Detect if Variable Contains Number Sequence
<p>I have a variable like this:</p>

<p>33,100,200</p>

<p>I need to detect if it contains a specific number, say</p>

<pre><code>if(var contains '33'){
  do stuff
}
</code></pre>

<p>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.</p>

<p>Edit: This is a string not an array.</p>
