Issue with deprecated php function
<p>I have this warning here: <code>Function split() is deprecated</code>
I tried replacing it with the explode function. I don't know, maybe I did something wrong, but this is the part of the code apparently deprecated, could you please help me with this?</p>

<p>thanks!</p>

<pre><code>$kt = split(' ', $levels);
</code></pre>
