除了上面提到的\\u剧作家通过链接WordPress Codex, 还有一个非常有用的本机PHP函数，允许您一次性清理来自$\\u POST super global的所有数据：filter_input_array. 看见php docs. 示例：

// let\'s say I\'m expecting to get data like this:
$_POST = [
    \'myString\'         => \'Hello World\',
    \'myInteger\'        => 42,
    \'myArrayOfStrings\' => [
        \'hello\',
        \'world\',
    ],
];

// sanitizing $_POST super global:

$data = filter_input_array( INPUT_POST, [
    \'myString\'         => FILTER_SANITIZE_STRING,
    \'myInteger\'        => FILTER_VALIDATE_INT,
    \'myArrayOfStrings\' => [
        \'filter\' => FILTER_SANITIZE_STRING,
        \'flags\'  => FILTER_REQUIRE_ARRAY,
    ],
] );

// now $data contains array of sanitized values
