致命错误:未被捕获的TypeError:filter_var():参数3($ options)必须为数组类型 [英] Fatal error: Uncaught TypeError: filter_var(): Argument #3 ($options) must be of type array
本文介绍了致命错误:未被捕获的TypeError:filter_var():参数3($ options)必须为数组类型的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
上一个问题: get_magic_quotes_gpc()返回在我的代码中未定义
那么那么..
我解决了以下问题:
致命错误:无法声明类CI_Log，因为该名称已在第27行(第27行)的D:\ xampp \ htdocs \ system \ libraries \ Log.php中使用，类CI_Log { 通过这种方式:
/***错误记录界面**我们使用它作为一种简单的机制来访问日志记录*类并发送要记录的消息.** @公开访问* @返回无效*/如果(！function_exists('log_message')){函数log_message($ level ='error'，$ message，$ php_error = FALSE){静态$ _log;如果(config_item('log_threshold')== 1){返回;}$ _log =&load_class('Log');$ _log-> write_log($ level，$ message，$ php_error);}} 我改变了
"如果(config_item('log_threshold')== 0)" 到
"如果(config_item('log_threshold')== 1)" Common.php 文件内
在
<代码> D:\ xampp \ htdocs \ system \ core \ Common.php
但是现在有新的错误.

解决方案
将switch语句的默认部分更改为以下内容可以解决该问题:
开关($ which){案例"ipv4":$ flag = FILTER_FLAG_IPV4;休息;案例"ipv6":$ flag = FILTER_FLAG_IPV6;休息;默认:$ flag = FILTER_DEFAULT;休息;} 似乎它必须是旧版本的CodeIgniter中的错误.在默认"中，对于switch语句，它会将一个空字符串作为第三个参数传递给 filter_var ，但它必须接收一个 array 或 int .
它可能只是开始在PHP 8上引起致命错误，因为8引入了混合类型的类型提示: https://www.php.net/manual/en/language.types.declarations.php
mixed等效于联合类型array | bool | callable | int | float | object | resource | string | null.自PHP 8.0.0起可用.
使用此工具，您可以看到不同版本的PHP上发生了什么: https://3v4l.org/Sd6oS
编辑-可能无法修复所有您的错误，但最好是首先克服该错误，然后看看您留下的内容.
previous question: get_magic_quotes_gpc() returns undefined in my code
So then..
I fixed the problem of:
Fatal error: Cannot declare class CI_Log, because the name is already in use in D:\xampp\htdocs\system\libraries\Log.php on line 27 (line 27) class CI_Log {
In this way:
/**
* Error Logging Interface
*
* We use this as a simple mechanism to access the logging
* class and send messages to be logged.
*
* @access public
* @return void
*/
if ( ! function_exists('log_message'))
{
function log_message($level = 'error', $message, $php_error = FALSE)
{
static $_log;
if (config_item('log_threshold') == 1)
{
return;
}
$_log =& load_class('Log');
$_log->write_log($level, $message, $php_error);
}
}
I changed
"if (config_item ('log_threshold') == 0)"
to
"if (config_item ('log_threshold') == 1)"
inside the Common.php file
in
D:\xampp\htdocs\system\core\Common.php
but now there are new errors..

I'm not an experienced programmer, I'm a novice.
I fixed something by intuition, because intuition is my dominant skill, but intuition can help me up to a certain point, I need the experience and knowledge of those who know more than me, not only for fix this problem, but also to improve myself, it would be really appreciated if someone is kind enough to help me out of this flood of bugs to restore my site, thank you..
解决方案
Changing the default part of the switch statement to the following should resolve it:
switch ($which) {
case 'ipv4':
$flag = FILTER_FLAG_IPV4;
break;
case 'ipv6':
$flag = FILTER_FLAG_IPV6;
break;
default:
$flag = FILTER_DEFAULT;
break;
}
Seems it must be a bug in an old version of CodeIgniter. In the "default" case of the switch statement, it's passing an empty string as the 3rd argument to filter_var but it has to receive an array or int.
It's probably only started causing a fatal error on PHP 8 because 8 introduced type hinting for mixed types: https://www.php.net/manual/en/language.types.declarations.php
mixed is equivalent to the union type array|bool|callable|int|float |object|resource|string|null . Available as of PHP 8.0.0.
You can see what's happening on the different versions of PHP using this tool: https://3v4l.org/Sd6oS
EDIT - that probably won't fix all your errors but may be best to get past that one first and see what you're left with.
