What are the potential issues when trying to adapt Wbb 2.3.6 to PHP 7?

One potential issue when trying to adapt Wbb 2.3.6 to PHP 7 is that the code may contain deprecated functions or syntax that are no longer supported in PHP 7. To solve this, you will need to update the deprecated functions and syntax to their PHP 7 equivalents.

// Deprecated function in Wbb 2.3.6
mysql_query($query);

// Updated function for PHP 7
mysqli_query($connection, $query);
