Based on (4) saved test runs, The test labeled "chr()" was (on average) the faster by 0.0322 seconds, (4.311% faster)
The chr() test took 0.7148 seconds.
The literal test took 0.747 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 170,362 loops for a total of 3,407,230 runs.
- Line execution difference (0.000009) milliseconds.
- Avg difference (0.000) milliseconds per 170,362 loops.
- Total difference 32.20 milliseconds for 3,407,230 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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';
