Question

I wrote a function to strip parameters from urls, the function looks like this

function remove_it($c_link){

        $regex = array();
        $award = array();

        $regex[] = '/[\?&](?<name>sa)=(?<value>[^&=]+)/';
        $regex[] = '/[\?&](?<name>ei)=(?<value>[^&=]+)/';
        $regex[] = '/[\?&](?<name>ved)=(?<value>[^&=]+)/';
        $regex[] = '/[\?&](?<name>usg)=(?<value>[^&=]+)/';

        foreach($regex as $remove){

            $c_link = preg_replace($remove,'',$c_link);

        }

        return $c_link;

    }

When I use a testurl like this

$test = 'http://forum.gofeminin.de/forum/dietetique/__f2955_dietetique-Diatpillen.html&sa=U&ei=8doOUa6HOsfKtAaDpICIBQ&ved=0CB0QFjAA&usg=AFQjCNEcFS48QvteNkSNcszXv5RG6VUe2g';

It’s woking perfect. Now I wanted to use it in my code. So I called to function with my data and it doesn’t affect the string. I used print_r to see if the string looks strange, but it’s just 1:1 like in $test

$TEST-> http://forum.gofeminin.de/forum/dietetique/__f2955_dietetique-Diatpillen.html&sa=U&ei=C9wOUZuvCoeQtQavpoHoDg&ved=0CB0QFjAA&usg=AFQjCNHkRBKRpZXZX7idJ6YmSG0AIxtOdw
print_r-> http://forum.gofeminin.de/forum/dietetique/__f2955_dietetique-Diatpillen.html&sa=U&ei=C9wOUZuvCoeQtQavpoHoDg&ved=0CB0QFjAA&usg=AFQjCNHkRBKRpZXZX7idJ6YmSG0AIxtOdw

As I used all debugging methods that I know of, I don’t really know where I should start searching… any pointers ?

I made antoher testrun, and saved all data in an array, later on I wanted to stript the parameter for 1 url. Here the testcode:

    echo '<pre>';
    print_r($test).'</br>';
    echo remove_it($test[0]);
    echo '</pre>';
    break;

the output was like :

Answer 1

I made the test array and it works for me. It seems that your code is fine and something else is wrong.

Try wrapping the function input in double quotes.

remove_it("$test[0]");
