PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: is_float vs. Float Casting

Cast vs is_float

Run this test again Return to test menu

Result: Discarded

The test labeled "is_float" was the faster by 0.0198 seconds, (1.780% faster)

is_float 100%
Casting 98.22%

The is_float test took 1.0906 seconds.
The Casting test took 1.1104 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 256,807 loops for a total of 5,136,140 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.988) milliseconds per 256,807 loops.
  • Total difference 19.76 milliseconds for 5,136,140 loops

The iteration variablity for Code 1 was (2.4322) milliseconds and Code 2 was (3.3558) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "is_float", was:

$a = is_float($GLOBALS['test']);

The second test, "Casting", was:

$a = (float) $GLOBALS['test'] === $GLOBALS['test'];
