pass array from controller to view in codeigniter

Question

Model:

Grabs data from mySQL with the value: array['10','5','2'] and puts it in the session data

Controller:

Puts that session data into an array to pass to the view:

$fubar = array(
'ex1' => $this->session->userdata('ex1')
    );
$this->load->view('view', $fubar);

View:

echo $ex1;

The view will spit out the array: array['10','5','2'] How do I parse that array to get the individual values (10, 5, or 2)? For example, echo $ex1['1']; will spit out the first 1 characters: ar but I want it to return the value 5

I think perhaps I may not be storing the array properly in mySQL, but I'm not sure.

Please, put var_dump($fubar); before $this->load->view('view', $fubar); What does it display? — Max Kuznetsov

var_dump: array(4) { ["ex1"]=> string(21) "array['40','20','10']" ["ex2"]=> string(21) "array['80','40','20']" ["ex3"]=> bool(false) ["date"]=> string(10) "2012-09-08" } — user1616244

So, the arrays are not arrays at all, they're just strings. How do I parse those strings and save them as arrays? — user1616244

There is eval(<php code here>). But it's not safe. It's very strange that you save array as string. it's better to use serialize($your_array) and unserialize($your_serialized_array) functions or json_encode() and json_decode() functions. In conclusion: 1. Save in session: serialize($your_array); 2. Extract from session: unserialize($this->session->userdata('ex1')) — Max Kuznetsov

Why are your arrays being returned as strings? Post your model, or whatever is making this assignment. — Jordan Arsenault

$fubar['ex1'] = $this->session->userdata('ex1');
$this->load->view('view', $fubar);

Now Try

    $ex1[0];
    $ex1[1];

This is exactly the same thing than $fubar = array('ex1' => $this->session->userdata('ex1') );
