Hi everyone. I'm having trouble keeping the keys in the right places in an array of company names. I am sure I am falling victim to my own stupidity, so please forgive me if I am missing something obvious.
I've put it into a controller to hopefully make it easier for anyone to test.
Code:
<?php
class Test extends Controller {
function __construct()
{
parent::Controller();
}
function index($params="") {
$this->load->helper('form');
/**
* Let's imagine that this is an array of companies passed back
* from my model.
* This is going to be used in a dropdown box, and the ID is
* used as the value.
*/
$arr = array(
'3' => 'a company',
'5' => 'b company',
'4' => 'c company',
'2' => 'd company',
'1' => 'e company'
);
echo 'Here we can see that the array keeps the order specified above.<br />';
echo '<pre>',print_r($arr),'</pre>';
echo 'Now I merge this array with another array because I need an "Other" option<br />';
$arr = array_merge($arr, array('other' => 'Other'));
echo 'Here\'s the new array:<br />';
echo '<pre>',print_r($arr),'</pre>';
echo 'Hmmmm... What\'s happened to my array? The keys have been changed!';
}
}
For those who are happy to take my word for it, the first print_r($arr) displays:
Code:
Array
(
[3] => a company
[5] => b company
[4] => c company
[2] => d company
[1] => e company
)
After the array is merged with this one:
Code:
array('other' => 'Other');
...this is the result of the second print_r($arr):
Code:
Array
(
[0] => a company
[1] => b company
[2] => c company
[3] => d company
[4] => e company
[other] => Other
)
Is this PHP being strange, or is it just me being strange? Can anyone else confirm this? I am running "PHP 5.2.4-2ubuntu5.3 with Suhosin-Patch 0.9.6.2", straight from the Ubuntu repositories.
I do have a workaround, and that is to simply append some text to the beginning of the option values, but then I will have to strip it on the server. It's easily done, but is it really necessary?
