Question

我已经看过其他人的问题，但看不到任何相同的内容，所以如果我错过了一个就道歉。

我在开发它的同时在一个子目录中创建了一个站点，然后将其移动到根目录，将其移动到根目录，通过php停止工作访问MySQL数据库。它停止的特定代码行是

$pdo=new PDO("mysql:dbname=NAME;host=127.0.0.1","USERNAME","PASSWORD");

一旦脚本移动到根目录外的单个目录，该脚本就可以正常工作。任何想法可能是什么问题？

您应该始终检查对数据库的所有调用的结果，以便将该行代码更改为

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.example.com"]];
request.HTTPMethod = @"POST";
request.HTTPBody = body;
[request setValue:@"someValue" forHTTPHeaderField:@"someField"];

这应该显示尝试连接数据库时生成的错误。
