php unset从数组中删除某些条目(使用正则表达式)？

自定义函数

/**
 * 删除一维数组里的多个key
 * $isRegular 是否启用正则 1是，0否;$keys='/goodsNo\_(.*)/'
 */
function ZHTUnset(&$data,$keys,$isRegular=0){
  if($keys!='' && is_array($data)){
		if($isRegular == 1){ // 正则
			foreach ($data as $key=>$v){
					$res = preg_match($keys, $key);
					if($res){
						unset($data[$key]);
					}
			}
		}else{
			$key = explode(',',$keys);
			foreach ($key as $v)unset($data[$v]);
		}    
  }
}

$data = ['abc'=>1,'cc'=>2,'goodsNo_123'=>3,'goodsNo_124'=>4];
    $keys='/goodsNo\_(.*)/';
    ZHTUnset($data,$keys,1);
    dump($data);
    die;
