codeigniter - Generate multi-dimensional array in Controller, how to call it in view

Question

Generally we use one-dimensional arrays, for example:
$data['regions'] = $this->index_model->get_region();
Then use $regions directly in the view to make data calls.
But what if I want to generate a multidimensional array, for example:
$data[1]['streets'] = $this->index_model->get_street(1,1);
$data[2]['streets'] = $this->index_model->get_street(2,1);
In this way, how to call it in the view, thank you everyone~

Answer 1

Place the contents of a multidimensional array into an element of the array passed to the $this->load->view() method, like this:

$data['streets'][1]['streets'] = $this->index_model->get_street(1,1);
$data['streets'][2]['streets'] = $this->index_model->get_street(2,1);

Then pass the $data array to the $data数组传递给$this->load->view() method, like this:

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

After that you can call it like this in the view:

<?php echo $streets[1]['streets']; ?>
<?php echo $streets[2]['streets']; ?>
