in_array

The in_array() function in PHP checks if a value exists in an array - returning true if it does, or false otherwise.

The last argument in this function forces a strict type check of the value in PHP. Since Ruby does not consider a Fixnum of 1 and a String of ‘1′ to be the same - it always operates as if the last argument were set to true.

PHP

$my_array = array('a', 'b', 'c', 'd');
if('a', in_array($a), true) {
	echo 'Found it in the array';
}
// => Found it in the array

Ruby

my_array = [ "a", "b", "c", "d" ];
if( my_array.include?('a') ) {
	 puts 'Found it in the array';
}
# => Found it in the array
