Need: php.ini lines for enabling the following:

• [x] The old MySQL Driver. - Extension=mysql
• [x] The new Mysqli Driver. - Extension=mysqli
• [x] The PostgreSQL driver. - Extension=pgsql
• [x] The old MsSQL driver. - Extension=mssql
• [x] The new MsSQL driver - Extension=sqlsrv.
• [x] The Oracle driver - Extension=oci8.

We can detect when BASE is running on windows and issue a more appropriate error message about enabling the necessary extension.

Expected Behavior: When $DBtype is set to mssql, transparently switch over to the sqlsrv driver. Current Behavior: BASE crashes.

Ok, @mesteele, it's in the devel branch, let us know how it works.

Also, any help with getting the php.ini lines to enable other DB drivers on Windows would be helpful.

As long as the extensions are added to the extension_dir and added as an extension= they will load.

extension_dir = "d:\winids\php\ext"

Do all the DB extensions in the extension dir follow the file naming convention of php_*.dll?

The idea is that the dll referenced in an error message for windows users will not necessarily point to the specific dll that will fix their issue, but that the suggested dll name is close enough to the solution that they can look in their extensions directory, see what they have, and hopefully figure it out from there.

For example, the sqlsrv dll can be named different things depending on PHP version built for, thread, safety, etc. It would be impossible to recommend a specific dll file to all end users, and be sure it worked.

[NathanGibbs3]

The only extension dll names I'm not sure about are the old MySQL & MsSQL drivers. They might be found on a PHP 5x installation. They were removed in PHP 7.

The official MS drivers for PHP 8.x are:

php_pdo_sqlsrv_80_nts_x64.dll php_pdo_sqlsrv_80_nts_x86.dll php_pdo_sqlsrv_80_ts_x64.dll php_pdo_sqlsrv_80_ts_x86.dll php_pdo_sqlsrv_81_nts_x64.dll php_pdo_sqlsrv_81_nts_x86.dll php_pdo_sqlsrv_81_ts_x64.dll php_pdo_sqlsrv_81_ts_x86.dll php_pdo_sqlsrv_82_nts_x64.dll php_pdo_sqlsrv_82_nts_x86.dll php_pdo_sqlsrv_82_ts_x64.dll php_pdo_sqlsrv_82_ts_x86.dll php_sqlsrv_80_nts_x64.dll php_sqlsrv_80_nts_x86.dll php_sqlsrv_80_ts_x64.dll php_sqlsrv_80_ts_x86.dll php_sqlsrv_81_nts_x64.dll php_sqlsrv_81_nts_x86.dll php_sqlsrv_81_ts_x64.dll php_sqlsrv_81_ts_x86.dll php_sqlsrv_82_nts_x64.dll php_sqlsrv_82_nts_x86.dll php_sqlsrv_82_ts_x64.dll php_sqlsrv_82_ts_x86.dll

PHP.ini omits the php_ and the .dll - So the extension for Windows x64 PHP 8.2 and Apache would be:

extension=sqlsrv_82_ts_x64

[NathanGibbs3]

Thanks, that helped me refine the error message a bit more. It won't point end users to the exact dll they need for their installation, but it will get them close enough to figure it out from there.

Better than compile time options for building PHP from source, which most of the time doesn't apply to the situation, especially on windows.
