标头函数中的PHP变量 [英] PHP variable in header function

问题描述

我正在尝试使用标头功能通过URL传递变量，以作为重定向页面的一种方式.但是，当页面被重定向时，它将传递实际的变量名称，而不是与变量关联的值.我是PHP的新手，并且不完全了解语法，因此，请您对执行此操作的正确方法作进一步说明.

I am attempting to pass variables through the URL using the header function as a way to redirect the page. But when the page is redirected it passes the actual variable names rather than the values associated with the variables. I am new to PHP and do not fully understand the syntax so any further explanation as to the proper way to do this would be much appreciated.

header('location: index.php?id=".$_POST[ac_id]."&err=".$login."');

推荐答案

您要:

header("Location: index.php?id=".$_POST['ac_id']."&err=".$login);

您在此字符串中组合了'和"，这就是为什么它无法正确插入变量的原因.在上面的示例中，您严格使用"打开字符串，并将变量与字符串连接.

You were combining ' and " in this string, which is why it couldn't interpolate the variables properly. In my example above, you are strictly opening the string with " and concatenating the variables with the string.
