(PHP 5, PECL OCI8 >= 1.1.0)
oci_password_change — Changes password of Oracle's user
Changes password for user with username.
Returns TRUE on success or FALSE on failure.
Note: The second oci_password_change() syntax is available since version 1.1.
In PHP versions before 5.0.0 you must use ocipasswordchange() instead. This name still can be used, it was left as alias of oci_password_change() for downwards compatability. This, however, is deprecated and not recommended.
