Fatal error: Uncaught mysqli_sql_exception: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''crud' ('first name', 'last name', 'phonenumber', 'email', 'password', 'birth...' at line 1 in C:\xampp\htdocs\crud\regForm.php:15 Stack trace: #0 C:\xampp\htdocs\crud\regForm.php(15): mysqli_query(Object(mysqli), 'INSERT INTO 'cr...') #1 {main} thrown in C:\xampp\htdocs\crud\regForm.php on line 15


My code:

<?php
include 'connect.php';
if(isset($_POST['submit'])){
  $fname=$_POST['fname'];
  $lname=$_POST['lname'];
  $pnum=$_POST['pnum'];
  $email=$_POST['email'];
  $pass=$_POST['pass'];
  $bday=$_POST['bday'];
  $gender=$_POST['gender'];

  $sql = "INSERT INTO 'crud' ('first name', 'last name', 'phonenumber', 'email', 'password', 'birthday', 'gender')
  VALUES('$fname', '$lname', '$pnum', '$email', '$pass', '$bday', '$gender')";

  $result = mysqli_query($con,$sql);
  if($result){
    echo "DATA INSERTED SUCCESSFULLY";
  }else{
    die(mysqli_error($con));
  }
}
?>


What I have tried:

What are the values in each of those parameters?

Try removing the single quotes from 'crud'; (just a guess).

Does not MariaDB use ` instead of ' to quote fieldnames?

That should be a solution.
