So recently my code editor has been putting a line through File because it is going to removed in CakePHP 5

So here is an example of code that uses the deprecated methods and the suggested SplFileObject

Using File

public function createTempFile($print_content, $print_settings = [])
        if (isset($print_settings['temp_file'])) {
            $tempFile = $print_settings['temp_file'];
        } else {
            $tempFile = TMP . 'PrintTempFile.txt';

        $print_file = new File($tempFile, true, 0644);



Using SplFileObject

Note that to “close()” the file you assign the SplFileObject to null

Also there doesn’t appear to be an inbuilt chmod so you just have to use the PHP builtin

    public function createTempFile($print_content)
        $tempFile = TMP . sprintf( 'PrintTempFile-%s.txt', $this->action);

        $print_file = new SplFileObject($tempFile, 'w');
        chmod ($print_file->getRealPath(), 0666);


        $print_file = null;
