Array (Delphi and PHP Cross Reference Guide)

By Mike Prestwood

Delphi versus PHP: A side by side comparison between Delphi and PHP.

Data Structures

Data structures allow you to store and work with data. Common data structures include arrays, associative arrays, etc.

Array

[Other Languages]

Languages Focus

A data structure in which individual values (called elements or items) may be located by reference to one or more integer index variables, the number of such indices being the number of dimensions in the array.

Arrays can start with an index value of 0 or 1, sometimes referred to as 0 based or 1 based.

Delphi: x=Array[0..3] of string;

Delphi supports both static and dynamic arrays as well as single and multi dimensional arrays.

Syntax Example:

var
  MyArray: array[0..3] of string;
  i: Integer;
begin
  MyArray[0] := 'Mike';
  MyArray[1] := 'Lisa';
  MyArray[2] := 'Felicia';
  MyArray[3] := 'Nathan';

  for i := 0 to High(MyArray) do
    ShowMessage(MyArray[i]);
end;

Delphi Array (x=Array[0..3] of string;) 1 certification question.
