Result: Discarded

The test labeled "concat" was the faster by 0.042 seconds, (3.505% faster)

concat 100%
ob_start() 96.495%

The concat test took 1.1555 seconds.
The ob_start() test took 1.1974 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 279,620 loops for a total of 5,592,400 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (2.099) milliseconds per 279,620 loops.
  • Total difference 41.98 milliseconds for 5,592,400 loops

The iteration variablity for Code 1 was (6.9147) milliseconds and Code 2 was (4.5670) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

ob_start();

for ($i = 0; $i < 100; $i++)
	echo 'Wheat Thins!';

$GLOBALS['dummy'] = ob_get_contents();
ob_end_clean();

The second test, "concat", was:

$value = '';
for ($i = 0; $i < 100; $i++)
	$value .= 'Wheat Thins!';

$GLOBALS['dummy'] = $value;
