function formatException(Exception $e)
  {
    return "Error {$e->getCode()}: {$e->getMessage()} " .
          "(line: {$e->getline()} of {$e->getfile()})";
  }

 

 

try:catch block  Where do i put the function?

try {
   $answer=average($myString); 
   echo $answer."<br />";
} 
catch (Exception $em) 
{
    echo $em."<br />";
}
