What are the common pitfalls to avoid when transitioning PHP code to newer versions like PHP 8.2?

One common pitfall when transitioning PHP code to newer versions like PHP 8.2 is using deprecated functions or features that have been removed in the new version. To avoid this, it's important to update your codebase and replace deprecated functions with their modern equivalents. Additionally, make sure to check for any syntax changes or new features introduced in PHP 8.2 that may affect your code. Example code snippet for replacing a deprecated function:

// Deprecated function usage
$oldValue = mysql_real_escape_string($value);

// Updated code using mysqli_real_escape_string
$newValue = mysqli_real_escape_string($connection, $value);
