PHP $_GET is set to a specific string

Question

I am looking to expand upon my PHP Knowledge, and have done some research on the internet. What I am trying to do is execute some code when a variable is set in the URL.

    if($_GET['variable']) && $_GET['variable'] = "something") {
        echo "Do This.";
    }

However, the code will still run regardless what variable is equal to, as long as it is set. How would I go about achieving mygoal?

1) You should get a few errors for this code 2) maybe try `isset()` 3) Learn the difference between all three equal signs — Rizier123, Aug 02 '15 at 21:29
because it's always true `=` which is an assigment; compare `==` against something. — Funk Forty Niner, Aug 02 '15 at 21:30
@Fred-ii- The assignment is outside of the if statement: `if($_GET['variable'])` :) — Rizier123, Aug 02 '15 at 21:30
@Rizier123 then the question's a dupe mix of http://stackoverflow.com/questions/2063480/the-3-different-equals and http://stackoverflow.com/questions/4261133/php-notice-undefined-variable-and-notice-undefined-index - new canonical required? ;-) — Funk Forty Niner, Aug 02 '15 at 21:34
*assigment* - groan, I forgot the "n" --- "assignment". There. — Funk Forty Niner, Aug 02 '15 at 21:38

This should works :

if(isset($_GET['variable']) && $_GET['variable'] == "something") {
    echo "Do This.";
}

some added tid bits of information as to why it should work and why the OP's code failed in the first place, would be lovely. Enlighten everyone, and for future visitors. – Funk Forty Niner Aug 02 '15 at 21:40
