关于PHP中URL参数的传递问题
最近同事在维护一个PHP的网站，这个网站是很久以前开发的，之前负责维护的员工已经离职了，现在维护任务分配给我们信息技术部了，主要由这个同事负责。
现在要求把网站迁移到一个新的机房，所以需要重新配置一个主机，然后把网站移过来，折腾了几天，一切都OK了，但是在测试的时候，发现一个问题，就是所有的页面，如果地址栏中有参数，需要查询数据库的，那么这个页面就查不到数据，但是数据库连接是正常的。最开始以为是程序问题，但是后来发现只要有参数传递的页面都有这个问题，于是就推测不是程序问题，程序没有修改过，那么只可能是配置问题，但是配置没发现什么问题，最后还是只能借助google了。
最后查询的结果是php的版本之间有差别，有些默认开启的配置在php5中被关闭了，如在php4以前url后面的参数是自动填充到参数名称对应的变量中，如果url地址为view.php?id=1 ，那么在view.php页面中可以直接使用$id来去得参数id的值，这个对应的配置项为register_globals，在php4之前的版本中，默认是开启的，后面的版本是关闭的。于是就到C盘的
windows目录里面找到php.ini文件，将register_globals的值改为On，然后再测试，发现问题解决了。
为这个问题折腾了不少时间，特意记下来，以便下次再折腾。
