Call to undefined function mysqli()

Question

The issue occurs with this code

Answer 1

The error message is crystal clear: there is no such function in PHP and never has been. There is only a function called mysqli_connect() and class called mysqli. But classes are not functions and have different syntax to handle

It means that, according to the error message, somewhere in the /var/www/html/actions/create_account.php on line 29 there is an improper call to mysqli
