如果您将它们作为纯文本回显，请在每个回显后添加换行符：

echo "\n";

如果您将它们回显到HTML（进入Web浏览器），请在每次回显后添加HTML <br>标记：

echo "<br>";

您也可以使用字符串连接

echo "Programming in PHP is fun" . "\n";
echo "Programming in PHP is fun" . "<br>";

或将换行符或<br>标记添加到字符串

echo "Programming in PHP is fun\n";
echo "Programming in PHP is fun<br>";

php打印语句在单独的行中
