Indeed it is very easy to learn, but sometimes it is not very easy to
debug,
because there is no indication for missing declarations (or spelling
errors).
And the actual style has exceptions: var is used to declare variables
for classes,
but I cannot use it to declare var's for functions (or ensure I use only
declared var's).
There is also a difference between accessing a variable, static or
constant.
<?PHP
class foo {
var $bar_v = "variable";
const bar_c = "constant";
static $bar_s = "static";
}
$fooo = new foo();
$bar_v = "bar_v";
print $fooo->bar_v; // these 2 work different
print $fooo->$bar_v;
print foo::bar_c; // then these 2
print foo::$bar_s;
?>
