Give permission in to dynamically created file

                  $upPath = yourpath;
                    if(!file_exists($upPath)) 
                    {
                        $oldmask = umask(0);
                        mkdir($upPath, 0777, true);
                        umask($oldmask);
                    }  

Use the function chmod
chmod

$fp = fopen($file, 'w');
fwrite($fp, $content);
fclose($fp);
chmod($file, 0777); 

Use chmod() to set file permissions.

use:

private function writeFileContent($file, $content){
   $fp = fopen($file, 'w');
   fwrite($fp, $content);
   fclose($fp);
   chmod($file, 0777);  //changed to add the zero
   return true;
}
