The chr() test took 1.1837 seconds.
The literal test took 1.2953 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 276,669 loops for a total of 5,533,380 runs.
- Line execution difference (0.000020) milliseconds.
- Avg difference (5.578) milliseconds per 276,669 loops.
- Total difference 111.56 milliseconds for 5,533,380 loops
The iteration variablity for Code 1 was (5.9098) milliseconds and Code 2 was (7.9389) 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';
