hello all,

i have a variable that stores an array and i want to pass it to a new page using a querystring. any ideas on how to do that?

In general, that's not a good idea because there are limits to the amount of data you can transmit on the URL. Pass that (and the limit varies by OS and web server) and you may have problems.

If both scripts are on the same machine and under the same domain name, why not use session variables?

function parse_array_to_query_string ($array,$site)
{
  $st = $site;
  if (count($array) > 0)
  {
    $st .= "array0=" . $array[0];
  }
  foreach ($array as $key=>$value)
  {
    if ($key != 0)
    {
      $st .= "&array" . $key . "=" . $value;
    }
  }
  return $st;
}

You could also try a serialize plus a urlencode, followed by a urldecode and an unserialize.

That would save you the troubles of multidimensial arrays, and arrays which store objects.

But you're not going to get around the issues sleipnir brought up.

thanks for your replies everyone

it's strange because when i pass the array through the URL, the page that prints the array prints the correct amount of values stored in the array. but instead of priniting out what those values are, it only prints out:

Array
Array
Array

(it's correct that there are 3 array values stored in the array)

here's the code that's printing out the array which is passed through the url:

<?php

$EmailAddress2[]=$HTTP_GET_VARS["EmailAddress2"];

for($i=0;$i<count($EmailAddress2);$i++)
{
echo($EmailAddress2[$i]."<br />");
}

?>

Try "print_r( $yourarray );"
or "print serialize( $yourarray );"
