Question

Using e-mail for login, I figured out that there are (probably) problems with the charset of the HTML-form…

At the very top of the document I use php for:

header('Content-type: text/html; charset=utf-8');

In the head-section I also have:

<meta charset="UTF-8">

and even in the form itself:

<form accept-charset="utf-8" ...>

However, when serializing the form the e-mail address is being return as follows:

email=my%40email.com

Does anybody have an idea why?

Answer 1

Yes, CoursesWeb is right with this. Use urldecode($_POST['email']); and it will automatically decode the string with all %## in it.

From php.net:

string urldecode ( string $str ) Decodes any %## encoding in the given
string. Plus symbols (‘+’) are decoded to a space character.
