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 0.015 seconds, (1.592% faster)

intval() 100%
(int) 98.408%

The intval() test took 0.9257 seconds.
The (int) test took 0.9406 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 237,772 loops for a total of 4,755,440 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.749) milliseconds per 237,772 loops.
  • Total difference 14.97 milliseconds for 4,755,440 loops

The iteration variablity for Code 1 was (6.5347) milliseconds and Code 2 was (4.6964) 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 ');
