FreePBX 2.11 + Debian 8 (Jessie)

When installing FreePBX 2.11 + Asterisk 11.20.0 on Debian 8 (Jessie) instead of Debian 7 (Wheezy), I get a massive numbers of:

PHP Notice: Undefined offset: 8192 in /var/www/html/admin/libraries/utility.functions.php on line 383

What is this indicative of and what can be done to eliminate them?

so the line

$txt = sprintf("%s] (%s:%s) - %s", $errortype[$errno], $errfile, $errline, $errstr);

known error types:

        $errortype = array (
                E_ERROR                                 => 'ERROR',
                E_WARNING                               => 'WARNING',
                E_PARSE                                 => 'PARSE_ERROR',
                E_NOTICE                                => 'NOTICE',
                E_CORE_ERROR                    => 'CORE_ERROR',
                E_CORE_WARNING                  => 'CORE_WARNING',
                E_COMPILE_ERROR                 => 'COMPILE_ERROR',
                E_COMPILE_WARNING               => 'COMPILE_WARNING',
                E_USER_ERROR                    => 'USER_ERROR',
                E_USER_WARNING                  => 'USER_WARNING',
                E_USER_NOTICE                   => 'USER_NOTICE',
                E_STRICT                                => 'RUNTIM_NOTICE',

the error 8192 is E_DEPRECATED. which isn’t in the list above and is new as of PHP 5.3.0

For PHP 5.3 you need FreePBX 12+

It appears PHP 5.4.45 is being installed under Debian 7 (Wheezy) -> No “Undefined offset: 8192:…” messages

It appears PHP 5.6.14 is being installed under Debian 8 (Jessie) -> Massive “Undefined offset: 8192:…” messages

What will be the effect of simply ignoring these messages under Debian 8 (Jessie)?

If you are using a newer version of PHP I suggest you use 12+. Most things will probably be OK but you may run in to random issues and quirks that may affect usability and stability.

You can add


to the above array and see what the actual error is.

The 8192 errors are only occurring during the install of FreePBX 2.11 (not during the use of FreePBX 2.11).

It’s not clear to me how I would add:




during the install process.

Hold on…

I think I’ve figured out how to add the line with sed after the install archive has been extracted.

I’ll report back what I find.




added to the $errortype array as you suggested, there are no

PHP Notice: Undefined offset: 8192 in /var/www/html/admin/libraries/utility.functions.php on line 383

messages displayed. Given that, is it safe to assume this is an innocuous message that can be ignored?
