Converting a URL to hex

[ciber]

I am wanting to convert a URL to a specific format, what PHP function would I use.

 

This is what the URL looks like : http://www.amazon.com/

This is what I need it to be converted to: http%3A%2F%2Fwww.amazon.com%2F

 

Since it is used like this :: http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%2F

I dont know if there is a specific function for this but my best guess would be to do something like this..

 

<?php

$input = 'http://www.amazon.com/';

for ($i=0;$i<strlen($input);$i++) {
echo dechex(ord($input{$i}));
}

?>

 

Then filter out the chars you dont want to change..

It looks like you are replacing all the  / with %

 

$http = "THE Url You want to rewrite";

$rewrite_http = str_replace("/", "%", "$http");

echo $rewrite;

?? dude look closer, i ain't just changing the the / to %, if you notice '%2F' is the hex representation of '/'

sigh ... nevermind, function I was supposed to use was right, stupid me made a typo .. no wonder it was not working

WHY DO U NEED TO do that? why does it need to be converted? i have a get variable that contains a url i use for redirecting and it works just fine no converts needed

It hasn't been mentioned in this thread yet, but a function to do this is urlencode.

yeah i was thinking of the urlencode thing before i posted i just couldnt remember the name. i had to use it in a feed on a php page to encode the url that had like get variables in it and spaces whatnot.. to validate the feed.
