php_oci8.dll the library exists in the specified path.

tried to check the instant client oracle, sqlplus connects to the database.

read a lot of information, but I'm stumped how to move forward.

You configuration isn't picking up Instant Client. Where is it installed and have you set PATH? Maybe you need to move libraries to where the php dlls are?

Some really old notes I have are at https://blogs.oracle.com/opal/how-to-use-iis,-php-and-oracle

Also, for historic reasons OCI_CRED_EXT isn't supported on Windows, see https://github.com/php/php-src/blob/php-8.0.3/ext/oci8/oci8.c#L941-L948

What do you need OCI_CRED_EXT for?

(And why are you using such old Oracle Client libraries, - you should be able to drop in a newer set, since they keep compatibility)
