Test: (bool) vs. !empty

Test: (bool) vs. !empty()

According to the documentation, empty is like isset and a reverse bool cast. Perhaps together, those are faster than the cost of the ! on empty?

Unfortunately, no history for this test is available.

The first test, "(bool)", was:

for ($j = 0; $j < 1000; $j++)
{
	$i = '1';
	$GLOBALS['dummy'] = isset($i) && (bool) $i;
}

The second test, "!empty()", was:

for ($j = 0; $j < 1000; $j++)
{
	$i = '1';
	$GLOBALS['dummy'] = !empty($i);
}
