Declaration of a custom function in another custom function

Question

My 1st function:

function db_connect_error_mail ($txt) {
mail(admin_email,mail_subject01,$txt);} //1st three variables come from constants at config.php

and 2nd function:

function connectdb() {
  $dbc = mysqli_connect (db_host, db_user, db_password, db_name); //variables come from constants at config.php
  if (!$dbc) 
{
$txt = mysqli_connect_errno().mysqli_connect_error();
db_connect_error_mail($txt);
unset ($txt);
die('custom error message to inform viewer');
} else 
    {
        return $dbc;
    }
}

My question:

Is it okey in index.php just to call connectdb()? If db connection couldn't be set, will I get an email also? (assume that server's mail function works all time)

Guess, yeah, provided you are including the `config.php` in `index.php`. :) — Praveen Kumar Purushothaman, Feb 01 '13 at 07:50
The answer is 42 (no, you will not get an email since you use `die` - and this stops the execution of your script). — Vlad Preda, Feb 01 '13 at 07:54
You won't get an email, as soon as you call die(), the script will stop. Place the die() after the unset('txt); — Tjoene, Feb 01 '13 at 07:54
thanks, I will place the die() after the unset('txt). Is there any other deficiency? — Andre Chenier, Feb 01 '13 at 08:00

If you will call die before db_connect_error_mail() then no, you won't receive your e-mail as die() function stops execution of any further code.

You might however call your die function after sending the error e-mail. this way you will get both: notification mail and an error message.
