Set this to false to turn debug output off or true to turn it on.
No value is returned.
This function was removed in PHP 8 and PECL OCI8 3.0.
This function is a no-op in PHP 5.6 and PECL OCI8 2.0. Use DTrace instead.
In PHP versions before 5.0.0 you must use ociinternaldebug instead. This name still can be used, it was left as alias of oci_internal_debug for downwards compatability. This, however, is deprecated and not recommended.
