The test labeled "(string)" was the faster by 0.0578 seconds, (5.221% faster)
The (string) test took 1.0495 seconds.
The "$string" test took 1.1073 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 271,651 loops for a total of 5,433,020 runs.
- Line execution difference (0.000011) milliseconds.
- Avg difference (2.890) milliseconds per 271,651 loops.
- Total difference 57.81 milliseconds for 5,433,020 loops
The iteration variablity for Code 1 was (3.6042) milliseconds and Code 2 was (6.6145) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "(string)", was:
for ($j = 0; $j < 1000; $j++) $GLOBALS['dummy'] = (string) $j;
The second test, ""$string"", was:
for ($j = 0; $j < 1000; $j++) $GLOBALS['dummy'] = "$j";
