include() vs. include_once()

[davidklonski]

Hi

Could someone explain me the difference between 'include()' and 'include_once()'?

Why would someone choose to use 'include()' over 'include_once()'?

thanks in advance

The include_once() statement includes and evaluates the specified file during the execution of the script. This is a behavior similar to the include() statement, with the only difference being that if the code from a file has already been included, it will not be included again. As the name suggests, it will be included just once.
