true;        }    }   return false;}
