Code Examples

oci_field_type( resource$statement, string|int$column ): string|int|false

statement: A valid OCI statement identifier.
column: Can be the field's index (1-based) or name.

In PHP versions before 5.0.0 you must use ocicolumntype instead. This name still can be used, it was left as alias of oci_field_type for downwards compatability. This, however, is deprecated and not recommended.
