Question

Which function was introduced to help automate the inclusion of class files?

(a) __load()

(b) __preload()

(c) __autoload()

(d) __inload()

I had been asked this question in an interview for internship.

Query is from Object Tools in chapter Object Tools and Design and Variables in PHP of PHP

Answer 1

Correct choice is (c) __autoload()

Best explanation: When the PHP engine encounters an attempt to instantiate an unknown class, it invokes the __autoload() function, passing it the class name as a string. It is up to the implementer to define a strategy for locating and including the missing class file.
