Description:
------------
The documentation should add a note that the function or oracle change/resets the oracle error flag at each call when a resource statement passed in. If you call it two times with same statement resource parameter the second call get no error.

Test script:
---------------
<?php $ociUser = 'system';
$ociPass = 'mudar123';
$hostAddress = '192.168.1.43';
$ociConnString = '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST='.$hostAddress.')(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)))';

$ociDbHandler = oci_connect( $ociUser, $ociPass, $ociConnString );

if ( !$ociDbHandler )
{ #call oci_error without args to check for connection errors
	 var_dump( __LINE__, oci_error() );
	 exit();
}

//sample from website
$stmt = @oci_parse( $ociDbHandler, "select ' from dual");  // note mismatched quote
if ( !$stmt )
{
  var_dump( __LINE__, oci_error( $ociDbHandler ) ); // For oci_parse errors pass the connection handle
  var_dump( __LINE__, oci_error( $ociDbHandler ) );
}
$stmt = 'select TABLE_NAME from ALL_TAB_COLUMNS, ALL_TAB_COLUMNS clone where ALL_TAB_COLUMNS.TABLE_NAME = clone.TABLE_NAME';
$stmt = @oci_parse( $ociDbHandler, $stmt );
$flag = @oci_execute( $stmt, OCI_DEFAULT );  // note duplicated column name
if ( !$flag )
{ #here the error message is not displayed on second call
  var_dump( __LINE__, oci_error(), oci_error( $ociDbHandler ), oci_error( $stmt ), $stmt ); // For oci_parse errors pass the connection handle
  var_dump( __LINE__, oci_error(), oci_error( $ociDbHandler ), oci_error( $stmt ), $stmt ); // For oci_parse errors pass the connection handle
  exit;
}
exit( 'end' );  ?>

Expected result:
----------------
Expected that each call on same resource reported the same errors.

Actual result:
--------------
int(27) bool(false) bool(false) array(4) { ["code"]=> int(918) ["message"]=> string(37) "ORA-00918: column ambiguously defined" ["offset"]=> int(7) ["sqltext"]=> string(113) "select TABLE_NAME from ALL_TAB_COLUMNS, ALL_TAB_COLUMNS clone where ALL_TAB_COLUMNS.TABLE_NAME = clone.TABLE_NAME" } resource(2) of type (oci8 statement)

int(28) bool(false) bool(false) bool(false) resource(2) of type (oci8 statement)
