Oci-php5.6 connection oracle, connection fails, how to configure?

My machine is win764-bit. I used php5.6 installed on xampps and configured the pdo extension, but I cannot see oci support in PDOdrivers of phpinfo, there is no problem in opening the pdo of sqlite and odbc, but opening the oci is not displayed, so the remote oracle cannot be connected. if newpdo is used, the oci_connection prompt method is not defined, the problem is that the driver cannot be found. isn't php5.6 able to connect to oracle? Almost all the items searched on Baidu are searched. the solution ociphporacle cannot be found.

If the new pdo method is used, the system prompts that the driver cannot be found.

The problem is that php5.6 does not support oracle connection?
