php adding elements to array not working

Question

I'm inserting elements dinamically in array, elements are inserted OK, but only the last one

I think that push_array will solve the problem, and I try

array_push($rowsItemAddit, $rowsItemAddit["item"]["acId"], $precio_row_addit->acId);

But I get error

Notice: Undefined index: item

My code working for the last element is

foreach($precios_row_addit as $precio_row_addit){
    $rowsItemAddit["item"]["acId"] = $precio_row_addit->acId;
    $rowsItemAddit["item"]["acValues"]  = array ( 'acValue' => $precio_row_addit->acValue );                    
    }

Any ideas to get the complete array?

The final structure should be:

[additionalColumnValues] => Array
    (
        [item] => Array
            (
                [acId] => 0
                [acValues] => Array
                    (
                        [acValue] => 10
                    )

            )
        [item] => Array
            (
                [acId] => 1
                [acValues] => Array
                    (
                        [acValue] => 10
                    )

            )               
        [item] => Array
            (
                [acId] => etc.
                [acValues] => Array
                    (
                        [acValue] => 10
                    )

            )
    )

        )

)

TIA

You need to code it like this

foreach ($precios_row_addit as $precio_row_addit) {
    $rowsItemAddit[] = array('item' => array(
            'acId' => $precio_row_addit->acId,
            'acValues' => array('acValue' => $precio_row_addit->acValue)
        ));
}

This would not match the structure he wanted

You always try to overwrite the same array elements. It can't have multiple keys named "item"

Try something like this, where the item index is an numeric index rather than "item":

foreach($precios_row_addit as $precio_row_addit){
    $rowsItemAddit[]["acId"] = $precio_row_addit->acId;
    $rowsItemAddit[]["acValues"] = array ( 'acValue' => $precio_row_addit->acValue );                    
}

Not exactly what I wanted. Here my results

Jam Over a year ago

Array([0] => Array ( [acId] => 0 ) [1] => Array ( [acValues] => Array ( [acValue] => 10 ) ) [2] => Array ( [acId] => 1 ) [3] => Array ( [acValues] => Array ( [acValue] => K-CostCenter ) ) )

The problem with $rowsItemAddit[] is that now there are 2 different nodes,

Hmm.. yeah. But now you know, that the structure you wanted to have can not work with arrays in php, right? An array key is a unique identifier which can not appear twice or more

Thanks all for your answers, finally I've got it guided with your thoughts. This is the final code, I use a temp array $wrk = array(); $wrk ["acId"] = $precio_row_addit->acId; $wrk ["acValues"]["acValue"] = $precio_row_addit->acValue; $rowsItemAddit["item"] = $wrk;
