Based on (1) saved test runs, The test labeled "chr()" was (on average) the faster by 0.1167 seconds, (7.899% faster)
The chr() test took 1.3609 seconds.
The literal test took 1.4776 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 289,063 loops for a total of 5,781,260 runs.
- Line execution difference (0.000020) milliseconds.
- Avg difference (0.000) milliseconds per 289,063 loops.
- Total difference 116.72 milliseconds for 5,781,260 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';
