+符号没有进入php GET变量从url读取[重复]

Question

This question already has an answer here:

• Is it possible to preserve plus signs in PHP $_GET vars without encoding? 7 answers

I am retrieving a GET variable from URL which contains "+" in between the string. But PHP is storing "space" instead of "+"

PFB output :

in URL : key=7VR47WOtmD+acS0  
php echo : echo rawurlencode$_GET['key']) ;
//returns 
7VR47WOtmD acS0

Could you please tell me how to get + symbol in the php output ?

Note: do not suggest find and replace option

You need to encode reserved characters ($ & + / : ; ? @ etc) if you want to use them in an URL. You need to use %2B instead of +. If you're using PHP to generate the URL, then you can use the function urlencode() to automatically encode all characters that require encoding.
