在深入研究PHP 用户贡献的注释后，我找到了大部分解决方案。然后我扩展了我发现的内容并将其封装在一个函数中。它剥离<body></body>标签，呼应自己的可定制样式，然后phpinfo()是<div id='phpinfo'></div>.
function embedded_phpinfo()
{
ob_start();
phpinfo();
$phpinfo = ob_get_contents();
ob_end_clean();
$phpinfo = preg_replace('%^.*<body>(.*)</body>.*$%ms', '$1', $phpinfo);
echo "
<style type='text/css'>
#phpinfo {}
#phpinfo pre {margin: 0; font-family: monospace;}
#phpinfo a:link {color: #009; text-decoration: none; background-color: #fff;}
#phpinfo a:hover {text-decoration: underline;}
#phpinfo table {border-collapse: collapse; border: 0; width: 934px; box-shadow: 1px 2px 3px #ccc;}
#phpinfo .center {text-align: center;}
#phpinfo .center table {margin: 1em auto; text-align: left;}
#phpinfo .center th {text-align: center !important;}
#phpinfo td, th {border: 1px solid #666; font-size: 75%; vertical-align: baseline; padding: 4px 5px;}
#phpinfo h1 {font-size: 150%;}
#phpinfo h2 {font-size: 125%;}
#phpinfo .p {text-align: left;}
#phpinfo .e {background-color: #ccf; width: 300px; font-weight: bold;}
#phpinfo .h {background-color: #99c; font-weight: bold;}
#phpinfo .v {background-color: #ddd; max-width: 300px; overflow-x: auto; word-wrap: break-word;}
#phpinfo .v i {color: #999;}
#phpinfo img {float: right; border: 0;}
#phpinfo hr {width: 934px; background-color: #ccc; border: 0; height: 1px;}
</style>
<div id='phpinfo'>
$phpinfo
</div>
";
