The question is in the title.

A:
They are non-static by default:
public function method() {
}
You will get an E_STRICT if you call it statically, but I don't think you can easily enforce that it can only be called on an instance - if you try to check You could do $this I think you will get an error.isset($this) as Artefacto says and throw an exception if it isn't set.

You can throw an exception if `isset($this)` is `false`.

This can still be called as a static function.

@Artefacto Have you seen any code doing this explicitly in all non-static methods? That looks cumbersome. Hopefully you will get some sort of error inside the method if $this is not set.

@Artefacto: thanks, tested and updated it. for some reason i thought that would fail.

@Alex Yes, you get a fatal error if you use `$this` in a static context, which most non-static functions will do (if they don't access the instance, I suppose they could be static instead).

A:
<?php
class abc() {
public function foo() {
if (!isset($this)) {
throw new Exception('Method is non-static.');
exit();
}
}
}
$c = new abc();
$c->foo();
?>
Not tested.
