PHP 7.4 support for phpBB 3.3

Post by Heo32 »

Please refer here for details and the reasoning why it should be supported: ... -released/
Due to changes in the MySQL authentication method, PHP versions prior to 7.4 are unable to authenticate to a MySQL 8.0 or newer server (our tests show the problem actually began with MySQL 8.0.11). This relates to a PHP bug There is a workaround, that is to set your user account to use the current-style password hash method, mysql_native_password. This unfortunate lack of coordination has caused the incompatibility to affect all PHP applications, not just phpMyAdmin. For more details, you can see our bug tracker item at
In summary, if PHP 7.4 is not supported on phpBB 3.3 in combination with phpMyAdmin (any version) being used, then people will not be able to also use MySQl 8.0.x, which offers better performance and security than MySQL 5.7.x and below, unless mysql_native_password is used.

By chance, is this the planned implementation of PHP 7.4 for phpBB 3.3 and 4.0, Marc? If so, please lock and disregard this suggestion.

I went to your board and looked for an hour or so, but did not see the women without underwear.

3.3.x should be PHP 7.4 ready, you can help testing it out installing the Beta2 which has been released today.

Not really an idea. If you find that phpBB 3.3.x does not support PHP 7.4, please report it to the tracker.
