type

// How to use it:
// Und hier ein Beispiel zur Verwendung:
procedure TForm1.Button1Click(Sender: TObject);
var
S: string;
A: TStrArray;
AnzTokens, i: Integer;
begin
S := 'Ein=Text=durch=Geleichzeichen=getrennt';
AnzTokens := Explode(A, '=', S);
for i := 0 to AnzTokens -1 do
Memo1.Lines.Add(A[i]);
end;

* These 2 functions are from the programming language PHP, unite certainly well-known.
* Now one can use it also in Delphi:)
* Diese 2 Funktionen sind aus der Programmiersprache PHP, einigen bestimmt bekannt.
* Nun kann man sie auch in Delphi verwenden :)
