Test: chr v. literal
How much worse is chr() than just a literal (if it's cleanly representable.)
Run this test again Return to test menuResult: Discarded
The test labeled "chr()" was the faster by 0.0172 seconds, (1.556% faster)
The chr() test took 1.09 seconds.
The literal test took 1.1072 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 279,900 loops for a total of 5,598,000 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.862) milliseconds per 279,900 loops.
- Total difference 17.23 milliseconds for 5,598,000 loops
The iteration variablity for Code 1 was (3.6270) milliseconds and Code 2 was (3.7982) 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';
