Please use the following function

It is called in routing3.php if startedge-gid and end-edge-gid are equal.

```
if ($startEdge['gid']==$endEdge['gid']){
$abfrage_path_between_two_points="SELECT astext(intersection_on_line($result_besidegeometrie_begin_gid,'$point_on_line_begin','$point_on_line_ende')) as wkt,ST_length(schnittpunkt_auf_linie($result_besidegeometrie_begin_gid,'$point_on_line_begin','$point_on_line_ende')) as length";
//echo $abfrage_path_between_two_points;
$query7 = pg_query($con,$abfrage_path_between_two_points);
$result_path_between_two_points= pg_fetch_result($query7, 0, wkt);
$result_length_between_two_points= pg_fetch_result($query7, 0, length);
$searching_wkt_begin=$result_path_between_two_points;
$searching_wkt_ende=$result_path_between_two_points;
$length_begin=$result_length_between_two_points;
$length_ende=$result_length_between_two_points;
//echo "Die Strecke ".$result_path_between_two_points;
}
```
