Okay to Urlencode() Entire URL?

[partypete]

Hello all,

I want to pass a url from one page to another and simply want to know if I can urlencode() an entire url. I've done some searching on the net and some say not to do so.(I'm pretty sure it actually is okay....)

So let's say I want to pass page1.php's URI to page2.php.

Using $_SERVER['REQUEST_URI'] I get page1.php's URI as seen below:

/people/profiles/profiles.php?pageNum_rs_profiles=1&totalRows_rs_profiles=13&searchInfo=johnny&do_search=Find

If I want to pass the above URI to page2.php, is this the proper way to do so?(Using urlencode to encode the entire above URI...)

<a href="http://www.domain.com/page2.php?returnto=<?php echo urlencode($_SERVER['REQUEST_URI']); ?>">Link Text</a>

Would this also work fine for a complete URI such as:

http://www.domain.com/people/profiles/profiles.php?pageNum_rs_profiles=1&totalRows_rs_profiles=13&searchInfo=johnny&do_search=Find

Thanks as always!
Peter

Since you don't want bits of page1.php's URL to be confused with bits of the URL you're embedding it in, you'll need to urlencode the whole thing.

As far as the link you're constructing is concerned it's just a string like any other; the fact that it happens to be interpretable as a URI is irrelevant (and you don't want it to be interpreted as a URI here anyway, or things will get confused).
