变量声明： -

# Get object's boolean field and toggle it
# @param [Object] mongoid object 
# @param [String, Symbol] flag
# @example

语法错误意外＆＃39; $ firstname＆＃39; （T_VARIABLE）第21行

Answer 1

试试这个

 $sql = "INSERT INTO people (firstname, surname, id,   
 faculty_of_study, enrolled_course, gender, password, telephone_no, 
email_address) VALUES ('$firstname', '$surname', '$id',  
'$faculty_of_study',
'$enrolled_course', '$gender','$password', '$telephone_no','$email_address')";

Answer 2

试试这个

$sql = "INSERT INTO people (firstname, surname, id,faculty_of_study, enrolled_course, gender, password, telephone_no, email_address) VALUES ('".$firstname."', '".$surname."', '".$id."', '".$faculty_of_study."',  '".$enrolled_course."', '".$gender."','".$password."', '".$telephone_no."', '".$email_address."')";

并在VALUES之前删除分号。
