这个很早就有了，比php自带的var_dump好用多了。

复制代码 代码如下:

function dump($vars, $label = '', $return = false) {

if (ini_get('html_errors')) {

$content = "<pre>n";

if ($label != '') {

$content .= "<strong>{$label} :</strong>n";

}

$content .= htmlspecialchars(print_r($vars, true));

$content .= "n</pre>n";

} else {

$content = $label . " :n" . print_r($vars, true);

}

if ($return) { return $content; }

echo $content;

return null;

}
