Detect if Variable Contains Number Sequence

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.

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

The Preg Match Worked the best.

I dont quite understand the second part of your question, but this may be the code you're looking for:

if(strpos($var, '33') !== false) {
    // do stuff
}

Edit Oh, now I think i get what you're looking for

if(in_array('33', explode(',', $var)) {
    // do stuff
}

It's not an array, will that make a difference?
