How to check if an array value exists

Question

How can I check if $something['say'] has the value of 'bla' or 'omg'?

$something = array('say' => 'bla', 'say' => 'omg');

Answer 1

Using the instruction if?

if(isset($something['say']) && $something['say'] === 'bla') {
    // do something
}

By the way, if you are assigning the same value to the key, let's say twice, your array will end up having just one value. I hope this helps you.
