How can I check if an array contains a specific value in php?

Question

I have a PHP variable of type Array and I would like find out if it contains a specific value and let the user know that it is there. This is my array:

Array ( [0] => kitchen [1] => bedroom [2] => living_room [3] => dining_room) 

and I would like do something like:

if(Array contains 'kitchen') {echo 'this array contains kitchen';}

What is the best way to do the above?

Answer 1

Use the in_array() function.

$array = array('kitchen', 'bedroom', 'living_room', 'dining_room');

if (in_array('kitchen', $array)) {
    echo 'this array contains kitchen';
}
