I see this all over the place, but I don't think it stores the variable

$foo:
class Foo {
private $foo;

I am always using 'foo' in conversation and finally said it enough that
the CEO used it in a meeting the other day. Setter functions are cool.
hmmm, who wants to write setters for 100's of properties? ...
see below for an alternative ...
Nevermind, it does need private $foo; it works without it, but not if
you want to use a default from within the class.
if you set private $foo = 'foo';
print $f->__getFoo();
$f->__setFoo('bar');
print $f->__getFoo();
<?php
class Foo
{
private $foo = 'foo';
function __get($k)
{
if (isset($this->{$k})) {
return $this->{$k};
}
throw new Exception("non existing property!");
}
function __set($k, $v)
{
if (isset($this->{$k})) {
$this->{$k} = $v;
return;
}
throw new Exception("non existing property!");
}
}
$f = new Foo;
echo $f->foo,"\n";
$f->foo = "bar";
echo $f->foo,"\n";
Yields:
foo
bar
