Based on (1) saved test runs, The test labeled "chr()" was (on average) the faster by 0.0371 seconds, (5.413% faster)
The chr() test took 0.6486 seconds.
The literal test took 0.6857 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 136,655 loops for a total of 2,733,100 runs.
- Line execution difference (0.000014) milliseconds.
- Avg difference (0.000) milliseconds per 136,655 loops.
- Total difference 37.12 milliseconds for 2,733,100 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';
