Is it possible to save plus signs in PHP $ _GET without encoding?

Let's say I request this url:

http://mydomain.com/script.php?var=2+2

$ _ GET ['var'] will now be: "2 2", where should be "2 + 2"

Obviously, I could encode the data before sending it and then decode it, but I wonder if this is the only solution. I could also replace spaces with plus characters, but I want to allow spaces as well. I just want any characters to be transmitted without any decryption or url encoding. Thank!

preg_match_all('/(\w+)=([^&]+)/', $_SERVER["QUERY_STRING"], $pairs);
$_GET = array_combine($pairs[1], $pairs[2]);

( - % xx. .)

if(strpos($_SERVER["QUERY_STRING"], "+") !== false){
    $_SERVER["QUERY_STRING"] = str_replace("+", "%2B", $_SERVER["QUERY_STRING"]);
    parse_str($_SERVER["QUERY_STRING"], $_GET);

  • Just replace your request parameter plus (+) with the character "% 2B" in the URL before requesting the URL.

  • Now you just get the query parameter. This will automatically replace "% 2B" with a plus sign.

I just used the urlencode()URL to encode correctly and urldecode($_Get())to use the string again.
