Are there specific best practices or guidelines for writing PHP scripts that can help prevent compatibility issues when moving to a new server?

When moving PHP scripts to a new server, it's important to follow best practices to prevent compatibility issues. One common issue is the use of deprecated functions or features in PHP versions. To avoid this, always use up-to-date PHP functions and syntax, and regularly update your code to be compatible with the latest PHP versions. 

// Example of using a deprecated function (mysql_connect)
// Update to use mysqli or PDO instead

// Deprecated code
$connection = mysql_connect('localhost', 'username', 'password');

// Updated code using mysqli
$connection = mysqli_connect('localhost', 'username', 'password', 'database_name');
