php中自定义函数dump查看数组信息类似var_dump

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;
}
