推荐答案

PHP解析器错误需要一些习惯；如果它抱怨X行出现意外的情况"，请首先查看X-1行.在这种情况下，它不会告诉您在上一行的末尾忘记了分号，而是会抱怨接下来的if.

PHP parser errors take some getting used to; if it complains about an unexpected 'something' at line X, look at line X-1 first. In this case it will not tell you that you forgot a semi-colon at the end of the previous line , instead it will complain about the if that comes next.

您会习惯的:)
