What is the difference between these two pieces of code?
class something {
static function doit() {
echo 'hello world';
}
}
something::doit();
and the same but without the static keyword
class something {
function doit() {
echo 'hello world';
}
}
something::doit();
They both work the same is it better to use the static keywords? Am i right in understanding that it doesn’t instantiate the class if you use the static method?
The second example is technically incorrect – if you turn on E_STRICT error reporting you’ll see that PHP is actually throwing an error.
In other words, it’s being nice and letting you call the function anyway.
