Public bug reported:
I just installed Ubuntu 18.04 LTS Release: 18.04 and the TCPDF packaged
with it doesn't work properly with the PHP 7.2.7 which came with the
same Ubuntu release:
# apt install php-tcpdf
php-tcpdf is already the newest version (6.2.13+dfsg-1ubuntu1).
# php -v
PHP 7.2.7-0ubuntu0.18.04.2 (cli) (built: Jul 4 2018 16:55:24) ( NTS )
Copyright (c) 1997-2018 The PHP Group

with Zend OPcache v7.2.7-0ubuntu0.18.04.2, Copyright (c) 1999-2018, by Zend
Technologies
gives me this when I try to download a PDF from a website hosted on Ubuntu
18.04 LTS:
Deprecated: The each() function is deprecated. This message will be suppressed
on further calls in /usr/share/php/tcpdf/tcpdf.php on line 16542
TCPDF ERROR: Some data has already been output, can't send PDF file
TCPDF was generating a valid PDF for download before the "upgrade" from Ubuntu
16 to Ubuntu 18 replaced PHP with a newer version that deprecates a function
which is needed. A forum post at
http://www.chronoengine.com/forums/posts/t105654/tcpdf-broken-on-php-7-2
suggests that TCPDF version 6.2.17 contains a fix for this issue, but Ubuntu
18.04 LTS is deploying an older version php-tcpdf 6.2.13+dfsg-1ubuntu1, which
simply refuses to play nice with the PHP 7.2.7-0ubuntu0.18.04.2 bundled into
the same release of Ubuntu.
