Tworząc rozbudowany formularz każdemu polu tego formularza należy nadać nazwę. Można to zrobić wykorzystując różne nazwy zmienych różnicujących o które pole chodzi, ale można także użyć do tego celu zmienną tablicową. Jest to uproszczony sposób, gdyż ułatwia odwołanie się do zawartości różnych pól w formularzu.

Przykład:

Kod: html4strict

<form action="index.php" method="post">
  <input name=pole[] type="text" /><br />
  <input name=pole[] type="text" /><br />
  <input name=pole[] type="text" /><br />
  <input value="wyślij" type="submit" />
</form>

Kod: php

<?php
// odbranie informacji ze zmiennej tablicowej $pole[]
echo $_POST["pole"][0]."<br />";
echo $_POST["pole"][1]."<br />";
echo $_POST["pole"][2]."<br />";

// odbranie informacji ze zmiennej tablicowej $pole[] z wykorzystaniem pętli
for($i=0;$i<count($_POST["pole"]);$i++) {
  echo $_POST["pole"][$i]."<br />";
}
?>
 

W powyższym przykładzie odwołanie się do zmiennych nazywających pola formularza odbywa się przez pobranie ich ze zmiennej tablicowej $pole[] poprzez podanie indexu tablicy - 0,1,2… Wykorzystując fakt, że indexy numerowane są kolejnymi cyframi, można zastosować pętlę pobierającą z tablicy dane.
