## Details
## Performance

See [8fold XML Builder](https://github.com/8fold/php-xml-builder#readme) for
details.
The `/comparisons` folder can be used to run performance tests locally to compare the same output using:

1. straight HTML,
2. standard PHP,
3. PHP HTML Builder alongside standard PHP (the Element class),
4. PHP HTML Builder only (the Document class), and
5. PHP HTML Builder only using PSR-4 autoloading.

These results are from February 26th, 2024:

## Usage (advanced)
|Configuration |Average time in milliseconds |Median time in milliseconds |
|:---|---:|---:|
|1 |0.0399683 |0.0017415 |
|2 |0.0953241 |0.0160480 |
|3 |1.6026525 |1.4603320 |
|4 |1.7849769 |1.7918970 |
|5 |8.9957415 |8.8755520 |

TODO
Things worth noting (as rough interpretations):

HTML Builder has the ability to help create valid HTML documents based on the
HTML specification.
1. PHP being used as a template engine has a negligible impact on speed.
2. Using `require_once` without PSR-4 autoloading decreases speed by roughly 1 millisecond; however, once the code is made available, very little additional cost seems to be present.
3. Using PSR-4 decreases speed by roughly 6 milliseconds; however, ensures everything is present and available.
