Imagine that you have this PHP code:$array1 = array("henk", "jackson", "henk");. Is there a way to check if $array1 has two of the same values in it (in this case henk) and then make it delete one of them so one stays in the array?

All you need is array_unique():

$array1 = array("henk", "jackson", "henk");
$array2 = array_unique($array1);
print_r($array2);

Result:

Array
(
    [0] => henk
    [1] => jackson
)
