why i see some function is call by reference , what it's mean ??
for example
function &myfunction(arg1,arg2,arg3){
do soemthing.....
}
any one can help ?
The function itself is not called "by reference". The "&" is used to indicate that the function will <b>return</b> a reference.
see: http://www.php.net/manual/en/language.references.php
for more information on references and what they are good (and not good) for.
