Php 需要匹配此示例中的所有单词变体

这将标记单词

博彩

，

赌博

，

xxx

，但不会标记

博彩

，

赌博

，

xxx

我希望它能够标记这些单词的所有变体（即：下注、下注、下注等）。显然，我可以单独列出它们，但我希望以某种方式匹配它们，以便标记这些单词的所有变体

$original  = $_POST['message'];

$spamw = array('betting', 'gambling', 'xxx');

foreach ($spamw as $num) {
    if (( $pos = strpos( $original, $num )) !== false) { 
        $err = 'Something went wrong. Please, try again.';
    }
}

SOLOVED

$spamw = array('betting', 'gambling', 'xxx');
$original = $_POST['message'];

foreach ($spamw as $spamwords) {
  if (preg_match("/\b$spamwords\b/i", $original)) {
$err = 'Something went wrong. Please, try again.';
  }
}

好的，我用脑海中所有变化的0.1%更新解决方案：

<?php
function tospam($dictswrd){
    global $word;
    print('the imput is <span style="color:red">'.$word.'</span> compare to <span style="color:blue">'.$dictswrd.'</span> from Dictionary<br>');
    $pattern = '/(?<!\p{L})'.strtolower($word).'*/iu';
    return preg_match($pattern,$dictswrd ) >0;
}




$dictionary = array('betting', 'gambling', 'xxx'); //a small internal database loaded from a internal file maybe file?
/*
 eg:
$dictionary =file('spam_dictionary.txt');
internal you can drop a file 
spam_dictionary.txt :
---------------
betting
gambling
xxx
---------------
or you can fill the array of dictionary from a kind of database=any kind
*/

if(isset($_POST['message'])){
    print('<h1>FORM`s POST method 1</h1>');

    $word=$_POST['message'];//let's say that's coming from input from post

一种方法是像现在这样将
$spamw
数组中的所有单词存储为小写，然后使用PHP
strtolower（）
函数将任何用户输入转换为小写字符。然后，您的PHP脚本可以将用户输入与存储在
$spamw
数组中的值进行比较，检查是否有任何单词匹配。
只需使用函数，该函数将查找不区分大小写的子字符串第一次出现的位置，请看，这只是您想要捕捉的案例差异，而不是
strpos
？将
strpos
更改为
stripos
@MrK ok
i
wink-wink仍然认为你应该在preg_-match上要求一个不区分大小写的选项。顺便说一句，我的问题不同（对于在另一个线程中标记为已回答的人）。在我的例子中，$_POST['message']是由用户提交的，可能有各种各样的变体（以及其他垃圾邮件）。我需要知道在我现有的示例中可以做些什么来匹配它们，即使我的数组中的所有垃圾邮件都是小写的。U hv将所有内容都存储为小写。为什么不将用户的输入转换为小写，然后进行比较P不确定这对我原来的问题有何帮助。我会回来看preg_match示例我做了更新。我会发布此消息，以防您无法收到我修改解决方案最简单的解决方案是：$spamw=array（'Botting'，'Bogging'，'xxx'）$原始=$_POST['message']；foreach（$spamwords$spamwords）{if（preg_match（“/\b$spamwords\b/i，$original））{$err='出了点问题，请再试一次。；}}你的意思是：$original=strtolower（'$_POST[message]'）；谢谢@jamiemgg$original=strtolower（$_POST['message']）；这正是我所需要的。是的，像这样的东西可能对你想要完成的事情有用。如果您愿意，您甚至可以创建另一个变量来存储转换为小写的文本，前提是它有助于保持组织。
