PHP: Select part of string (from to) and apply changes on it
<p>I want a way to change part of string according to simple marks. for example:</p>

<pre><code>$string = "I'm student (at JIC college), and I'm GENIUS.";
</code></pre>

<p>I want to select <code>at JIC college</code> or any words between brackets and change their color. (I know how to change their color). but how to select it change it then put it back. and how to do that even if I had more than 1 brackets.</p>

<pre><code>$string = "I'm student (at JIC college), and I'm GENIUS (not really).";
</code></pre>
