使用自定义代码生成多行的php代码
对于Ex- 如果用户在文本框中输入，如 第101册总计第2册 接收编号-500 totalrec-2 优惠券-700 totalcoup-2 然后输出如下表所示 在此表中，优惠券编号始终是唯一的。收据编号为两次bcoz每张收据分配两张优惠券。 对于Ex- 图书收据优惠券 101 500-700 101 500-701 101-501-702 101-501-703 102-502-704 102-502-705 102-503-706 102-503-707 现在是第二次输入时 图书编码=800 图书编号2=802 接收代码=1600 临时收据=1602 耦合码=1800使用自定义代码生成多行的php代码,php,mysql,pdo,Php,Mysql,Pdo,对于Ex- 如果用户在文本框中输入，如 第101册总计第2册 接收编号-500 totalrec-2 优惠券-700 totalcoup-2 然后输出如下表所示 在此表中，优惠券编号始终是唯一的。收据编号为两次bcoz每张收据分配两张优惠券。 对于Ex- 图书收据优惠券 101 500-700 101 500-701 101-501-702 101-501-703 102-502-704 102-502-705 102-503-706 102-503-707 现在是第二次输入时 图书编码=800
临时优惠券=1802 然后生成如下输出 图书收据优惠券 801 -1601 1801 801 -1601 -1802 801 -1602 -1803 801 -1602 -1804 802 -1603 -1805 802 -1603 -1806 802 -1604 -1807 802-1604-1808 我尝试下面的代码，但工作不正常

您得到了什么输出？如果不知道“工作不正常”是什么意思，帮助你有点困难。知道输出应该是什么也很有用。我在上面更新了我的输出。plz帮助。这是一个与最初发布的问题不同的问题。关闭这个问题，开始一个新的问题，提供所有你能提供的信息，在你的代码中添加日志来显示各种变量的值（在你的问题中也给出这个值）我直接创建这个输出不是从代码…但是我需要从上面输入的代码中得到这个输出。。如果你这样做，我会很感激你。当你运行代码时，你得到了什么？循环每次迭代的相关变量值是多少？添加调试代码以查找错误。说“它进入一个无限循环”而不提供任何实际发生的背景是没有任何帮助的没有先生，现在这段代码工作正常，没有进入任何无限循环，但我的意思是上面的代码没有得到输出，因为我发送给你上面的输入…做一些调试日志，并张贴在这里！我不知道你在期待什么，你输入了什么值，你在使用什么代码或者其他什么。它从一个无限循环一直到工作，你没有告诉我你做了什么或你在使用什么先生，我现在发布我的完整代码…这正是我想要的…但问题是我在收据和优惠券代码循环中使用if-else ok…第一次当数据库为空时，它会生成正确的输出…正如我想要的…ok
