php中自定义函数dump查看数组信息类似var_dump_php技巧

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 = "

n"; <br>if ($label != '') { <br>$content .= "<strong>{$label} :</strong>n"; <br>} <br>$content .= htmlspecialchars(print_r($vars, true)); <br>$content .= "n

n";
} else {
$content = $label . " :n" . print_r($vars, true);
}
if ($return) { return $content; }
echo $content;
return null;
}
