Question

How can I use two or more strings?

This is what I’m using to do just one string.

if ($input == "test")
{
    echo "$imput is equal to test.";
}

If I understand you correctly, something like this might work best if you have many strings to compare with.

$string = array("foo", "bar", "hello", "world");
foreach ($string as $s) {
    if ($input == $s) {
        echo "$input is equal to $s";
        break;
    }
}
