好的，所以我是 PHP 新手，并尝试制作一个脚本，该脚本从我拥有的 mysql 数据库中获取所有股票价格数据，然后查看在盘后交易期间股票价格是否上涨（通过比较一个当天的收盘价与第二天的开盘价）。我已经设置了一些这样的脚本，但是由于某种原因，这个脚本没有将数据复制到我的 sql 数据库中，我完全不知道为什么它不会。当我在整个过程中设置 echo 语句时，我发现我的代码似乎到处都在执行，但数据没有传输。任何帮助是极大的赞赏。

你错过,了,sellValue='$sellValue'trueValue='$trueValue' 它应该是,sellValue='$sellValue',trueValue='$trueValue'
