当我在浏览器中打开它时，PHP文件是空白的。此外，当我打开源代码时，它也是空的。
这是 tutorial 我正在关注
以下是代码：

答案 0 :(得分：0)
你在这一行上有错误
if (strlen($getemail) >= 7) && (strstr($getemail, "@")) && (strstr($getemail, ".")) {
必须是if ((strlen($getemail) >= 7) && (strstr($getemail, "@")) && (strstr($getemail, "."))) {
另外，浏览器中的源代码会显示html代码而不是php php是服务器端，因此它的代码在服务器内，浏览器无法看到
