Test: chr v. literal
How much worse is chr() than just a literal (if it's cleanly representable.)
Run this test again Return to test menuResult: Discarded
The test labeled "chr()" was the faster by 0.0614 seconds, (7.017% faster)
The chr() test took 0.8139 seconds.
The literal test took 0.8754 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 211,140 loops for a total of 4,222,800 runs.
- Line execution difference (0.000015) milliseconds.
- Avg difference (3.071) milliseconds per 211,140 loops.
- Total difference 61.42 milliseconds for 4,222,800 loops
The iteration variablity for Code 1 was (3.0108) milliseconds and Code 2 was (5.0950) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "chr()", was:
$GLOBALS['dummy'] = chr(65);
The second test, "literal", was:
$GLOBALS['dummy'] = 'A';
