Based on (4) saved test runs, The test labeled "echo" was (on average) the faster by 0.0371 seconds, (3.849% faster)
The echo test took 0.9271 seconds.
The <?php ?> test took 0.9642 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 210,337 loops for a total of 4,206,745 runs.
- Line execution difference (0.000009) milliseconds.
- Avg difference (0.000) milliseconds per 210,337 loops.
- Total difference 37.11 milliseconds for 4,206,745 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
