in other (compiled) programming languages, a function prototype specifies the "contract" between the function and its callers, and makes explicit the programmer's intentions as to how the function is to be called. Usually expected parameter types and passing methods specified by the function as checked at compile-time to ensure that parameters passed to the function are as expected. in specifying a parameter as by-reference, the programmer makes it clear that the function may modify the value of the parameter. In specifying the parameter as by-value, s/he states that the passed in parameter will not reflect any changes when the function returns. This is its "contract" with the caller of the function. However, allowing call_time_pass_reference violates this by bypassing the programmer's explicit intention in not declaring a parameter by reference. l0t3k -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
