这是脚本，它自己的工作，但是当我一起使用它时，它不会像它应该的那样工作。这里的问题是while循环内部的if条件应该从数据库中获取值，并根据$ watch的值的条件执行语句，这将在$ rajat中进一步使用。但while循环只运行一次。如果我运行while循环，如果语句分开，那么他们正在工作。这里可能是什么问题。预先感谢您的帮助....如果条件内部while循环不工作，而它单独工作

如何去除'while'结束支架'}'循环，尾括号在脚本的末尾。 – dbf 2013-05-01 22:10:14
根据发布的代码，在检查监视列表之前，您有一个额外的（不必要的）花括号。 – Scott 2013-05-01 22:10:16
或措辞不同：在while循环中没有if条件（它仅由三行组成）。 – hakre 2013-05-01 22:11:19
