Short-circuited boolean evaluation Пред.
Приложение D. Migrating from PHP/FI 2 to PHP3
- In PHP3.0 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.
