Topic: MariaDB fix - needs re-run
The commit for allowing MariaDB uses an inline array reference on explode that is not accepted in PHP 5.3.1 and needs to be fixed as in the comment in it by replacing line 27 in includes/system_tests.inc:
$test['result'] = $test['test']>='4.1' || explode('-', $test['test'])[1] == 'MariaDB';with:
if(!($test['result'] = ($test['test']>='4.1'))) {
$db_str = explode('-', $test['test']);
$test['result'] = ($db_str[1] == 'MariaDB');
}
