Previous Comments: ------------------------------------------------------------------------ [2017-06-28 13:04:35] shpr at libero dot it I can confirm the bug, in my case I have a lot of intermittent errors: Class Doctrine\\DBAL\\Driver\\PDOStatement contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (Doctrine\\DBAL\\Driver\\Statement::errorInfo, Doctrine\\DBAL\\Driver\\ResultStatement::closeCursor) in /opt/db/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOStatement.php on line 28 My environment Debian Jessie + Apache 2.4.10 + Php 7 with and without opcache. I dont'know how to reproduce the bug but I think is apache 2.4.x & PHP 7.x related. No problem with php 5.6 (never tried with other web servers). There are a lot of similar tickets in the web, for example: https://stackoverflow.com/questions/42503240/intermittent-php-abstract-class-error https://community.apachefriends.org/viewtopic.php?p=250966&sid=96ef58aaeb7fe142a7dcdfd506a8683f https://stackoverflow.com/questions/36088683/php-7-symfony-3-fatal-error-1-abstract-method-and-must-therefore-be-declared-a Can I help the php team in some way? How can I provide more logs? Thanks ------------------------------------------------------------------------ [2016-05-15 04:22:25] php-bugs at lists dot php dot net No feedback was provided.

It happens randomly on servers (10 of 400 servers production) Some letter a replaced by others, Class seems to be already declared.. etc Example of errors triggered after opcache_reset(): * Unknown column 'saken' in 'field list' => in this example t is replaced by s in the sql query. This can be really a big problem if in example on an update query a w of where is replaced by a ; and this will update whole table * PHP Fatal error: Cannot declare class ZZZZZ, because the name is already in use in /dir/dir/z.php on line 0 * PHP Fatal error: Class XXX contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (YYY::funczzz) in /dir/dir/x.php on line 20 * PHP Fatal error: Uncaught Error: Call to undefined method XXX::func1() in /dir/dir/x.php:218 It seems related to #71574 but it's still not corrected. php -v PHP 7.0.5-2+deb.sury.org~trusty+1 (cli) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies x@server:~# lsb_release --id Distributor ID: Ubuntu x@server:~# lsb_release -r Release: 14.04 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72112&edit=1
