What are the common pitfalls when setting and accessing variables like $row in PHP scripts?

Common pitfalls when setting and accessing variables like $row in PHP scripts include using undefined variables, not properly initializing variables, and potential naming conflicts with existing variables. To avoid these issues, always initialize variables before using them, ensure variables are properly defined and named uniquely to prevent conflicts. 

// Initialize $row variable before using it
$row = null;

// Accessing $row variable safely
if(isset($row)) {
    // Do something with $row
    echo $row;
} else {
    echo "Row is not set.";
}
