The chr() test took 2.1321 seconds.
The literal test took 2.2876 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 284,407 loops for a total of 5,688,140 runs.
- Line execution difference (0.000027) milliseconds.
- Avg difference (7.773) milliseconds per 284,407 loops.
- Total difference 155.46 milliseconds for 5,688,140 loops
The iteration variablity for Code 1 was (37.6403) milliseconds and Code 2 was (46.5347) 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';
