Question

I have a variable like this:

33,100,200

I need to detect if it contains a specific number, say

if(var contains '33'){
  do stuff
}

But it has to not work if say they didn’t have 333 in the variable the above statement shouldn’t validate the if statement.

Edit: This is a string not an array.

Answer 1

Either explode & in_array route, or preg_match('/(?<![0-9])33(?![0-9])/',$string) route, I prefer the first.
