Laravel 4.2检查附件是否存在

Question

I have the following code:

$message->to($user->W_EMAIL_ADDRESS, '')
        ->subject($user->W_SUBJECT.$user->W_SITE_ADDRESS);

Is there any possible way to check the existence of the file before put the following line?

$message->attach($user->W_PATH_FILE);

many thanks

Have a look at filesystem functions that PHP offers here: http://php.net/manual/en/ref.filesystem.php

You can check if a given file exists and is readable by PHP with the following:

if(is_readable($user->W_PATH_FILE)) {
  $message->attach($user->W_PATH_FILE);
}
