Historical Results
Based on (7) saved test runs, The test labeled "echo" was (on average) the faster by 0.012 seconds, (1.426% faster)
The echo test took 0.8316 seconds.
The <?php ?> test took 0.8436 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 222,605 loops for a total of 4,452,103 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 222,605 loops.
- Total difference 12.03 milliseconds for 4,452,103 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, "echo", was:
echo $GLOBALS['x'], ' test ', $GLOBALS['y'], $GLOBALS['z'], ' test ';
The second test, "<?php ?>", was:
echo $GLOBALS['x']; ?> test <?php echo $GLOBALS['y'], $GLOBALS['z'];?> test <?php
