Description
bool 
oci_password_change ( resource connection, string username, string old_password, string new_password )
resource 
oci_password_change ( string dbname, string username, string old_password, string new_password )
     Changes password for user with username.
     Parameters old_password and
     new_password should indicate old and new passwords
     respectively.
    
Note: 
      The second oci_password_change() syntax is available
      since version 1.1.
     
     Returns TRUE on success or FALSE on failure.
    
Note: 
      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.
