NetBeans PHP Tutorial – Linear Search #14


In this tutorial I show how to implement a linear search algorithm in PHP.


The code used for this tutorial can be seen here:

$myArray = ["orange", "lemon", "pear", "apple", "lime"];
print(linearSearch($myArray, "kiwi"));
function linearSearch($array, $toFind) {
	foreach ($array as $key=>$val) {
		if ($val == $toFind) {
			return $key;
	return -1;
