Question

好的，所以我是PHP的新手并尝试制作一个脚本，该脚本从我拥有的股票价格的mysql数据库获取所有数据，然后查看在盘后交易中是否有股价上涨（比较一天的收盘价和第二天的开盘价。我已经设置了一些像这样的脚本工作，但由于某种原因，这个脚本没有将数据复制到我的sql数据库中，我完全难以理解为什么它不会。当我设置echo语句时，我发现我的代码似乎在任何地方执行但数据没有传输。非常感谢任何帮助。

Answer 1

您错过了, ,sellValue='$sellValue'trueValue='$trueValue' 它应该是,sellValue='$sellValue',trueValue='$trueValue'

PHP没有转移到mysql数据库
