Question

I have the following fairly simple code, where I need to determine if a certain value exists in an array:

$testvalue = $_GET['testvalue']; // 4
$list = '3, 4, 5';
$array = array($list);

if (in_array($testvalue, $array)) { // Code if found } else { // Code if not found }

Even though it is obvious that the number 4 is in the array, the code returns the code inside the else bracets. What have I done wrong?

Answer 1

Change the third line:

$array = array_map('trim', explode(',',$list));
