替换PHP变量中的部分URL

Question

I am using PHP to set the current URL as a variable using

$url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];

This would echo the string:

http://www.example.com/landing-page-demo/

I would like to replace the 'landing-page' part of the string with 'confirmation-page' and then save this updated URL as another variable.

I was thinking of using str replace, is this the most ideal method of doing this? Not sure how to approach the problem

Answer 1

Indeed, short of knowing regular expressions, str_replace will do the trick.

Perform str_replace on $_SERVER['REQUEST_URI']

Example:

$url = 'http://' . $_SERVER['SERVER_NAME'] . str_replace("landing", "confirmation", $_SERVER['REQUEST_URI']);
