我有一个简单的问题，我目前正在运行Drupal的测试网站。我有一个模块，编写并支持最高6.16版本的测试站点，当我启用模块时，我目前想在崩溃时使用该模块。
我想知道可以查看哪些基本元素以确保代码兼容和/或是否需要更改。
该模块提供了将CRM集成到Drupal for SSO中。
我想是否有其他人遇到过创建模块来弥合他们可能指向正确方向的系统之间的差距。
这是我启用模块时收到的错误：
Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /homepages/22/d223624283/htdocs/drupal6/sites/all/modules/convio/convio.module on line 104
这是名为convio.module的文件中的代码，它给我一个问题：

新评论后更新：
你还在使用PHP 4吗？这将解释错误 - 方法链接（意味着直接在应该返回对象的函数上使用' - ＆gt;'运算符），仅支持PHP 5，IIRC。
如果是这种情况，正确的解决方案是切换到PHP 5！
作为临时解决方案，您可以搜索“ - ＆gt;”所有位置operator直接用于函数/方法结果（functionCall()->...）并通过另一个变量插入分隔。 请注意，我不建议这样做 - 不推荐使用PHP 4，并且不再接收安全更新。在它上面运行一个生产环境是不可能的！
原始回答：
该代码中唯一的T_OBJECT_OPERATOR（' - ＆gt;'）似乎在：
if (ConvioConfiguration::getInstance()->isEnabled()) { ...
因此您可能希望将该行更改为以下内容：
$convioConfiguration = ConvioConfiguration::getInstance();
if (is_object($convioConfiguration) && $convioConfiguration->isEnabled()) { ...
