Change variable value in CodeIgniter subview - php

Question

I have a main view in my CI app in which I declare a variable.
That main view loads several subview in a loop.
I would like these subviews to modify my variable so that at the end of the loop its value would be updated.
Example:
main_view.php
<?php
$my_var = false;
foreach($a_views as $s_view){
$this->load->view($s_view, array('my_var' => $my_var);
}
var_dump($my_var); // Still false
?>
sub_view.php
<?php $my_var = true; ?>

Check out the code for the $this->load->view function.
The data you pass to the view is "one-way" which means it's available and can be modified only in the view itself.
Which means you'll have to find another way to achieve what you're trying to achieve.
Keep in mind that according to what I've understood from your question you're trying to have some "logical manipulation" using "views" which is kind of breaking the MVC architecture.
/**
* View Loader
*
* Loads "view" files.
*
* #param string $view View name
* #param array $vars An associative array of data
* to be extracted for use in the view
* #param bool $return Whether to return the view output
* or leave it to the Output class
* #return object|string
*/
public function view($view, $vars = array(), $return = FALSE)
{
return $this->_ci_load(array('_ci_view' => $view, '_ci_vars' => $this->_ci_prepare_view_vars($vars), '_ci_return' => $return));
}
