nachdem auslesen der Header zeilen habe ich mir den rest in einem weiteren feld des Arrays erstellt.
$rest=$buff32.fread($fdbf, filesize($dbfname));
$dbfhdrarr[]=$rest;
nun kann man mit etwas String bearbeitung und einer Foreach schleife jedes Feld ändern.
Filename ist der Name der Originalen dbf-Datei.
