PHP implementation of path suffix removal method

The path suffix refers to an identification symbol in a web page link or file path, usually in the form of a period "." and a suffix name, such as ".html", ". php" etc. In website development, sometimes we want to remove the suffix name in the path to achieve a more beautiful and friendly URL and improve search engine optimization. Below we will introduce how to use PHP to implement path suffix removal and provide specific code examples.

First of all, we can use some string processing functions and regular expressions in PHP to remove path suffixes. The following is a simple sample code:

<?php
// 获取当前网页的完整URL
$currentPageURL = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

// 去除路径后缀
$cleanURL = preg_replace('/.[^.]*$/', '', $currentPageURL);

// 输出去除后缀的URL
echo $cleanURL;
?>

In this code, we first obtain the complete URL of the current web page, and then use the preg_replace function and regular expressions to replace the last "." and The characters following it are removed, thereby realizing the deletion of the path suffix. The final output will be the URL with the suffix removed.

In addition to the above method, we can also remove the path suffix in other ways, such as using PHP's explode function and substr function. The following is another sample code:

<?php
// 获取当前网页的完整URL
$currentPageURL = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

// 按照"."分割URL
$parts = explode('.', $currentPageURL);

// 去除最后一个数组元素（即后缀名）
$cleanURL = substr($currentPageURL, 0, strrpos($currentPageURL, '.'));

// 输出去除后缀的URL
echo $cleanURL;
?>

Through this code, we have achieved a similar function. First, we use the explode function to split the URL into arrays according to ".", and then use the substr function and strrpos function to remove the suffix. Part other than the name, thus obtaining the URL with the path suffix removed.

To sum up, through the above two methods, we can relatively easily remove the path suffix. In actual applications, the appropriate method can be selected according to specific needs, and the code can be adjusted and optimized according to the situation.
