The test labeled "ternary" was the faster by 0.0428 seconds, (4.067% faster)

ternary 100%
abs() 95.933%

The ternary test took 1.01 seconds.
The abs() test took 1.0529 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 257,912 loops for a total of 5,158,240 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (2.141) milliseconds per 257,912 loops.
  • Total difference 42.82 milliseconds for 5,158,240 loops

The iteration variablity for Code 1 was (3.1663) milliseconds and Code 2 was (3.0743) 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'];
