PHP-如何从其他文件访问其他变量？
我有两个php文件：index.php和search_server.php。 我需要从index.php访问$pilihdomain，然后在search_server.php中使用它，在这行PHP-如何从其他文件访问其他变量？,php,variables,get,Php,Variables,Get,我有两个php文件：index.php和search_server.php。 我需要从index.php访问$pilihdomain，然后在search_server.php中使用它，在这行$resp=$uclassify->classify（$tweet['text']，$pilihdomain，'herlambangp'） 最后一天，我使用了require ang全局变量，但它似乎是错误的。 提前谢谢 //index.php <head> <title>Twi
$resp=$uclassify->classify（$tweet['text']，$pilihdomain，'herlambangp'）
最后一天，我使用了require ang全局变量，但它似乎是错误的。

您应该有一个外部“配置”或“设置”文件，其中包含您在站点中全局需要的变量。然后，在需要这些配置设置的所有页面中包含该外部文件
除了pilihdomain，我还为您将db设置放在这个文件中，因为您确实应该创建这些共享设置，而不是在每个需要它们的脚本中重新定义它们

使用会话变量。
它们很容易设置，您可以跨页面使用它们。很抱歉响应太晚，我会尽快尝试您的建议。谢谢：）你好@Steven，我已经尝试了代码，但是$pilihdomain尚未访问，这是错误消息“致命错误：未捕获的异常‘uClassifyException’，消息为‘文本应如何分类？’？似乎没有指定ClassifierName！'在C:\xampp\htdocs\kejar\code\uClassify.php:107堆栈跟踪：#0 C:\xampp\htdocs\kejar\code\search\u server.php（62）：uClassify->classify（'，，lah myn，，，“@…'，NULL，'herlambangp'）#1{main}在C:\xampp\htdocs\kejar code\uClassify.php的第107行抛出“@herlambangpermadi-该错误可能是由于没有post数据可设置$pilihdomain.
。如果未设置$\u POST['cmake']
，我修改了上面的答案，将$pilihdomain
设置为空字符串（“”）。您好@Steven，感谢您的回复。settings.php中是否缺少某些内容？我发现“解析错误：语法错误，意外的'；'”消息，我还不明白如何在php中使用“？”。谢谢史蒂文，再次编辑。我有一个额外的分号。嗨，在我的问题案例中有使用会话的例子吗？在你的例子中有很多代码，所以我不想给你的代码举个例子。不过，本文应该解释您需要了解的有关会话变量的所有信息：。正如我所说的，这些变量非常容易设置，了解它们的工作原理比我编写解决方案更值得。教一个人钓鱼等等。MySQLPDO关注点分离
