Cool ...
Now that we're talking about PHP ....
I'd like to ask a question ....
You know the "overloading" function in C++ .... Is that possible in PHP ?
Basically , I'd like to define more than one function having the same name
but different number of variables/parameters ... so PHP would know which one
I'm calling depending on the numbwer/type of the variables ...
exemple :
<?
function arcad_func( $var_a )
{
echo $vara ;
}
;
function arcad_func( $var_a , $var_b )
{
echo $vara . $var_b ;
}
?>
<?
arcad_func("Hello!");
arcad_func("Hello" , "World!")
?>
Would this work ?
Thanks...
