The chr() test took 0.5446 seconds.
The literal test took 0.5627 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 128,659 loops for a total of 2,573,180 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (0.908) milliseconds per 128,659 loops.
- Total difference 18.16 milliseconds for 2,573,180 loops
The iteration variablity for Code 1 was (1.6124) milliseconds and Code 2 was (1.8874) 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';
