How to display an Array under alphabetical letters using PHP?
<p>I have an array that already contains all it's values in alphabetical order:</p>

<pre><code>Alligator
Alpha
Bear
Bees
Banana
Cat
Cougar
</code></pre>

<p>Now I just want to list the first letter each starts with above it like so:</p>

<pre><code>A
---

Alligator
Alpha

B
---

Bear
Bees
Banana

C
---

Cat
Cougar

etc...
</code></pre>

<p>How can this be done?</p>
