One thing about __get is that if you return an array it doesn't work directly within a
foreach...
<?php
class Foo {
function __get($prop,&$ret) {
$ret = array(1,2,3);
return true;
}
}
overload ('Foo');
//works
$foo = new Foo;
$bar = $foo->bar;
foreach($bar as $n) {
echo "$n \n";
}
//doesn't work (bad argument to foreach)
foreach($foo->bar as $n) {
echo "$n \n";
}
?>
for loops also work fine..
