Run code at the beginning of execution

[remyb]

Let's say i want to replace all appearance of word "pretty" by "beautiful", everywhere in the website.

 

An easy way to do it is to place  

ob_start('handlePage')

in the file index.php and then the function handlePage can be

public function treatPage($html) {
   return str_replace("pretty","beautiful",$html);
}

Now, I'm trying to implement this inside the module but it seems that it is not possible as I can't run my code at the beginning of the execution.

Do you know if there is a way to place my ob_start at the beginning of execution within a module ?

Like some init function ?

 

Thanks.

You would probably have to create an override of the Controller class and then add your code to the very start of execution.

init method of the Controller class should do it
