What are some best practices for handling file and folder permissions in PHP to avoid safe_mode issues?

When handling file and folder permissions in PHP to avoid safe_mode issues, it is important to ensure that the correct permissions are set for files and folders to prevent unauthorized access. One way to do this is by using the `chmod()` function to set the appropriate permissions for files and folders.

// Set file permissions to 0644 (read and write for owner, read for others)
chmod('/path/to/file.txt', 0644);

// Set folder permissions to 0755 (read, write, and execute for owner, read and execute for others)
chmod('/path/to/folder', 0755);
