can I write this line in HTML?

Answer 1

Use parse_str function

$str = "first=value&arr[]=foo+bar&arr[]=baz"; 
parse_str($str); 
echo $first;  

Answer 2

Use serialize and unserialize PHP function. This function giving you storable (string) version of array type. For more infomation about usage read http://php.net/manual/en/function.serialize.php and http://www.php.net/manual/en/function.unserialize.php

Answer 3

serialize() your array first and pass that through. Then call unserialize() on it. http://ie.php.net/serialize

Answer 4

You could use serialize and & serialize along side with urlencode e.g.

On Sending you can send them like these:

<?php
$array1 = Array(["key1"]=>"value1",["key2"]=>"value2");
$array2 = Array(["key1"]=>"value1",["key2"]=>"value2");
$data1="textdata";

$urlPortion= '&array1='.urlencode(serialize($array1)).
             '&array2='.urlencode(serialize($array2)).
             '&data1='.urlencode(serialize($data1));
//Full URL:
$fullUrl='http://localhost/?somevariable=somevalue'.$urlPortion
?>

On Receiving you can access them as:

<?php
$destArray1=unserialize($_GET['array1']);
$destArray2=unserialize($_GET['array2']);
$destData1=unserialize($_GET['data1']);
?>

And Voila, you can attach that url on ajax request or normal browser page.

Answer 5

Another option (even nice looking, I'd say):

<form method='POST'>
  <input type="hidden" name="idArray[]" value="1" />
  <input type="hidden" name="idArray[]" value="2" />
  <input type="hidden" name="idArray[]" value="3" />
  <input type="hidden" name="idArray[]" value="4" />
</form>

But of course it gets sent as POST. I wouldn'r recommend sending it with serialize since the output of that function can get pretty big and the length or URL is limited.

with GET:

<form method='GET'>
      <input type="hidden" name="idArray[]" value="1" />
      <input type="hidden" name="idArray[]" value="2" />
      <input type="hidden" name="idArray[]" value="3" />
      <input type="hidden" name="idArray[]" value="4" />
</form>

Answer 6

A session is a much safer and cleaner way to do this. Start your session with:

session_start();

Then add your serialized array as a session variable like this:

$_SESSION["venue"] = serialize($venue);

The simply call up the session variable when you need it.
