我们可以自定义一个函数来实现变量的格式化输出,代码如下:
function dump($vars, $label = '', $return = false) { if (ini_get('html_errors')) { $content = "\n"; if ($label != '') { $content .= "{$label} :\n"; } $content .= htmlspecialchars(print_r($vars, true)); $content .= "\n\n"; } else { $content = $label . " :\n" . print_r($vars, true); } if ($return) { return $content; } echo $content; return null; }
