Question

I am trying to return a variable from a function and print it out. Its displaying unexpected T_STRING right now…. Can someone help?

function reg_word($i){
        $reg_word = "/[^A-Za-z0-9 ]/";
        $i = preg_replace($reg_word, '', $i);
    }

$suggestion = function reg_word($_POST['suggestions']);

    print_r($suggestion);

Answer 1

function reg_word($i){
    $reg_word = "/[^A-Za-z0-9 ]/";
    return preg_replace($reg_word, '', $i);
}

$suggestion = reg_word($_POST['suggestions']);

print_r($suggestion);

You had function keyword before reg_word($_POST['suggestions']); – you don’t need it.
You need to use return keyword to return something from a function.
