"require_once" and "if" are both statements, so why does the PEAR standard say that you need parenthesis for "if" and not for "require_once"?
cause 'if' requires parenthesis for correct syntax and if i would agree you than we had to rite require_once ('file.php'); and not require_once('file.php'); same for return return ($var); !!! BUT: Note: Note that since return() is a language construct and not a function, the parentheses surrounding its arguments are only required if the argument contains an expression. It is common to leave them out while returning a variable, and you actually should as PHP has less work to do in this case. Note: You should never use parentheses around your return variable when returning by reference, as this will not work. You can only return variables by reference, not the result of a statement. If you use return ($a); then you're not returning a variable, but the result of the expression ($a) (which is, of course, the value of $a). i don't know if "It is common to leave them out while returning a variable, and you actually should as PHP has less work to do in this case." also applies to 'require' so i think you should never write parenthesis where it is not required. -- Sebastian
