PHP read everything until first comma
<p>I have string that will look like this:  </p>

<pre><code>$string = "hello, my, name, is, az";  
</code></pre>

<p>Now I just wanna echo whatever is there before first comma. I have been using following:  </p>

<pre><code>echo strstr($this-&gt;tags, ',', true);
</code></pre>

<p>and It has been working great, but the problem it only works php 5.3.0 and above. I am currently on PHP 5.2.</p>

<p>I know this could be achieve through regular express by pregmatch but I suck at RE.</p>

<p>Can someone help me with this.</p>

<p>Regards,</p>
