The php_pdo_firebird.dll is only an interface between PHP and the firebird engine. So you need firebird installed and also the php-pdo-firebird.dll needs to be able to find fbclient.dll

Try copying fbclient.dll into \wamp\bin\php\php7.1.10

If you also need access from Apache you may need to copy fbclient.dll into \wamp\bin\apache\apache{version}\bin as well and also amend the php.ini file that controls PHP under apache. Do that by using the wampmanager menus to edit the correct php.ini file like this

left click wampmanager icon -> PHP -> php.ini

For me, it got fixed after copying fbclient.dll file into the php installation folder. You have to download the Zip kit for manual/custom installs from the firebird website. You can find the file there. 64 bit version worked.

Download the 32 bits zip package from the firebird site. in the bin dir there is a fbclient.dll. Copy this dll to the php dir. (Not to the extension dir) and everything works.

copying fbclient to php bin did not work for me (and I spent a whole day trying to copy different versions of it).. instead copy it to apache/bin folder and it works (for me it was 64x version that worked)

The best thing to do is simply comment it out if you don't need it
