help getting parameters correctly from url

[blic]

Hi all,

 

I need to get a parameter from an url, but the GET variables are passed through urldecode().

Some of my variables may have characters such as "+", ":", spaces, etc.

When I use GET, all "+" are converted to spaces. I can use urlencode to get the "+" back, but also everything that was previously a space also turns into "+".

Example:

variable = abc+ c+

 

Then I can get either:

abc c

or

abc++c+

 

but I want to get abc+ c+

 

 

Would anybody know how to help me?

 

Thanks!

urldecode() + $_GET = Bad

_GET does urldecode automatically..

I do enconde, in order to get the "+", but all original spaces also becomes "+"

that's my problem. I want to get the original "+" as well as the spaces

[sasa]

use urlencode() function on variable before put it in link and urldecode() on $_GET variable

[QuickOldCar]

Or alternately can use

http://us.php.net/rawurldecode

and

http://php.net/manual/en/function.rawurlencode.php

 

example:

<?php
$url = "http://somesite.com/My File/script.php?value=1+2+3+4";
$decode = rawurldecode($url);
$encode = rawurlencode($decode);

echo $url."<br />";
echo $decode."<br />";
echo $encode."<br />";
?>

thanks for the reply..

I know it works when there's only +

But when there's + and spaces is when it get's confused..

Try the same example but instead of value=1+2+3+4

try value=1+2 +3+4

the space after "2" is the one I can't get..

try

<?php
$a='sasa + sasa';
echo '<a href="?data='. urlencode($a).'">click me</a>'."<br />\n";
if (isset ($_GET)) echo $_GET['data'];
?>

script just generate link with + and space, and echo result
