what is the goal ?
must your number be min 4 digits ?
must your number be min and max 4 digits ?
there are several options
I prefer the following
subtract 999 from your number and check the result to see if this is bigger than 0 => this way you know your number is at leaset 1000
subtract 9999 from your number and check the result to see if this is lower than 1 => this wat you know your number is max 9999
vb:
[dummy920]@@ecar0o:/home/oracle> t=8
[dummy920]@@ecar0o:/home/oracle> ((a=$t-999))
[dummy920]@@ecar0o:/home/oracle> if (( $a > 0 ))
more>then
more>echo "min 4 digits"
more>else
more>echo "too small"
more>fi
too small
[dummy920]@@ecar0o:/home/oracle> t=10000
[dummy920]@@ecar0o:/home/oracle> ((a=$t-9999))
[dummy920]@@ecar0o:/home/oracle> if (( $a < 1 ))
more>then
more>echo "max 4 digits"
more>else
more>echo "too big"
more>fi
too big

public static function test() {
$args = func_get_args();
echo static::NAME, " ".join(',', $args)."
";
}
}
class B extends A
{
const NAME = 'B';
public static function test() {
echo self::NAME, "
";
forward_static_call(array('A', 'test'), 'more', 'args');
forward_static_call( 'test', 'other', 'args');
}
}
B::test('foo');
