# Short-circuited boolean evaluation

In PHP 3.0 boolean evaluation is short-circuited. This means that in an expression like `(1 || test_me())`, the function test_me() would not be executed since nothing can change the result of the expression after the `1`.

This is a minor compatibility issue, but may cause unexpected side-effects.
