这个很早就有了,比php自带的var_dump好用多了。
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; }
