this question has answer here: alternative (k&r) c syntax function declaration versus prototypes 6 answers i've seen few function definitions while playing gnu bison: static value ripper_pos(self) value self; { //code here } why type of self outside of parenthesis? valid c? those old k&r style function parameter declarations, declaring types of parameters separately: int func(a, b, c) int a; int b; int c; { return + b + c; } this same more modern way declare function parameters: int func(int a, int b, int c) { return + b + c; } the "new style" declarations universally preferred.

i don't understand behavior in php (since 5.4 ? ) class test { function __construct() { return null ; } } ; $a = new test() ; if($a) { echo "i printing this. why printing ??" ; } $a should equal null passes test if()... in case (if arguments invalid exemple) possible null object when using 'new' ? constructors not return anything. after ctor has run, object has been created. return null ignored. edit: if possible return null in ctor when failed bad practice. throw exception clear message instead. help page: http://www.php.net/manual/en/language.exceptions.php
