Code Php的语法错误

Question

我不断用这行代码获得此语法错误。

$subject = 'Message - General Inquiry from '.$field_name' with the email of '.$field_email;

有人可以帮忙吗？

Answer 1

$subject = 'Message - General Inquiry from '.$field_name.' with the email of '.$field_email;

Answer 2

.之后您错过了$field_name运算符。另一方面，如果您只使用插值，则无需担心.运算符：

$subject = "Message - General Inquiry from $field_name with the email of $field_email";
