I have checked the PHP source code and can not find the "require" function.
I only found a piece code relatives to it on main/main.c from line 976

switch (EG(current_execute_data)->opline->extended_value) {

    case ZEND_EVAL:

        function = "eval";

        is_function = 1;

        break;

    case ZEND_INCLUDE:

        function = "include";

        is_function = 1;

        break;

    case ZEND_INCLUDE_ONCE:

        function = "include_once";

        is_function = 1;

        break;

    case ZEND_REQUIRE:

        function = "require";

        is_function = 1;

        break;

    case ZEND_REQUIRE_ONCE:

        function = "require_once";

        is_function = 1;

        break;

    default:

        function = "Unknown";

}

Do you know which file defines the "function"?

My Answer:
You can find the function in the code or documentation of the software or programming language you are using. If you are looking for a specific function in a programming language, you can search for it in the official documentation or online resources such as tutorials, forums, and community websites. If you are working with a specific software application, you can check the user manual or help documentation provided by the software developer.
