How Can I Optimize My PHP HTML Output for Smaller Page Sizes?

Optimizing HTML Output for Smaller Page Size

Minimizing HTML output can significantly reduce page size, improving page load times and user experience. Here are techniques to minify PHP page HTML output:

CSS and JavaScript

Use tools like Minify (https://github.com/mrclay/minify) to reduce the size of external CSS and JavaScript files.

HTML

Enable GZIP Compression

Tell Apache to compress HTML responses with GZip, leading to a 70% size reduction. Configure as per your Apache version:

  • Apache 1.3: Use mod_gzip
  • Apache 2.x: Use mod_deflate

Remove White Spaces

Incorporate the following PHP snippet to remove unnecessary white spaces from HTML using ob_start's buffer:

function sanitize_output($buffer) {
    $search = array(
        '/\>[^\S ]+/s',     // strip whitespaces after tags, except space
        '/[^\S ]+\</s',     // strip whitespaces before tags, except space
        '/(\s)+/s',         // shorten multiple whitespace sequences
        '/<!--(.|\s)*?-->/' // Remove HTML comments
    );

    $replace = array(
        '>',
        '<',
        '\1',
        ''
    );

    $buffer = preg_replace($search, $replace, $buffer);

    return $buffer;
}

ob_start("sanitize_output");
