为什么我在这个 PHP 生成行的末尾有一个 ctrl-J？

Question

我正在尝试从 PHP 生成 Java WebStart JNLP 文件。我会把整个代码放在最后，但我的具体问题是这行 PHP：

<property name="jnlp.versionEnabled" value="true" />
<?php
     echo "<property name=\"javaws.username\" value=\"" . $userid . "\" />"  
?>
<property name="server.port" value="3000" />

经过一番挣扎后，我发现 PHP 生成的行最后带有一个 ctrl-J。这完全搞砸了Webstart。为什么要这样做，我该如何阻止它？ PHP 的执行环境是 OpenSolaris 上的 PHP5。

此文件的完整代码如下供参考。 （Windows部分不用管，我是在Mac上工作的。等mac部分正常工作后我会修复它。）

Answer 1

将您的编辑器设置为不生成或保存 .php 文件，并在末尾添加一个新行。

Answer 2

通过将不需要的 nl ​​移到文件末尾的 heredoc 格式解决，这很烦人但无害。

Answer 3

这可能有效：

<property name="jnlp.versionEnabled" value="true" />
<?php echo "<property name=\"javaws.username\" value=\"" . $userid . "\" />";?>  
<property name="server.port" value="3000" />

另外，该行的末尾不应该有; 吗？
