pushing objects into existing array with php

Question

In JS I would do something like this:

var arr = [];  
arr.push({ 
   sku : foo, 
   quantity: bar 
});

How do I do this with PHP? When I try to do this I'm getting a parsing error.

For example with PHP:

$someArray = array(); // or maybe someArray = []; ???
$someArray = array_push(
  'sku' => $sku,
  'quantity' => $quantity
);

Is this correct?

Thank you!

thx for link, I checked this, but the prob is not with adding 1 value to the existing array. I'm having a trouble with the key/value pairs. — jremi

$someArray = array_push([ 'sku' => $sku, 'quantity' => $quantity ]); perhaps? — Mark Baker

it looks like you are trying to pass an array into an array so you can array_merge() maybe. — Dhaval Chheda

check this: array_push

you could do:

$array = [];
array_push($array, "item");

or

$array = [];
$item = "hi";
$array['key'] = $item;

or you could use

$array = [];
array_merge($array, ["abc" => 1]);

also your js code is equivilant to

$array = [];
array_push($array, ['item' => 'value', 'item1' => 'value1']);


// is equivalent to 
var arr = [];  
arr.push({ 
   sku : foo, 
   quantity: bar 
});

No need for an array_push function. See ex:

$arr = [];
$arr['sku'] = $sku;
$arr['quantity'] = $quantity;

when handling key -> value pairs.

Edit (multidimensional one):

for($a=0; $a < $total ; $a++)
{    
  $arr[$a]['sku'] = $sku;
  $arr[$a]['quantity']  = $quantity;
}

I am looping over data and need to push them into the master array. The method you have described here will overwrite. I need to keep pushing each new sku/quantity into the master array.

Then I can think of two easy options. You can either insert the array to the master array after each iteration, or you can keep the data in a multi-dimensional array. Check my edit.

This was accomplished by the following:

array_push($someArray, ["sku" => $sku, "quantity" => $quantity]);
