Opening php file declaration question
<p>I've inherited an existing php web site.  The file names end with the php extension and the code appears to be php.</p>

<p>Just wondering why the opening file declaration is "<code>&lt;?</code>" instead of "<code>&lt;?php"</code>.</p>

<p>What is the difference between the 2 and why would one be used over the other.</p>

<p>Thanks!</p>
