Php exit() function print message

本文关键字：打印消息函数 exit Php | 更新日期: 2023-09-26

你能帮我吗?我有这样一行:

$orderRequest = new CreateOrderRequest(null, "BTC", null, $currency, $amount, $orderDescription, "en", $callbackUrl, $successUrl, $cancelUrl);

我需要打印:$orderRequest

我是这样做的:

exit("orderRequest: {$currency} {$amount}; {$orderDescription}; {$callbackUrl}; {$successUrl}; {$cancelUrl}");

也许有更简单的方法来做到这一点?

这里有一个简化的方法:

echo '<pre>'; // easy way to improve print_r layout (newlines)
print_r($orderRequest); // can print objects and arrays, while exit() doesn't
exit(); // optional, depending if you want to terminate program execution

同样，{$currency}的花括号只在像echo "{$currency['key']}";

这样的双引号字符串中打印数组键时才需要。
