Php 标头位置在live server上不起作用，但在localhost上起作用

标头位置在live server上不起作用，但在localhost上起作用

这段代码一直工作到上周，但现在不再工作了

因此，我已经开始在localhost上进行测试。它像以前一样工作

我试图在代码顶部添加“ob_start（）”；不工作

请查看此代码并发表评论

我也遇到了这样的问题，所以我尝试了以下步骤来解决它。
1.在调用标题位置之前，删除或注释空格、回音、打印、错误报告。
2.删除php结束标记后的空格（在？>之后）
3.为此修改标题位置语法我通常做的是打开复制标题位置语法并粘贴它。在您的情况下，您应该尝试将标题代码更改为

header（'Location:innout-booking-step2.php'）（空格后：）
是否看到错误消息？请使用web服务器上的错误日志记录任何消息以获取线索。如果您的代码以前工作，但现在不工作，则说明发生了更改。找出那是什么，你就会发现你的问题所在；从我的代码来看，我不知道为什么echo会引起问题。。。
