In Windows (WAMP) I have an index.php like this

在Windows（WAMP）中，我有一个像这样的index.php

<?xml version="1.0" encoding="utf-8"?>
<?php
    // ...
?>

and it works as expected.
Now I've just configured a LAMP on Ubuntu and the same file (when invoked from a browser) gives me an error. Looking in error.log I've found

它按预期工作。现在我刚刚在Ubuntu上配置了一个LAMP，同一个文件（从浏览器调用时）给了我一个错误。查看error.log我发现了

PHP Parse error: syntax error, unexpected T_STRING in /var/www/test/index.php on line 1

PHP解析错误：语法错误，第1行/var/www/test/index.php中的意外T_STRING

If I remove first line everything works fine.
What's wrong? Why this works on Windows and not on Linux?
Could this be caused from a particular extension?

如果我删除第一行一切正常。怎么了？为什么这适用于Windows而不适用于Linux？这可能是由特定的扩展引起的吗？

#1

It sounds like you have short tags enabled, which will cause PHP to try and parse what comes after <?.

听起来你启用了短标签，这会导致PHP尝试解析<？后面的内容。

Set the config option short_open_tag in php.ini to 0 or Off and restart Apache.

将php.ini中的config选项short_open_tag设置为0或Off并重新启动Apache。

#2

Did you check if short tags are enabled/disabled on php.ini?

您是否检查过php.ini上是否启用了短标签？

#3

It's not a good idea to work with XML as a string.

将XML作为字符串使用并不是一个好主意。

You should use php XML libraries like http://de.php.net/manual/en/book.dom.php

您应该使用PHP XML库，如http://de.php.net/manual/en/book.dom.php
