Question

I have a string and it can contain values like this
$string = ‘1,2,3,4,5’;
I wanna put a check that will see if the string contains 4 or 5
if it contains 4 or 5 then I want to echo success
otherwise if it contains 9 or 10 I wanna echo fail

I know there is a n in_array function but not sure how to use it
thanks

You can test for the number 4 like this:

if(in_array('4', explode(',', $string))) echo "it's in there";

or just by string searching:

if(strpos(',4,', ','.$string.',') !== false) echo "it's in there";
