Having an assignment to “this” can be unproductive
“This report lists all the Classes containing assignements to ‘$this’.
It provides the following information:
Class full name.”
Remedy –
Modify the source code and do not assign to ‘$this’.
” <?php
class foo {
function foo(){
// construct
}
function bar(){
$this = true;
}
}
?>
“
Why you should care
In PHP the assignment to $this is used to unset the object, or it is a typographical error. Unsetting an object is not really necessary for performance reasons. Removing all variables that point to the object to be unset will have the same result. It is also important to remember to do so because the result will be a fatal error. As such, in PHP5 mode, this kind of practice could provoke a failure.
