PHP 8.2 is released 3 months ago, some updates to this version are comming.
Currently mantis does not even run. Warnings are one thing, but fatal errors or uncaught exceptions should be avoided.

patch added, to make mantis at least "work"

EDIT (dregad): for the record, the patch was added to 0031928

As stated, we are only supporting PHP up to 8.1 in the 2.25 branch, and we will not patch an upstream library for this. PHP 8.2 will be supported in version 2.26, when it is released (hopefully soon, as time allows).

In the meanwhile you're welcome to modify the source code of local instance, at your own risk of course.

Updating this issue since it seems that @dregad released 5.22.5 ADODB release - https://github.com/ADOdb/ADOdb/releases/tag/v5.22.5

Hello everyone.

I am using Fedora Rawhide with setup:

• Nginx proxy and SSL teremination,
• Apache web server,
• PHP 8.2.9RC1 with php-fpm
• MariaDB 10.5

It seems fairly complex and it kind of is, but it is also a popular solution with hosters.

First install page loads fine, but after typing database credentials I have this in Apache's error log:

Sun Jul 30 20:07:14.675852 2023] [proxy_fcgi:error] [pid 2132:tid 2132] [client 127.0.0.1:37698] AH01071: Got error 'PHP message: PHP Fatal error: Uncaught mysqli_sql_exception: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'schema()schema()' at line 5 in /var/www/fedoratestpinglocal/public_html/vendor/adodb/adodb-php/drivers/adodb-mysqli.inc.php:808\nStack trace:\n#0 /var/www/fedoratestpinglocal/public_html/vendor/adodb/adodb-php/drivers/adodb-mysqli.inc.php(808): mysqli_query()\n#1 /var/www/fedoratestpinglocal/public_html/vendor/adodb/adodb-php/adodb.inc.php(1282): ADODB_mysqli->_query()\n#2 /var/www/fedoratestpinglocal/public_html/vendor/adodb/adodb-php/adodb.inc.php(1260): ADOConnection->_Execute()\n#3 /var/www/fedoratestpinglocal/public_html/vendor/adodb/adodb-php/adodb.inc.php(2599): ADOConnection->Execute()\n#4 /var/www/fedoratestpinglocal/public_html/vendor/adodb/adodb-php/drivers/adodb-mysqli.inc.php(569): ADOConnection->MetaTables()\n#5 /var/www/fedoratestpinglocal/public_html/core/database_api.php(868): ADODB_mysqli->M...', referer: https://fedoratest.ping.local/

it has something to do with a file /var/www/fedoratestpinglocal/public_html/vendor/adodb/adodb-php/drivers/adodb-mysqli.inc.php and line 562:

$this->metaTablesSQL .= "schema()";

I think schema() is interpreted literally and not as a column name, as it should.

So yes, it is exacly like in 0031928 , which I just found.

PHP 8.2.9RC1 with php-fpm

@seem As you surely realize since you posted in this issue and also found 0031928, PHP 8.2 is not yet supported. Please try the same with PHP 8.1, it should work.

GuzzleHttp needs to be upgraded to 7.5 or later for PHP 8.2 support. See 0032807

It appears that the temporary workaround allowing REST API to run on PHP 8.1 (see 0032866) also fixes things for 8.2, so we should be able to resolve this without having to upgrade Slim framework to 4.x.
