oci_fetch_array Returns the next row from a query as an associative or numeric array &reftitle.description; arrayoci_fetch_array resourcestatement intmode Returns an array containing the next result-set row of a query. Each array entry corresponds to a column of the row. This function is typically called in a loop until it returns &false;, indicating no more rows exist. If statement corresponds to a PL/SQL block returning Oracle Database 12c Implicit Result Sets, then rows from all sets are consecutively fetched. If statement is returned by oci_get_implicit_resultset, then only the subset of rows for one child query are returned. &oci.datatypes; &reftitle.parameters; statement &oci.arg.statement.id; Can also be a statement identifier returned by oci_get_implicit_resultset. mode An optional second parameter can be any combination of the following constants: Constant Description OCI_BOTH Returns an array with both associative and numeric indices. This is the same as OCI_ASSOC + OCI_NUM and is the default behavior. OCI_ASSOC Returns an associative array. OCI_NUM Returns a numeric array. OCI_RETURN_NULLS Creates elements for &null; fields. The element values will be a PHP &null;. OCI_RETURN_LOBS Returns the contents of LOBs instead of the LOB descriptors. The default mode is OCI_BOTH. Use the addition operator "+" to specify more than one mode at a time. &reftitle.returnvalues; Returns an array with associative and/or numeric indices. If there are no more rows in the statement then &false; is returned. By default, LOB columns are returned as LOB descriptors. DATE columns are returned as strings formatted to the current date format. The default format can be changed with Oracle environment variables such as NLS_LANG or by a previously executed ALTER SESSION SET NLS_DATE_FORMAT command. Oracle's default, non-case sensitive column names will have uppercase associative indices in the result array. Case-sensitive column names will have array indices using the exact column case. Use var_dump on the result array to verify the appropriate case to use for each query. The table name is not included in the array index. If your query contains two different columns with the same name, use OCI_NUM or add a column alias to the query to ensure name uniqueness, see example #7. Otherwise only one column will be returned via PHP. &reftitle.examples; \n"; echo $row[1] . " and " . $row['DEPARTMENT_NAME'] . " are the same
