PHP: POST data of hidden fields error

Question

I'm trying to pass on some hidden fields in a form from one page to another:

<form action=\"secondPage.php\" method=\"post\">
   <input name=\"from\" type=\"hidden\" value=\"$fday/$fmonth/$fyear\">
   <input name=\"to\" type=\"hidden\" value=\"$tday/$tmonth/$tyear\">
   <input type=\"submit\">
</form>

secondPage.php contains:

<?php
   $fdate = $_POST("from");
   $tdate = $_POST("to");
   echo "$fdate --- $tdate";
?>

I get this error on when I click submit and am redirected to secondPage.php:

Fatal error: Array callback has to contain indices 0 and 1 in C:\xampp\htdocs\blah\secondPage.php on line 2

Killing Curves. Arrays in PHP are accessed with [] not () $_POST("to"); should be $_POST["to"]; — Robot Boy

PHP uses square brackets rather than parentheses for accessing arrays:

<?php

    $fdate = $_POST["from"];
    $tdate = $_POST["to"];
    echo "$fdate --- $tdate";

?>
