reach 0 or less than
controller

//should i make static month to compare?

$update_item = assets::findOrFail($item->id);
$update_item->depriciation_cost = $item->depriciation - $item->depriciation_cost;
$update_item->update();
}

Answer 1

You can create a new column in the table to keep track of the last depreciation value updated like depreciation_updated_at (type: date) OR use created_at/updated_at column to get the last update month (if no other reason to update record).
Then simply use updated version of your code:
all_item=assets::all();
foreach($all_item as $item)
{
$month=Carbon::now()->format('m');
$depreciation_updated_at = createFromFormat('Y-m-d', $item->depreciation_updated_at); //or can use created_at/updated_at as said below
if ($depreciation_updated_at ->format('m') != $month) {
$update_item = assets::findOrFail($item->id);
$update_item->depriciation_cost = $item->depriciation - $item->depriciation_cost;
$update_item->update();
}
}
Hope it will do your task.
