Can't be that difficult, I'm just a lost newbie!

How can I pass execution from one php script to another?

 

From HTML form you can specify action attribute to point to a separate PHP file.

However, I'm not sure what you mean by passing an execution to another script.

You can use require/require_once or include/include_once to execute a PHP code located in a separate file.

 

or load the file and execute it with eval
