Some basic regulation for the beginner php developer

You will probably want to use this set of basic commands

• require
• require_once
• include
• include_once

Take in mind the difference between them.
The difference between require and require_once is: ???
The difference between include and include_once is: ???
Use only xxx to call libraries and use only xxx to include snippets of code written to different files.
Remember:

• redirect move the execution of the code to the target file and you are allowed to call the target file passing it some parameters.
  

for instance: redirect("./come_modello/edit.php?id=$cm->id");

• include requires the name of the called file "clean", without "?id=$cm->id", for instance, and the target file is executed as it were written in the place of the calling row.
  

You need these two informations to correctly include library files into target files called through redirect or include.
