It should be mentioned here, that oci_fetch_array() is insignificantly slower, than oci_fetch_row(), but much more handy.

인수

statement

A valid OCI statement identifier.

mode

An optional second parameter can be any combination of the following constants:

  • OCI_BOTH - return an array with both associative and numeric indices (the same as OCI_ASSOC + OCI_NUM). This is the default behavior.
  • OCI_ASSOC - return an associative array (as oci_fetch_assoc() works).
  • OCI_NUM - return a numeric array, (as oci_fetch_row() works).
  • OCI_RETURN_NULLS - create empty elements for the NULL fields.
  • OCI_RETURN_LOBS - return the value of a LOB of the descriptor.

Default mode is OCI_BOTH.

반환값

Returns an array with both associative and numeric indices, or FALSE if there are no more rows in the statement .

Note: 이 함수는 NULL 필드를 PHP NULL 값으로 설정합니다.

Note: Oracle returns all field names in uppercase and associative indices in the result array will be uppercased too.
