Mysql results as PHP named variables – Phpmyadmin

I have a table in mysql called site_settings that looks like this

Table in PHPMyAdmin

I am trying to store all of my website settings in mysql and want to pull them into PHP as variables.

I want to pull all values from the variable_name column as the $variable names in PHP and have their values set to whats in the variable_type column.

$site_name = Vexed

$registration_enabled = False

here is my code:

$sql = connect($database_address, $database_username, $database_password, $database);

$query = "SELECT * FROM site_settings";
$result = $sql->query($query);
//$row = $result->fetch_all(MYSQLI_ASSOC);

while($row = $result->fetch_assoc())
{
  $$row['variable_name'] = $row["variable_type"];
}

$arr = get_defined_vars();
print_r($arr);

the last two lines i am using to see if the variable have been created but i cant get it to work. the best result i have got so far is

    [Array] => Array
        (
            [variable_name] => Vexed
        )

Can anyone tell me where i am going wrong?

Thanks in advance to anyone who can help.

    What I think is happening is that when you call $$arr['variable_name'] it’s actually doing $$arr first (which evaluates to $Array after the string conversion), and then trying to assign into assign the [‘variable_name’] key into $Array.

    I would expect this minor modification to work:

    $sql = connect($database_address, $database_username, $database_password, $database);

$query = "SELECT * FROM site_settings";
$result = $sql->query($query);
//$row = $result->fetch_all(MYSQLI_ASSOC);

while($row = $result->fetch_assoc())
{
  $name = $row['variable_name'];
  $$name = $row["variable_type"];
}

$arr = get_defined_vars();
print_r($arr);

    Edit: I’ll also echo, that it’s a little bit weird to dynamically create variables in this way and it will make your code hard to follow.
