php - 彩色 var_dump() 和错误

Question

如何将样式设置为 var_dump()功能和 PHP 错误样式，就像下一张图片一样？

目前我有下一个 View var_dump() (有 <pre>var_dump(...)</pre> ，没有它会全部在一行中)并且只是错误的纯文本。

我搜索了 PHP 彩色错误，var_dump样式，但找不到任何东西。

我使用 OpenServer 作为本地主机，在以前的版本中我有相同的错误样式，但现在只是纯文本。定制是真的吗？

使用此代码。我已经使用它很多年了。我什至不记得它最初来自哪里。

function var_dump_pretty($data, $label='', $return = false) {
    $debug = debug_backtrace();
    $callingFile = $debug[0]['file'];
    $callingFileLine = $debug[0]['line'];

    ob_start();
    var_dump($data);
    $c = ob_get_contents();
    ob_end_clean();

    $c = preg_replace("/\r\n|\r/", "\n", $c);
    $c = str_replace("]=>\n", '] = ', $c);
    $c = preg_replace('/= {2,}/', '= ', $c);
    $c = preg_replace("/\[\"(.*?)\"\] = /i", "[$1] = ", $c);
    $c = preg_replace('/  /', "    ", $c);
    $c = preg_replace("/\"\"(.*?)\"/i", "\"$1\"", $c);
    $c = preg_replace("/(int|float)\(([0-9\.]+)\)/i", "$1() <span class=\"number\">$2</span>", $c);

    // Syntax Highlighting of Strings. This seems cryptic, but it will also allow non-terminated strings to get parsed.
    $c = preg_replace("/(\[[\w ]+\] = string\([0-9]+\) )\"(.*?)/sim", "$1<span class=\"string\">\"", $c);
    $c = preg_replace("/(\"\n{1,})( {0,}\})/sim", "$1</span>$2", $c);
    $c = preg_replace("/(\"\n{1,})( {0,}\[)/sim", "$1</span>$2", $c);
    $c = preg_replace("/(string\([0-9]+\) )\"(.*?)\"\n/sim", "$1<span class=\"string\">\"$2\"</span>\n", $c);

    $regex = array(
        // Numberrs
        'numbers' => array('/(^|] = )(array|float|int|string|resource|object\(.*\)|\&amp;object\(.*\))\(([0-9\.]+)\)/i', '$1$2(<span class="number">$3</span>)'),
        // Keywords
        'null' => array('/(^|] = )(null)/i', '$1<span class="keyword">$2</span>'),
        'bool' => array('/(bool)\((true|false)\)/i', '$1(<span class="keyword">$2</span>)'),
        // Types
        'types' => array('/(of type )\((.*)\)/i', '$1(<span class="type">$2</span>)'),
        // Objects
        'object' => array('/(object|\&amp;object)\(([\w]+)\)/i', '$1(<span class="object">$2</span>)'),
        // Function
        'function' => array('/(^|] = )(array|string|int|float|bool|resource|object|\&amp;object)\(/i', '$1<span class="function">$2</span>('),
    );

    foreach ($regex as $x) {
        $c = preg_replace($x[0], $x[1], $c);
    }

    $style = '
