Rewriting URL's from a PHP Redirection - php

Question

How can i rewrite this url:
http://localhost/?=register
To look like this?:
http://localhost/index.php/Register

Answer 1

Your redirection code:
header('Location: /index.php/Register/',true,302);
exit;
For accessing the /Register/ value, use:
$_SERVER['PATH_INFO']

Answer 2

After performing the redirection using the header command, you must remember to write your code to process that URL.
/index.php/Register will try to load a "Register" file inside "/index.php/" folder ... 404 error
So you will need to use apache modrewrite to redirect these "virtual folders" to a centralized script that can handle it.
Something like this on .htaccess:
RewriteEngine on
RewriteRule ^index.php/(.*)$ index.php
Then, at your index.php, you will treat the incomming URL to detect that file, and do whatever you want with it.
I usually work with a catch-all (redirects everything to /index.php) and then break the URL and treat it, so I can have any number of virtual folder/files. Here is my own function to treat any incoming request:
function extractUri($uri="") {
if ($uri == "") $uri = isset($_SERVER['REQUEST_URI']) && $_SERVER['REQUEST_URI'] != "" ? $_SERVER['REQUEST_URI'] : "";
if ($uri != "") {
# removes query from request
if ($uri[0] != "/") $uri = "/".$uri; # ALWAYS START WITH /
$uri = explode("?",$uri);
$uri = str_replace("..",".",array_shift($uri)); # little exploit remover
$uri = explode("/",str_replace("//","/",$uri));
} else
$uri = array("/");
$context = array();
foreach ($uri as $part)
array_push($context,preg_replace("/(\.){2,}/","\.",$part)); # prevents ..
$action = array_pop($context); # file (with extension)
$original_action = $action; # preserve the original file with extension (I work w/o them)
$ext = "";
if ($action == "") $action = 'index'; # so if you are accessing folder/, then you probably want the index
else if (strpos($action,".")!==false) { # remove extension
$action = explode(".",$action);
$ext = array_pop($action);
$action = implode(".",$action);
$action = removeSimbols($action,true,false); # makes sure it is a valid filename, this function removes any weird character
}
return array($context,$action,$original_action,$ext); # returns the folder structure (array), the page/action, the page/action with extension, and said extension (lots of repetition to speed up later)
}
so extractUri("/index.php/Register") would return:
Array ([0] => "/", [1] => "index.php"), "Register", "Register", ""
