PDO MySQL prepared INSERT syntax error - php

Question

Have seen tons of similar questions but still can't find out what's going on.
I'm using PHP's PDO to prepare a statement like that:
try{
$statement = $db->prepare("INSERT INTO $date (name, surname, email, phone, comment) VALUES (:name, :surname, :email, :phone, :comment)");
$statement->bindParam(':name', $name);
$statement->bindParam(':surname', $surname);
$statement->bindParam(':email', $email);
$statement->bindParam(':phone', $phone);
$statement->bindParam(':comment', $comment);
$statement->execute();
}
catch(PDOException $e){
die("Connection to database failed: " . $e->getMessage());
}
Have tried escaping everything with [] and specifying the database name before table name, but keep getting
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in
your SQL syntax; check the manual that corresponds to your MySQL server
version for the right syntax to use near '2017-08-11 (name, surname, email,
phone, comment) VALUES ('Test', 'Test', 'Test#' at line 1

Answer 1

INSERT INTO $date
It seems that there is a 2017-08-11 in $date var.
If you want to insert data into '2017-08-11' table, it should be escaped with ` symbol
try{
$statement = $db->prepare("INSERT INTO `$date` (name, surname, email, phone, comment) VALUES (:name, :surname, :email, :phone, :comment)");
$statement->bindParam(':name', $name);
$statement->bindParam(':surname', $surname);
$statement->bindParam(':email', $email);
$statement->bindParam(':phone', $phone);
$statement->bindParam(':comment', $comment);
$statement->execute();
}
catch(PDOException $e){
die("Connection to database failed: " . $e->getMessage());
}

Answer 2

Assuming that 2017-08-11 is a table name, simply encase it in backticks.
$statement = $db->prepare("INSERT INTO `$date` (name, surname, email, phone, comment) VALUES (:name, :surname, :email, :phone, :comment)");

Answer 3

sorry but you can't use special character when using the prepare statement, so what MySQL is actually seeing is INSERT INTO $date (name, surname, email, phone, comment) VALUES (:name, :surname, :email, :phone, :comment) which will trigger a syntax error.
here is a quick solution
try{
$db->query("INSERT INTO $date (name, surname, email, phone, comment) VALUES ($name, $surname, $email, $phone, $comment)");
}
catch(PDOException $e){
die("Connection to database failed: " . $e->getMessage());
}
