一、php正则去除js
使用 PHP 正则表达式去除 JavaScript 代码
JavaScript code can be embedded within content using <script> tags or inline event handlers. While JavaScript is a powerful tool for adding interactivity to web pages, it can also pose security risks if not properly sanitized. In PHP, it is common to use regular expressions to remove JavaScript code from content before displaying it on the web.
使用 preg_replace 函数进行正则匹配
PHP provides the preg_replace function, which can be used to perform regular expression search and replace operations. By crafting an appropriate regular expression pattern, we can target JavaScript code within HTML content and replace it with an empty string. Let's take a look at a simple example to demonstrate this process.
This is some sample text with <script>alert('Hello, World!');</script> embedded JavaScript code.
