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.

The test labeled "(int)" was the faster by 0.0168 seconds, (1.602% faster)

(int) 100%
intval() 98.398%

The (int) test took 1.0341 seconds.
The intval() test took 1.0509 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 283,255 loops for a total of 5,665,100 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.842) milliseconds per 283,255 loops.
  • Total difference 16.84 milliseconds for 5,665,100 loops

The iteration variablity for Code 1 was (1.9658) milliseconds and Code 2 was (1.9828) 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 ');
