Question

im using codeigntier framework im trying to solve a problem to do with retrieving information from a database for example:

model.php:

public function read(){
   $query = $this->db->get('table');
   return $query->result();
}

controller.php:

  public function doSomething () {
       $exampleArray['name'] = "Bob's Database";
       $getModel = $this->load->model('model','getData');
       $modelData = $this->getData->read();
       // i want to assign the the $modelData to a array element like so
       $exampleArray['modelData'] = $modelData // here's where im stuck :(
}

thanks for your help!!
p.s. this is not an error, its just a question 🙂

Answer 1

If you want to be able to access $exampleArray outside of that method, you’ll have to do one of two things:

a) set it as a class variable

class MyClass {
    public $exampleArray;
    .
    .
    . 
}

then refer to it using

$this->exampleArray['index']

or b) pass it by reference into your doSomething() function:

public function doSomething(&$exampleArray) { ... }

The php manual has a section on variable scope that should help you better understand this.
