Historical Results

Based on (1) saved test runs, The test labeled "abs()" was (on average) the faster by 0.0229 seconds, (2.333% faster)

abs() 100%
ternary 97.667%

The abs() test took 0.9574 seconds.
The ternary test took 0.9803 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 224,324 loops for a total of 4,486,480 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.000) milliseconds per 224,324 loops.
  • Total difference 22.87 milliseconds for 4,486,480 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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'];
