Question

我不确定strpos()是否适合用于此目的任务。

问题：

如果用户在我的垃圾邮件变量中输入仇恨或其他字符串它返回正确的垃圾邮件过滤器消息，但如果是用户输入垃圾邮件变量与任何不在其中的字符串混合通过处理。

我希望输入从第一个字符串检查到最后一个字符串并且那个t不包含任何垃圾邮件变量字符串返回过程，这是我的代码

<?php
    //messgae
    error_reporting(E_ALL ^ E_NOTICE);
    $msg = array(); 
    $spam = "hate partisan party kill maim murder violence love sex fight beat assasinate thug steal sell bribe protest baricade bullets militia fear ";
    $spam_array = explode(" ",$spam);

    $check = strpos($spam, $_POST['message']);

         if ($check == true) {
        //do nothing
        $msg['invalid'] =  'Spam filter test didnt allow your message';

       } else {

        $msg['valid'] = 'process';   
       }


    if(isset($_POST['send'])){

      $message= $_POST['message']; 
    }

     ?>

    <?php 
    if (isset($msg)) {
    echo '<ul>';
    foreach ($msg as $alert) {
    echo "<li class='warning'>$alert</li>\n";
    }
    echo '</ul>';
    }?>
    <form action="" method="post">

Answer 1

你用$spam_array在那里开始了。他们检查它，你检查你的消息中是否找到了确切的坏词。

同时stripos代替strpos，以便它不区分大小写。

$spam = "hate partisan party kill maim murder violence love sex fight beat assasinate thug steal sell bribe protest baricade bullets militia fear ";
$spam_array = explode(" ",$spam);
$isSpam = isSpam($_POST['message'], $spam_array);


function isSpam($content, $spamList)
{
    foreach($spamList as $badWord) {
        if(stripos($content, $badWord) !== false) {
            return true;
        }
    }

    return false;
}

您需要使用字边界来改进您的支票，否则您会对像＆＃34;手套＆＃34;等字词产生误报。（爱）和＆＃34; Essex＆＃34; （性别）。您还应该使其不区分大小写。

以下方法（check函数）在查找每个＆＃34;垃圾邮件字时使用带有字边界元字符的preg_match＆＃34;在消息中。 i修饰符也使其不区分大小写：

function check($msg, $spam_array) {
    foreach ($spam_array as $spam_word) {
        if (preg_match("/\b" . $spam_word ."\b/i", $msg)) {
            return false;
        }
    }
    return true;
}

function test($msg, $spam_array) {
    echo "$msg => ", check($msg, $spam_array) ? 'OK' : 'not OK', PHP_EOL;
}

$spam = "hate partisan party kill maim murder violence love sex fight beat "
    . "assasinate thug steal sell bribe protest baricade bullets militia fear";
$spam_array = explode(" ", $spam);

test("I'm known for my cookie munching skills.", $spam_array);
test("I could kill for some cookies right now!", $spam_array);

输出：

I'm known for my cookie munching skills. => OK
I could kill for some cookies right now! => not OK
