Historical Results
Based on (1) saved test runs, The test labeled "echo" was (on average) the faster by 0.0096 seconds, (1.917% faster)
The echo test took 0.4927 seconds.
The <?php ?> test took 0.5023 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 137,925 loops for a total of 2,758,500 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 137,925 loops.
- Total difference 9.63 milliseconds for 2,758,500 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:
for ($j = 0; $j < 100; $j++) echo 'some text';
The second test, "<?php ?>", was:
for ($j = 0; $j < 100; $j++)
{
?>some text<?php
