I use classes a lot and don't have this problem. This is because
the names of the class ( and thus the constructor name ) tends to be a noun
and otherfunctions tend to be verbs, so I am don't have this kind of clash.
I am VERY glad that PHP has classes and I use them alot.
However ....
<rant_mode>
My biggest bug-bear with classes in PHP is the lack of a "super" operator
There are times when I would really like to be able to do:
class A
{
function DoStuff()
{
.....
}
}
class B extends A
{
function DoStuff()
{
.....
$super->DoStuff(); // Calls the function in A
}
}
A "super" operator could allow a fixed name constructor ( like the
"__new__" in Python )
and the parent constructor could be called using "super", which would
eliminate
Matthew's problem.
