Result: Discarded

The test labeled "abs()" was the faster by 0.0248 seconds, (2.260% faster)

abs() 100%
ternary 97.74%

The abs() test took 1.0711 seconds.
The ternary test took 1.0959 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 271,871 loops for a total of 5,437,420 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (1.238) milliseconds per 271,871 loops.
  • Total difference 24.77 milliseconds for 5,437,420 loops

The iteration variablity for Code 1 was (2.2299) milliseconds and Code 2 was (2.4547) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

$GLOBALS['dummy'] = 83;
for ($j = 0; $j < 50; $j++)
	$GLOBALS['dummy2'] = abs($GLOBALS['dummy']);

$GLOBALS['dummy'] = -83;
for ($j = 0; $j < 50; $j++)
	$GLOBALS['dummy2'] = abs($GLOBALS['dummy']);

The second test, "ternary", was:

$GLOBALS['dummy'] = 83;
for ($j = 0; $j < 50; $j++)
	$GLOBALS['dummy2'] = $GLOBALS['dummy'] ? -$GLOBALS['dummy'] : $GLOBALS['dummy'];

$GLOBALS['dummy'] = -83;
for ($j = 0; $j < 50; $j++)
	$GLOBALS['dummy2'] = $GLOBALS['dummy'] ? -$GLOBALS['dummy'] : $GLOBALS['dummy'];
