PHP:“语法错误，意外的T_字符串”与mail（）

我有一个简单的脚本，可以用PHP发送邮件：

mail( "$webmaster_email", "RSVP from WC Entry Form",
   "From: $email, \n Name: $firstname $lastname \n 
   Phone Number: $phone \n 
   Address: $postal \n );
header( "Location: $thankyou_page" );

但我得到了解析错误：语法错误，意外的T_字符串

我不确定这是什么，谷歌没有给我任何明确的答案

有人知道为什么会这样吗

mail( "$webmaster_email", "RSVP from WC Entry Form",
   "From: $email, \n Name: $firstname $lastname \n 
   Phone Number: $phone \n 
   Address: $postal \n ");
header( "Location: $thankyou_page" );

您刚刚忘记了“”。

将代码更改为

mail( "$webmaster_email", "RSVP from WC Entry Form",
   "From: $email, \n Name: $firstname $lastname \n 
   Phone Number: $phone \n 
   Address: $postal \n ");
header( "Location: $thankyou_page" );

谢谢，伙计们，这应该是显而易见的
