Как изменить логику парсинга доп. полей?

function xfieldsdataload($id) {
    
    if( $id == "" ) return;
    
    $xfieldsdata = explode( "||", $id );
    foreach ( $xfieldsdata as $xfielddata ) {
        list ( $xfielddataname, $xfielddatavalue ) = explode( "|", $xfielddata );
        $xfielddataname = str_replace( "|", "|", $xfielddataname );
        $xfielddataname = str_replace( "__NEWL__", "\r\n", $xfielddataname );
        $xfielddatavalue = str_replace( "|", "|", $xfielddatavalue );
        $xfielddatavalue = str_replace( "__NEWL__", "\r\n", $xfielddatavalue );
        $data[$xfielddataname] = $xfielddatavalue;
    }
    return $data;
}
