Quickly remove suffix from URL path with PHP

In web development, we often encounter situations where URL paths need to be processed. In practical applications, sometimes we need to quickly remove the suffix in the URL path to keep the URL concise and clean. As a commonly used server-side scripting language, PHP provides many methods to manipulate URL paths. The following will introduce how to quickly remove the suffix of URL paths and provide specific code examples.

In PHP, we can use the pathinfo() function to obtain the information in the URL path, including the file name and suffix. Through this function, we can quickly remove the suffix of the URL path. Here is a simple sample code:

$url = "http://www.example.com/page.php";

// 获取URL的路径部分
$path = parse_url($url, PHP_URL_PATH);

// 使用pathinfo函数获取路径信息
$path_parts = pathinfo($path);

// 去除后缀
$filename = $path_parts['filename'];

// 输出结果
echo $filename;

In this code, we first use the parse_url() function to get the path part of the URL, and then use pathinfo()The function obtains path information, including file name and suffix. Finally, by accessing the filename key value in the array, you can get the URL path without the suffix.

In addition to using the pathinfo() function, we can also use regular expressions to quickly remove the suffix of the URL path. Here is another sample code:

$url = "http://www.example.com/page.php";

// 去除后缀
$filename = preg_replace('/.[^.]*$/', '', basename($url));

// 输出结果
echo $filename;

In this code, we use the preg_replace() function combined with a regular expression to match and replace the suffix part in the URL path. '/.[^.]*$/' means matching the last dot (.) to the end of the string, and then using the basename() function to get the file name part, and finally To achieve the purpose of removing the suffix.

In general, PHP provides a variety of methods to quickly remove the suffix of the URL path, and developers can choose the appropriate method according to actual needs. In actual development, keeping URL paths simple and clean is a good habit, which helps improve user experience and SEO optimization. I hope the above code examples can help readers better understand and apply.
