Historical ResultsBased on (2) saved test runs, The test labeled "(string)" was (on average) the faster by 0.027 seconds, (3.182% faster)
The (string) test took 0.8213 seconds.
The no cast test took 0.8483 seconds.
Each test case ran 20 random code order iterations consisting of 217,584 loops for a total of 4,351,680 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (0.000) milliseconds per 217,584 loops.
- Total difference 26.99 milliseconds for 4,351,680 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.
The first test, "(string)", was:
for ($j = 0; $j < 1000; $j++) $GLOBALS['dummy'] = 'good morning! ' . (string) $j . ' good night!';
The second test, "no cast", was:
for ($j = 0; $j < 1000; $j++) $GLOBALS['dummy'] = 'good morning! ' . $j . ' good night!';
