If statement within an array declaration …is that possible? [duplicate]

Answer 1

Even if you could do that it is much more readable to add the conditional after or before the array.

Answer 2

As far as I know, no. But why would you even do that, that is a bad idea. You should only be setting variables in an array, do you logic outside.

$data = array(
    'product_option_value_id' => $product_option_value['product_option_value_id'],
    'name'                    => $product_option_value_description_query->row['name'],
    'price'                   => $product_option_value['price'],
    'prefix'                  => $product_option_value['prefix']
);

if (isset($product_option_value_description_query->row['smallimage'])) {
    $data['small_image'] = $product_option_value_description_query->row['smallimage'];
}

$product_option_value_data[] = $data;

Answer 3

No, You can do it inline or externaly:

$product_option_value_data[] = array(
    'product_option_value_id' => $product_option_value['product_option_value_id'],
    'smallimage'                  => @$product_option_value_description_query->row['smallimage'],
    'name'                    => $product_option_value_description_query->row['name'],
    'price'                   => $product_option_value['price'],
    'prefix'                  => $product_option_value['prefix']
);

Or if smallimage cannot be empty:

$product_option_value_data[] = array(
    'product_option_value_id' => $product_option_value['product_option_value_id'],
    'name'                    => $product_option_value_description_query->row['name'],
    'price'                   => $product_option_value['price'],
    'prefix'                  => $product_option_value['prefix']
);

if (isset($product_option_value_description_query->row['smallimage'])) {
    $product_option_value_data['smallimage'] = $product_option_value_description_query->row['smallimage'];
}

Answer 4

You can define the array and then add some items:

$des = array(...);
if(...)
   $des["..."] = "...";

Answer 5

Maybe this one?

$array = array(
    'key1' => 'value1',
    'key2' => 'value2',
);

if (isset(...)) {
    $array['key3'] = 'value3';
}

$multiarray[] = $array;

Answer 6

In this case only possible option is to use following syntax:

'smallimage' => (isset($product_option_value_description_query->row['smallimage']) 
  ? isset($product_option_value_description_query->row['smallimage'])
    : NULL)

Though this has side effect, if your condition fails you will have "smallimage" key with value of NULL
