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'; } 

Answer 2

// Once upon a time there was a farmer  // He had multiple haystacks $haystackOne = range(1, 10); $haystackTwo = range(11, 20); $haystackThree = range(21, 30);  // In one of these haystacks he lost a needle $needle = rand(1, 30);  // He wanted to know in what haystack his needle was // And so he programmed... if (in_array($needle, $haystackOne)) {     echo "The needle is in haystack one"; } elseif (in_array($needle, $haystackTwo)) {     echo "The needle is in haystack two"; } elseif (in_array($needle, $haystackThree)) {     echo "The needle is in haystack three"; }  // The farmer now knew where to find his needle // And he lived happily ever after
