PHP uses the functions pathinfo(), parse_url() and basename() to parse URLs

As we all know, the functions pathinfo(), parse_url() and basename() in PHP are all functions for parsing URLs, but there are some differences. Some examples are listed below. It is easier to understand these three through examples. Friends in need can refer to the methods and techniques for using functions. Friends who are interested can learn together below.

This article mainly introduces the example code of php using the functions pathinfo(), parse_url() and basename(), as follows Without further ado, let’s look directly at the code

The example code is as follows:

1. Use pathinfo to parse the URL

<?
 $test = pathinfo("http://localhost/index.php");
 print_r($test);
?>

The results are as follows

Array
(
 [dirname] => http://localhost //url的路径
 [basename] => index.php //完整文件名
 [extension] => php //文件名后缀
 [filename] => index //文件名
)

2. Use the parse_url() function to parse

<?
 $test = parse_url("http://localhost/index.php?name=tank&sex=1#top");
 print_r($test);
?>

The results are as follows

Array
(
 [scheme] => http //使用什么协议
 [host] => localhost //主机名
 [path] => /index.php //路径
 [query] => name=tank&sex=1 // 所传的参数
 [fragment] => top //后面根的锚点
)

##3. Use basename() to parse

<?
 $test = basename("http://localhost/index.php?name=tank&sex=1#top");
