How can file permission errors, such as "Permission denied," be resolved when uploading files in PHP?

File permission errors like "Permission denied" can be resolved by ensuring that the directory where the file is being uploaded has the correct permissions set. This can be done by changing the directory permissions to allow the PHP script to write to it. Additionally, checking the ownership of the directory and file can help resolve permission issues. 

// Set the correct permissions for the directory where the file will be uploaded
chmod('/path/to/upload/directory', 0777);

// Check if the directory permissions have been set correctly
if (is_writable('/path/to/upload/directory')) {
    // Upload the file
    move_uploaded_file($_FILES['file']['tmp_name'], '/path/to/upload/directory/' . $_FILES['file']['name']);
    echo 'File uploaded successfully!';
} else {
    echo 'Permission denied. Unable to upload file.';
}
