     oci_error() returns the last error found.  If
     the optional source is not
     provided, the last error encountered is returned. You can use
     connection or statement resources as value of parameter 
     source. If no error is
     found, oci_error() returns

     associative array. In this array, code
     consists the oracle error code and message
     the oracle error string.
    
As of PHP 4.3: 
      offset and sqltext will
      also be included in the return array to indicate the location
      of the error and the original SQL text which caused it.
