array is not returning value for given key

Question

I am using the following PHP code...

$settings[] = get_app_settings();
echo $settings['weight_unit'];

but its throwing error 'undefined index'.

and when i do print_r($settings); it generates following...

Array ( [0] => Array ( [support_email] => [email protected] [support_phone] => 9812345678 [currency_symbol] => $ [weight_unit] => g. [catalogue_image_width] => 450 [catalogue_image_height] => 675 [single_product_image_width] => 500 [single_product_image_height] => 500 [product_image_width] => 200 [product_image_height] => 200 [tax_rate] => 1 [shipping_charges] => 0 ) )

Why is it not returning a value for $settings['weight_unit']; ?

Try $settings = get_app_settings(); - you probably want to assign the returned array directly and not to a new array element in $settings.
