Historical Results

Based on (7) saved test runs, The test labeled "abs()" was (on average) the faster by 0.0128 seconds, (1.621% faster)

abs() 100%
ternary 98.379%

The abs() test took 0.7769 seconds.
The ternary test took 0.7897 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 178,009 loops for a total of 3,560,171 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.000) milliseconds per 178,009 loops.
  • Total difference 12.80 milliseconds for 3,560,171 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'];
