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 0.0089 seconds, (0.723% faster)

intval() 100%
(int) 99.277%

The intval() test took 1.2189 seconds.
The (int) test took 1.2278 seconds.


Each test case ran 20 random code order iterations consisting of 264,583 loops for a total of 5,291,660 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.444) milliseconds per 264,583 loops.
  • Total difference 8.88 milliseconds for 5,291,660 loops

The iteration variablity for Code 1 was (4.3935) milliseconds and Code 2 was (3.8954) milliseconds. The lower and the closer together there values are the more accurate the results are.


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 ');
