Remove whitespace from HTML

Answer 1

$html = preg_replace('~>\s+<~', '><', $html);

But I don't see the point of this. If you're trying to make the data size smaller, there are better options.

Answer 2

As gpupo's post provided the cleanest solution for many different types of spacing formatting's. However, a minor but important piece was forgotten at the end! A final string trim :-p

Below is a tested and working solution.

function compress_html($content)
{
    $i       = 0;
    $content = preg_replace('~>\s+<~', '><', $content);
    $content = preg_replace('/\s\s+/',  ' ', $content);

    while ($i < 5)
    {
        $content = str_replace('  ', ' ', $content);
        $i++;
    }

    return trim($content);
}

//...
public function compressHtml($content)
{
    $content = preg_replace('~>\s+<~', '><', $content);
    $content = preg_replace('/\s\s+/', ' ', $content);
    $i = 0;
    while ($i < 5) {
        $content = str_replace('  ', ' ', $content);
        $i++;    
    }

    return $content;
}
