php - How to store data inside session array in given format? -

- 

category name   list = rm 20   list b = rm 50  category name   list = rm 40  category name   list = rm 80   list b = rm 40   list c = rm 25

i tried

$_session['info']=array('category'=>$category,'list'=>$list,'rate'=>$rate);

but doesn't display format wanted. can please?`

edit:

i think didn't elaborate clearly.

the values item category, list , rate come user input.

so store them in variables this:

php

$category[]=$_post['category'];<br/> $list[]=$_post['list']; $rate[]=$_post['rate'];

storing in session array this:

$_session['info']]=array('level'=>$level,'subject'=>$subject2,'rate'=>$rate2);`

html

<input type="checkbox" name="category['category name']" id="category" class=category" value="1">  <input type="checkbox" name="list['category name']" id="list" value="'list id'">  <input type="textbox" name="rate['list name']" class="rate" value="" id="'list name'">

try following:

$_session['info'] = array(     'category name' => array(         'list a' => 'rm 20', // don't forget "," if you're adding additional item.         'list b' => 'rm 50'     ),      'category name' => array(         'list a' => 'rm 40'     )     // etc.. );
