I am learning perl and my book describes "boolean short circuiting". Basically: function1() OR function2(); (function2 never is evaluated if function1 is true). Will this work in PHP for any function?Yes. From my experience, it will work that way. I don't know if it's that way for every version or not, though. Same thing for AND, too... function1() AND function2() If function1() comes out FALSE, then function2() isn't evaluated. -- ---John Holmes...
