What are the potential risks of changing folder permissions when using the copy() function in PHP?

When using the copy() function in PHP to copy files, changing folder permissions can potentially introduce security risks by allowing unauthorized access to the files. To solve this issue, it is important to ensure that the folder permissions are set appropriately before using the copy() function. 

// Set folder permissions to restrict access
chmod('/path/to/folder', 0755);

// Use copy() function to copy file
if (copy('/path/to/source/file', '/path/to/destination/file')) {
    echo "File copied successfully.";
} else {
    echo "Failed to copy file.";
}
