I want to do something like this

if($abc="asdf","sdfg","dfgh") {
echo "Something";
}

What should I do? Do I have to use seperate rules with || ?

Answer 1

You would use in_array() for such purposes:

if (in_array($abc, array('asdf', 'sdfdg', 'qweqe'))) {
    // something
}

The third parameter of in_array() can be used to perform strict type checks between the needle and each item of the haystack, similar to ===.
