PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: (int) vs. intval

the semantic difference here is only that intval() can convert bases, whereas (int) cannot.

Result: Discarded

The test labeled "intval()" was the faster by 0.0214 seconds, (3.085% faster)

intval() 100%
(int) 96.915%

The intval() test took 0.6719 seconds.
The (int) test took 0.6933 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 132,626 loops for a total of 2,652,520 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (1.069) milliseconds per 132,626 loops.
  • Total difference 21.39 milliseconds for 2,652,520 loops

The iteration variablity for Code 1 was (6.9816) milliseconds and Code 2 was (6.7516) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

for ($j = 0; $j < 100; $j++)
	$i = (int) '42 ';

The second test, "intval()", was:

for ($j = 0; $j < 100; $j++)
	$i = intval('42 ');
