Simple way to count the vowels in a string in PHP?
<p>If I define a simple string variable, how would I count and output the number of vowels in the string in the simplest possible way?</p>

<p>I have searched and found a number of similar ways to do so, but most seem more complex than necessary.  They are all functional and maybe the complexity IS necessary, but I am looking for the simplest solution possible.</p>

<p>My string variable would be something like:</p>

<pre><code>$someString = "This is some text with some more text and even more text."
</code></pre>

<p>I just want to display the total instances of a,e,i,o,u.  Thank you in advance.</p>
