何不嘗試自己封裝array_filter

function user_array_filter($array = array(), $callback = null) {
    $args = func_get_args();
    if( count($args) < 2 ) {
        exit('Missing arguments for user_array_filter, two arguments at least');
    }
    if( count($args) == 2 ) {
        foreach( $array as $k => $v ) {
            $result = $callback($v);
            if( !$result ) {
                return false;
            }
        }
    } else {
        $limit = $args[2];
        foreach( $array as $k => $v ) {
            $result = $callback($v, $limit);
            if( !$result ) {
                return false;
            }
        }
    }
    return true;
}

function myGt($val, $limit = 88){
    if ($val >= $limit)
        return true;
    return false;
}

自己寫一個函數(shù)

function filter_by_value ($array, $min) 
{ 
    if(is_array($array) && count($array)>0)  
    { 
        foreach($array as $key => $value) 
        { 
            if($value > $min)
            {
                $newarray[$key] = $value;  
            }
        } 
    } 
      return $newarray; 
} 
    
$arr = [10,78,91,101,410,7,36];
print_r(filter_by_value($arr,88));

你看下函數(shù)手冊

自定義數(shù)組過濾
