Short-circuited boolean evaluationPHP ManualPrevAppendix A. Migrating from PHP/FI 2.0 to PHP 3.0NextShort-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.

side-effects.PrevHomeNextError messages have changedUpFunction true/false return values
