Test: array_keys(array_flip()) vs. array_unique()

Do note that this test is only using integer values (which is common for this), long strings will take longer to hash as array keys.

Unfortunately, no history for this test is available.

The first test, "array_keys(array_flip())", was:

$array = array();
for ($n = 0; $n < 8; $n++)
{
	for ($i = 0; $i < 50; $i++)
		$array[] = $i;
}

$array = array_keys(array_flip($array));

The second test, "array_unique()", was:

$array = array();
for ($n = 0; $n < 8; $n++)
{
	for ($i = 0; $i < 50; $i++)
		$array[] = $i;
}

$array = array_unique($array);
