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 "(int)" was the faster by 0.0451 seconds, (4.117% faster)

(int) 100%
intval() 95.883%

The (int) test took 1.051 seconds.
The intval() test took 1.0961 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 279,946 loops for a total of 5,598,920 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (2.257) milliseconds per 279,946 loops.
  • Total difference 45.13 milliseconds for 5,598,920 loops

The iteration variablity for Code 1 was (1.4340) milliseconds and Code 2 was (2.3738) 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 ');
