works but brakes lines before "class", "value" etc

view-source example

Why? Should be all in one line with no brakes, no?

Same

the performance is minimal, does it still work?

This is a bug in the external Minify_HTML library:
If You add this test to this class ...

<?php

namespace Minify\Test;

use Minify_HTML;

class MinifyHTMLTest extends TestCase
{
    public function test1() { }

    public function test2() { }

    public function tagProvider()
    {
        return [
            ['<label for="email"></label>'],
            ['<input type="hidden">'],
        ];
    }

    /**
     * @dataProvider tagProvider
     */
    public function testNoNewLineAfterOpenTagName($htmlTag)
    {
        $actual = Minify_HTML::minify($htmlTag, array(
            'cssMinifier' => array('Minify_CSSmin', 'minify'),
            'jsMinifier' => array('JSMin\\JSMin', 'minify'),
        ));

        $this->assertEquals($htmlTag, $actual);
    }
}

and change this line

$this->_html = preg_replace('/(<[a-z\\-]+)\\s+([^>]+>)/iu', "$1\n$2", $this->_html);

to this:

$this->_html = preg_replace('/(<[a-z\\-]+)\\s+([^>]+>)/iu', "$1 $2", $this->_html);

it will parse correctly (but probably something else will fail to work properly 😄 )
