Will someone explain this code snippet to me in word?

 

    foreach ($this->viewData as $key => $value) {
        $$key = $value;
    }

[Orio]

First, I must say this is some ugly piece of code.

This goes over all of the elements in $this->viewData. Then it creates a variable for every value, and the name of the value (the variable name) is the key's value.

 

 

Example

If viewData contains

[keyname] => "value",
[something] => "random_val"

 

Running these two lines will create two variables: $keyname, $something (The first with the value "value" and the second holding "random_val").

 

 

Orio.
