FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package html-min
html-min
A fast HTML5 compressor and minifier for PHP. Strips redundant whitespace, comments, optional tags, and default attributes, then sorts what's left so your gzip layer has less work to do.
Built on native \DOMDocument — no third-party DOM dependencies.
Requirements
- PHP 8.3, 8.4, or 8.5
- ext-dom, ext-libxml, ext-mbstring
Installation
Usage
Wrap any block in <nocompress>…</nocompress> to keep its whitespace intact.
Configuration
Every option is a chainable setter. All defaults are shown — the example below reproduces the default configuration.
Each setter returns $this, so you can configure and call minify() in one chain.
Inline CSS and JS minification
By default the contents of <style> and <script> blocks round-trip untouched.
Enable the two opt-in toggles to minify them:
The bundled minifiers are zero-dependency and conservative:
- CSS — strips
/* … */comments and collapses whitespace; the contents of strings andurl(…)are preserved. - JS — removes comments and collapses horizontal whitespace while preserving newlines (so Automatic Semicolon Insertion is unaffected), strings, regex literals, and template literals. Identifiers are never renamed.
Scripts that are not JavaScript are left alone automatically: a <script>
whose type is, for example, application/ld+json or text/x-template, and any
<script src="…">, passes through unminified.
Using a different minifier
For aggressive minification (identifier renaming, dead-code removal), plug in a
third-party tool with setInlineCssMinifier() / setInlineJsMinifier(). Each
takes any callable(string): string; pass null to restore the bundled default.
If a bundled minifier throws, the original source is kept and a warning is sent
to the PSR-3 logger (when one is set via setLogger()), so a minifier bug can
never corrupt the page. User-supplied callables let their exceptions propagate.
Extending
To run your own pass over every element during minification, implement
Akankov\HtmlMin\Contract\DomObserver and register it:
Benchmarks
Measured against voku/html-min, wyrihaximus/html-compress, zaininnari/html-minifier, and abordage/html-min on a corpus of real-world HTML pages.
| adapter | median ms/op | geomean ms/op | parse failures | avg gzipped ratio |
|---|---|---|---|---|
| akankov/html-min | 1.9 | 1.9 | 0 / 15 | 90.7% |
| akankov/html-min (inline) | 2.1 | 2.5 | 0 / 15 | 87.6% |
| voku/html-min | 3.3 | 3.6 | 0 / 15 | 90.7% |
| wyrihaximus/html-compress | 6.0 | 7.5 | 0 / 15 | 87.0% |
| zaininnari/html-minifier | 9.5 | 8.3 | 0 / 15 | 94.8% |
| abordage/html-min † | 0.2 | 0.2 | 0 / 15 | 90.2% |
The table above is regenerated by make bench from the latest run.
See latest.md for the per-fixture detail (speed, peak memory,
gzipped compression ratio, methodology, and non-claims). Reproduce with
make bench-install && make bench (requires Docker).
Development
CI runs the full matrix (PHP 8.3 / 8.4 / 8.5) on every push and pull request.
