GLPI is compatible with PHP 7.2 but not the bundled libraries (tcpdf and ZF) thus requires some patch.

Operating system: Linux localhost 3.10.0-693.5.2.el7.x86_64

On RHEL / CentOS, I recommend you use the RPM available in my repository, which use system libraries, which include needed patches for PHP 7.2

See https://blog.remirepo.net/post/2017/09/26/GLPI-version-9.2-en

But indeed, we need to patch these libraries, as part of the GLPI release process.

You need to pull GLPI from remi-test and dependencies from remi (and PHP from remi-php72)

Check php-tcpdf version (6.2.13-4 is the needed version for PHP 7.2) and php-zendframework-*

P.S. but out-of-topic here.
