I have installed wamp, and pdo doesn't seem to work. I have tried enabling php_pdo_mysql from php exstensions, it appears checked but nothing changes in phpinfo , and the message "could not find driver" is still disabled. these are the 2 relevant lines from php info: PDO support enabled PDO drivers no value
also, this seemed a bit strange to me - Configure Command cscript /nologo configure.js "--enable-snapshot-build" "--without-dblib" "--without-pdo-dblib" "--without-pdo-mssql" "--with-pdo-oci=C:\php-sdk\php54dev\vc9\x64\deps\instantclient_10_2\sdk,shared" "--with-oci8=C:\php-sdk\php54dev\vc9\x64\deps\instantclient_10_2\sdk,shared" "--with-oci8-11g=C:\php-sdk\php54dev\vc9\x64\deps\instantclient_11_2\sdk,shared" "--disable-debug-pack" "--disable-static-analyze"
