What are the potential pitfalls of using RAM to store variables in PHP scripts, and how can these issues be addressed or avoided?

Potential pitfalls of using RAM to store variables in PHP scripts include the risk of running out of memory if too many variables are stored or if large amounts of data are being stored. To address this issue, it's important to properly manage variable scope and memory usage by only storing necessary data in RAM and freeing up memory when variables are no longer needed. 

// Example of properly managing variable scope and memory usage
function process_data($data) {
    // Process data here
    // Store only necessary variables in RAM
    $result = $data + 10;

    // Free up memory by unsetting variables that are no longer needed
    unset($data);

    return $result;
}
