For me update php 7.1.1-1 cause problems with:

phpmyadmin

session_start(): open(SESSION_FILE, O_RDWR) failed: No such file or directory (2)

session_start(): Failed to read session data: files (path: )

zabbix gui

Re: [SOLVED] webapps broken with php 7.1

errors related to session creation is seems to be caused by the "PrivateTmp=true" in php-fpm.service. Every webapp on my pc is running in own php-fpm pool with own unix user and can't access files of other pool, to prevent problems (I saw conflicts because different pools used same name for session file of client) I had to make new tmp folders for each pool (using systemd *.mount files), like "/tmp/php-fpm-pma". It worked fine. But after update to php 7.1 pools no longer able to read /tmp (which looks kinda correct for "PrivateTmp=true", now I have no idea why it worked before), and each pool try reach his tmp folder inside php-fpm private folder (/tmp/systemd-private-...-php-fpm.service-...), which does not exist. The further the more it looks like a bad way to isolate pools, but I guess its fine.

solved

PS
phpldapadmin give unknown error which is related to deprecation of mcrypt function, its not yet removed, but webapp not working, this can be dirty fixed by adding

        if ($errno == E_DEPRECATED) {
                return;
        }

to line 161 in "/usr/share/webapps/phpldapadmin/lib/functions.php"

Re: [SOLVED] webapps broken with php 7.1

for the ZABBIX using PHP-FPM is a problem related with the ownership of the session folder.

inside:

/etc/opt/remi/php71/php-fpm.d/yuour_config.conf

this session:
php_value[session.save_path]    = /var/opt/remi/php71/lib/php/session

needs to have the same ownership as the pool that is running.
