Are there any specific best practices to follow when migrating a website from Abyss Web Server to Apache 2 in terms of PHP code compatibility?

When migrating a website from Abyss Web Server to Apache 2, one common issue is related to PHP code compatibility. To ensure smooth migration, it is important to check for any PHP functions or configurations that may differ between the two servers. One specific best practice is to update any deprecated functions or settings to ensure compatibility with Apache 2.

// Before migration:
// Deprecated function in Abyss Web Server
mysql_connect($host, $username, $password);

// After migration:
// Updated function for Apache 2
mysqli_connect($host, $username, $password);
