I simply want to know how to access array elements retrieved from a database. I have the following code to get the names of each item in my database.
$plat_options = $this->db->get('tblplatform_options')->select('name')->result();
How do I go about accessing the name from the array $plat_options? Typically I would do $plat_options[0] for the first element in C#, how is this done in php/codeigniter?
In PHP/Codeigniter, can be done in the same way:
$plat_options[0] //if you have this element, usually is better to check if exists.
You can retrieve all the elements with foreach($plat_options as $option){...}
You can cast to object: https://www.kathirvel.com/php-convert-or-cast-array-to-object-object-to-array/
Or use a Codeigniter Helper (assuming you are using CI3): http://www.codeigniter.com/user_guide/helpers/array_helper.html
I recomend to know which is your array format and retrieve that way (if you don't know, you can do a: var_dump($plat_options) ) to know if is an associative array.
You can use the result_array() function:
$data = $plat_options->result_array();
echo($data[0]['name']);
or:
$data = array_shift($q->result_array());
echo($data['name']);
I extracted this last part from: Codeigniter $this->db->get(), how do I return values for a specific row? that you could check too.
If you don't know a lof of CI, the best you can do is do a simple tutorial to understand how the data + ActiveRecord works.
Hope it helps!
print_r($plat_options);that will show you the array in a pretty readable and understandable format
