What steps can be taken to troubleshoot and address speed issues in PHP scripts that are designed to run offline for hours at a time?

The speed issues in PHP scripts running offline for hours at a time can be addressed by optimizing the code for efficiency and performance. This can include reducing unnecessary loops, minimizing database queries, and optimizing algorithms to improve execution time. 

// Example code snippet to address speed issues in PHP scripts
// Optimize database queries by fetching only necessary data
$query = "SELECT id, name FROM users WHERE status = 'active'";
$result = mysqli_query($connection, $query);

// Use efficient algorithms to process data
while ($row = mysqli_fetch_assoc($result)) {
    // Process user data here
}

// Minimize unnecessary loops and operations
for ($i = 0; $i < count($data); $i++) {
    // Perform necessary operations on data
}
