`if` statement that doesn't execute other functions when condition is found to be false

In PHP I can do this:

if (function1() && functio开发者_StackOverflown2()) {
     doSomething();
}

If function1() returns false, then function2() will not be executed.

I have forgotten the name of this language feature... what do you call it?

This is called short-circuit evaluation.
