POGiving PHP include()'d files parent variable scope

Body
copied!<p>Is there anyway to for an included file to be used in a parent scope to the one it was called in? The following example is simplified, but does the same job.</p> <p>In essence, a file will be included by a function, but would like the scope of the included file to be the scope of where the function that included it was called from.</p> <p>main.php:</p> <pre><code><?php if(!function_exists('myPlugin')) { function myPlugin($file) { if(file_exists($file) { require $file; return true; } return false; } } $myVar = 'something bar foo'; $success = myPlugin('included.php'); if($success) { echo $myResult; } </code></pre> <p>included.php:</p> <pre><code><?php $myResult = strlen($myVar); </code></pre> <p>Thanks in advance,<br> Alexander.</p> <h2>EDIT: Solution</h2> <p>Well, sort of, thanks to the contributions by Chacha102.<br> Can be called from within a class now too!</p> <p>main.php</p> <pre><code><?php class front_controller extends controller { public function index_page() { $myVar = 'hello!'; // This is the bit that makes it work. // I know, wrapping it in an extract() is ugly, // and the amount of parameters that you can't change... extract(load_file('included.php', get_defined_vars(), $this)); var_dump($myResult); } public function get_something() { return 'foo bar'; } } function load_file($_file, $vars = array(), &$c = null) { if(!file_exists($_file)) { return false; } if(is_array($vars)) { unset($vars['c'], $vars['_file']); extract($vars); } require $_file; return get_defined_vars(); } </code></pre> <p>included.php:</p> <pre><code><?php $myResult = array( $myVar, $c->get_something() ); </code></pre> <p>If you want to reference a method it has to be public, but the result is as expected:</p> <pre><code>array(2) { [0]=> string(6) "hello!" [1]=> string(7) "foo bar" } </code></pre> <p>Now, this doesn't really have any practical use, and the only reason I wanted to know how to do this is because I am stubborn. The thought came into my head, and would not let it defeat me :D</p> <p><code><rant></code><br> Thanks to all who contributed. Except the person who boo'd me. It was a simple enough question, and have now figured out that (complicated) solution exists.<br> Screw whether it "conforms to the PHP way of doing things". Ever told a client "Oh no, we shouldn't do that, it's not the correct way to do things!"? Thought not.<br> <code></rant></code></p> <p>Thanks again to Chacha102 :)</p>
