<h3> this is in the body of the main file</h3>

<blockquote>
<h4>From the manual re. include() :</h4>
<p>"When a file is included, the code it contains inherits

<br/>the variable scope of the line on which the include occurs.

<br/><br/>Any <b>variables</b> available at that line in the calling file will be available <br/>
within the called file, from that point forward.

<br/><br/>However, all <b>functions and classes</b> defined in the included file have the global scope."*** <br><br>[*** but only after the line on which they're included]</p>

<p>Try moving the php inculde around to see how it affects the scope of $a and hello()</p>
