Title: Path suffix removal tool written in PHP

With the development of the Internet, the URL address of the website has become more and more important. Sometimes we encounter some URL addresses with suffixes, such as "http://www.example.com/page.php" or "http://www.example.com/page.html". These suffixes Not only does it appear verbose, but it may affect search engine optimization. Therefore, writing a path suffix removal tool becomes a necessary task.

In PHP programming, you can easily implement a path suffix removal tool. Below we introduce how to write such a tool and provide specific code examples.

First, we need to create a PHP file named "remove_suffix.php", in this file we will write our path suffix removal tool.

The code example is as follows:

<?php
function remove_suffix($url){
    $pathinfo = pathinfo($url);
    if(isset($pathinfo['extension'])){
        $url = str_replace('.' . $pathinfo['extension'], '', $url);
    }
    return $url;
}

// 测试示例
$url1 = "http://www.example.com/page.php";
$url2 = "http://www.example.com/page.html";

echo remove_suffix($url1) . "<br>";
echo remove_suffix($url2) . "<br>";
?>

In the above code example, we define a function named "remove_suffix", which receives a URL address as a parameter and utilizes PHP's built-in The function pathinfo obtains path information, then determines whether a suffix exists and deletes it, and finally returns the processed URL address.

In the test example, we passed in the URL address with suffix and without suffix respectively for testing. We can see that the suffix has been successfully removed in the result.

With this simple path suffix removal tool written in PHP, we can easily optimize the URL address and make the website look more concise and clear. This not only benefits the user experience, but also improves the website’s ranking in search engines.

Summary: PHP provides a wealth of built-in functions and syntax to handle string operations. Writing a path suffix removal tool can be completed in just a few lines of code. I hope that readers can have a deeper understanding of path processing in PHP and further improve their programming skills through the introduction and examples of this article.
