Question

here’s the code i’m using:

$from=urldecode($_GET['from']);
$str =urldecode("%2B");
echo "$str<br>";
echo "$from<br>";

and here’s part of the URL: from=%2B995594262653

why does this echo

+
 995594262653

? (note, there’s a space in front of the number).
i am using $str to check if the function works at all. apparently, it works for a simple %2B. What could be an issue?

Answer 1

It is working, but you need to realise that PHP will automatically urldecode the data it in puts in the $_GET array. You are doing it a second time and transforming the input even more.

When your script runs, $_GET['from'] contains [phone]

When you run that value through urldecode, the + gets transformed to a space.
