PHP-preg_match-如何将字符串的大写/小写与之前或之后的内容进行匹配? [英] PHP - preg_match - How to match a string upper/lower case with anything before or after it?

问题描述

我有一部分函数是这样的:

I have a part of a function that goes like this:

if (preg_match("#\bscript\b#",$userInput))
{
    $bannedWord = 'script';
    logHax();
    return TRUE;
}

这给我要完成的工作造成了问题，因为它只会匹配确切的单词"script"，而不会匹配它的变体，例如"ScriPt"或"<script>".

This is causing a problem for what I am trying to accomplish because it will only match the exact word "script" and not variations of it, like "ScriPt" or "<script>".

我想要的是不匹配的字符串以及原始字符串返回true的示例.

What I would like to have is the examples of the not matched strings along with the original string return true.

有人可以让我对这件事有一些了解.

Could someone provide me with a bit of understanding on this matter.

也将不胜感激任何涵盖此类内容的教程，

Also any tutorials that cover something like this would be greatly appreciated,

谢谢！

推荐答案

这是怎么回事:

if (preg_match("/<script\b[^>]*>/i",$userInput))
{
    $bannedWord = 'script';
    logHax();
    return TRUE;
}
