PHP Array Help

[AJLX]

Hey guys,

 

I have a php array that looks like this:

Array
(
    [opportunity_items] => Array
        (
            [0] => Array
                (
                    [id] => 2783
                    [opportunity_id] => 92
                    [item_id] => 
                    [item_type] => 
                    [opportunity_item_type] => 0
                    [opportunity_item_type_name] => Group
                    [name] => Strobes
                    [transaction_type] => 
                    [transaction_type_name] => 
                    [accessory_inclusion_type] => 
                    [accessory_inclusion_type_name] => 
                    [accessory_mode] => 

The array goes on for ages, but I have only shown the bits I need. I want to create a new array that just contains the [id] key.

 

I can get the first value by doing this:

echo $array["opportunity_items"]["0"]["id"];

But I somehow I need to loop through this to get all of the rest of the values.

 

Thanks,

 

Andy

Try using array_column on $array["opportunity_items"].

[AJLX]

Thanks for your reply. I'm still on PHP 5.4, so this hasn't been implimented yet, and upgrading isn't an option.

Then try writing the equivalent code. It uses a foreach loop and... well, that's it really. A single foreach loop.

[AJLX]

I finally got there!

foreach ($obj as $key) {
	
	foreach ($key as $id) {
		
		print_r($id['id']);
	}
}

If you worked for me and my requirement was

 

I want to create a new array that just contains the [id] key.

 

and you came up with that as a solution, then you wouldn't be getting paid.

[AJLX]

Out of interest what would your solution be? This is for my own personal use, you'll be pleased to know I don't do this as a day job. Any opportunity to learn new things is appreciated...

print_r() is a debugging tool for viewing an array, it does not produce an array. This will give you the desired array.

$id_array = [];     // initialize array
foreach ($data['opportunity_items'] as $k => $item) {
    $id_array[$k] = $item['id'];
}

[AJLX]

Ah yes! The code I used above with print_r was just to prove that the result was correct. The code I used to actually build the array looked like this:

$assets = array();

foreach ($obj as $key) {
	
	foreach ($key as $id) {
		
		$assets[] = ($id['id']);		
	}
}

Thanks
