What are some best practices for handling sensitive operations, such as deleting entries, in PHP applications?

When handling sensitive operations like deleting entries in PHP applications, it is crucial to implement proper security measures to prevent unauthorized access or accidental data loss. Some best practices include using prepared statements to prevent SQL injection attacks, implementing role-based access control to restrict user permissions, and confirming the action with a confirmation prompt before executing the operation. 

// Example of deleting an entry with proper security measures

// Check if user has permission to delete
if($user->isAdmin()) {
    // Get entry ID from request
    $entryId = $_POST['entry_id'];

    // Confirm action with user
    if(confirmDelete()) {
        // Use prepared statement to delete entry
        $stmt = $pdo->prepare("DELETE FROM entries WHERE id = ?");
        $stmt->execute([$entryId]);
        echo "Entry deleted successfully.";
    } else {
        echo "Delete action cancelled.";
    }
} else {
    echo "You do not have permission to delete entries.";
}

function confirmDelete() {
    // Display confirmation prompt to user
    // Return true if user confirms, false if not
}
