MY Array Helper

Contains functions to be used with arrays. Extends CI's array helpers.

This helper is loaded using the following code:

$this->load->helper('array');

The following functions are available:

array_sorter(array, index, ['order'], [nat_sort], [case_sensitive])

Array sorter that will sort on an array key and allows for asc/desc order. It returns an array. 

$my_arr[0] = array('first_name' => 'Darth', 'last_name' => 'Vader');
$my_arr[1] = array('first_name' => 'Luke', 'last_name' => 'Skywalker');
$my_arr[2] = array('first_name' => 'Han', 'last_name' => 'Solo');

$new_arr = array_sorter($my_arr, 'first_name', 'asc');

echo $new_arr[0]['first_name'].' '.$new_arr[0]['last_name']; // Luke Skywalker

object_sorter(data, key, [order])

Array sorter that will sort an array of objects based on an objects property and allows for asc/desc order. Default order is 'asc'. Does not return anything but changes the original object by reference.

$obj1 = new stdClass();
$obj1->first_name = 'Darth';
$obj1->last_name = 'Vader';

$obj2 = new stdClass();
$obj2->first_name = 'Luke';
$obj2->last_name = 'Skywalker';

$obj3 = new stdClass();
$obj2->first_name = 'Han';
$obj2->last_name = 'Solo';

$my_obj[0] = $obj1;
$my_obj[1] = $obj2;
$my_obj[2] = $obj3;

object_sorter($my_obj, 'first_name', 'asc');

echo $my_obj[0]->first_name.' '.$my_obj[0]->last_name; // Luke Skywalker

options_list(data, [value], [label])

Creates a key/value array based on an original array. Can be used in conjunction with the Form library class (e.g. $this->form->select('characters, option_list($options)))

$my_obj[0] = array('id' => 1, 'first_name' => 'Darth', 'last_name' => 'Vader');
$my_obj[1] = array('id' => 2, 'first_name' => 'Luke', 'last_name' => 'Skywalker');
$my_obj[2] = array('id' => 3, 'first_name' => 'Han', 'last_name' => 'Solo');

$options = options_list($my_arr, 'id', 'last_name');
echo $options[1]; // Vader
echo $options[2]; // Skywalker
echo $options[3]; // Solo

parse_string_to_array(str)

Parses a string in the format of key1="val1" key2="val2" into an array.

$str = 'first_name="Darth" last_name="Vader"';
$options = parse_string_to_array($str);
echo $options['first_name']; // Darth
echo $options['last_name']; // Vader
