Historical Results
Based on (2) saved test runs, The test labeled "echo" was (on average) the faster by 0.0396 seconds, (4.305% faster)
The echo test took 0.88 seconds.
The <?php ?> test took 0.9195 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 201,524 loops for a total of 4,030,470 runs.
- Line execution difference (0.000010) milliseconds.
- Avg difference (0.000) milliseconds per 201,524 loops.
- Total difference 39.59 milliseconds for 4,030,470 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
