通过Access-Control-Allow-Origin 表示您正在尝试在本地文件上执行Ajax。出于安全原因，这是禁止的。即使情况并非如此，您的PHP将无法运行，因为PHP受Web服务器支持，而不是Web浏览器。
您安装了Web服务器。您必须通过服务器请求您的页面，而不是直接从您的文件系统访问它们。
使用以 http：//开头的URL localhost /
您需要移动文件，使其位于服务器的 I have ready many of the other posts ppl have asked here about the origin not allowed blablabla, Now I have tried to add --Access-Control-Allow-Origin and enable apps and even disabled security but every time I try my button on the php page it just keeps stating Can anyone help me at all?

Origin null is not allowed by Access-Control-Allow-Origin means that you are trying to perform Ajax on a local file. This is forbidden for security reasons. Even if this was not the case, your PHP wouldn't run because PHP is supported by web servers, not web browsers.http://localhost/DocumentRoot (or reconfigure the server so that it can access them from their present location).
