URL Manipulation...

[SystemOverload]

PHP 5.2.5

 

I want to create a function to manipulate the current URL.

 

How is the best way to retrieve the separate parts of the URL to a variable. 

 

1 - "HTTP" or "HTTPS" etc

2 - www.domain.com

3 - directory/2nddirectory

4 - index.php

5 - id=10&mode=qv

 

I want to be able to insert and/or remove 'variables' to facilitate passing more information thru _GET

 

Thanks

the parse_url() function is exactly what you need. Example:

 

<?php

$url = 'http://username:password@hostname/path?arg=value#anchor';

print_r(parse_url($url));

?>

I'm sorry, I didn't make myself clear. How do I retrieve the seperate parts of the url, parse_url() is just a function, how do I get the URL itself into a variable so I can start manipulating it?

 

Thanks

Your asking about the URL your script resides at right?

 

Look at the superglobal $_SERVER  variable which holds various url/server data

http://us3.php.net/reserved.variables.server

 

print_r($_SERVER) to see whats in there.

 

That + parse_url() will get what you need

Trouble is _SERVER is an array and parse_url takes a string...

 

How do i get from _SERVER to "http://www.domain.com/dir1/dir2/something.php?id=1&mode=pwc"

 

Sorry for being a pain, lol

 

Thanks

you can get strings from the server array by accessing its index's with its keys. for example:

//the script name
$name = $_SERVER['SCRIPT_NAME'];
//request method (IE get or post)
$method = $_SERVER['REQUEST_METHOD'];
//the protocol (LIKE HTTP, HTTPS, etc.) 
//btw for HTTP it will return the version also, IE HTTP/1.1
$protocol = $_SERVER['SERVER_PROTOCOL'];
//query string, ie what the ?get=value part of the URL
$query = $_SERVER['QUERY_STRING'];

 

if you check out the manual it has all of them

ok, thanks for everyone's input, especially the last guy, upto the point where he posted, I didn't get exactly what i asked for... If you read my original request:

 

How is the best way to retrieve the separate parts of the URL to a variable. 

 

1 - "HTTP" or "HTTPS" etc

2 - www.domain.com

3 - directory/2nddirectory

4 - index.php

5 - id=10&mode=qv

 

Everyone except the last guy dropped titbits, but didn't give me exactly what I needed, finally I finished up with the following: 

(credit for the substr() bit goes to a random tutorial I found thru google)

 

$varQuery = "";
if (strlen($_SERVER['QUERY_STRING']) != 0) {$varQuery = "?";}
$varURL = 
substr($_SERVER['SERVER_PROTOCOL'],0,strpos($_SERVER['SERVER_PROTOCOL'],'/')) . "://" .  
$_SERVER["HTTP_HOST"] . 
$_SERVER['SCRIPT_NAME'] . $varQuery .
$_SERVER['QUERY_STRING'] ;

 

 

Thanks for everyones help.
