PHP_SELF, SCRIPT_NAME, REQUEST_URI difference, requesturi

$_SERVER[PHP_SELF], $_SERVER[SCRIPT_NAME], $_SERVER['REQUEST_URI'] are very similar in usage. They all return information related to the page address currently being used. Here are some Relevant examples to help determine which ones are best suited in your script.

$_SERVER['PHP_SELF']

Copy code The code is as follows:

http://www.yoursite.com/example/ — – — /example/index.php
http://www.yoursite.com/example/index.php — – — /example/index.php
http://www.yoursite.com/example/index.php?a=test — – — /example/index.php
http://www.yoursite.com/example/index.php/dir/test — – — /dir/test

When we use $_SERVER['PHP_SELF'], no matter whether the accessed URL address has index.php, it will automatically return index.php. But if a slash is added after the file name, it will Return all subsequent content in $_SERVER['PHP_SELF'].

$_SERVER['REQUEST_URI']

Copy code The code is as follows:

http://www.yoursite.com/example/ — – — /
http://www.yoursite.com/example/index.php — – — /example/index.php
http://www.yoursite.com/example/index.php?a=test — – — /example/index.php?a=test
http://www.yoursite.com/example/index.php/dir/test — – — /example/index.php/dir/test

$_SERVER['REQUEST_URI'] returns the exact address we wrote in the URL. If the URL only writes "/", it returns "/"

$_SERVER['SCRIPT_NAME']

Copy code The code is as follows:

http://www.yoursite.com/example/ — – — /example/index.php
http://www.yoursite.com/example/index.php — – — /example/index.php
http://www.yoursite.com/example/index.php — – — /example/index.php
http://www.yoursite.com/example/index.php/dir/test — – — /example/index.php

The current file name/example/index.php is returned in all returns
