Question

I’m working on a project in CodeIgniter 2 and now I’m stuck on the most basic of concepts.

Model:

Get an object array from my table which contains all rows that match a specific value for a field named foo. There can be one or more rows that match. In this example, two rows.

public function get_sample($foo)
{
    $query = $this->db->get_where('sample_db', array('foo' => $foo));

    return $query->result();
}

Controller:

Assign the results and make output available to view.

public function view($foo)
{
    $data['array'] = $this->sample_model->get_sample($foo);

    $this->load->view('view', $data);
}

View:

echo var_dump($array); // for testing

echo $array[1]->text

var_dump() of $array:

array(2) {
    [0]=> object(stdClass)#23 (4) {
        ["id"]=> string(1) "1"
        ["foo"]=> string(3) "bar"
        ["number"]=> string(4) "1234"
        ["text"]=> string(23) "This is content in 1234"
    }
    [1]=> object(stdClass)#24 (4) {
        ["id"]=> string(1) "2"
        ["foo"]=> string(3) "bar"
        ["number"]=> string(4) "9999"
        ["text"]=> string(23) "This is content in 9999"
    } 
} 

The rendered ouput of echo $array[1]->text; is: This is content in 9999

And I understand how all that is working: $array[1]->text is the content of the text field in the array object with the index of 1, my second object.

However, I have a field called number and I want to access the object with a certain number and get its corresponding text value.

Example: How can I retrieve the value of text where the number is 9999? I cannot use $array[1]->text since I can never be sure of the object’s position in the array. Something like $array['number' => '9999']->text, but I know that’s not right. Maybe I need to loop through the array looking for a match?

This looks so simple yet everything I’ve tried has failed and resulted in various PHP errors. I’ve been studying the PHP manual here and here, but cannot seem to find anything about what I’m looking to do, or maybe I’m just misapplying what I’m reading. Any guidance is appreciated.

In addition to an answer using best practices following the MVC model, I’m hoping for a link to the proper page in the documentation, as well as pointing out any errors in my wording/terminology above.

EDIT:

This answer contains the actual code I used to solve my problem. Although, Yagi’s answer was accepted because it put me in the right direction.

Answer 1

How about using this :

foreach ($array as $row) {
        if ($row->number == '9999') {
            echo $row->text;
        }
    }

Loop through the array, and find the number object value of 9999 and get the text
