laravel check amount if in between the records - php

Question

I have a weight calculated, and a database table that contains the range of amounts, now I want to check if the calculated weight is between the ranges in my table.
I want to check the amount if it's between in one of the records in the table.
For example the calculated weight is 505kg it will find it on the table if it's between weight_from & weight_to, so it will return the 120 amount because 505kg is between 500 and 1000
Shipping Fee Table
+-----+---------------+--------------+-------------+
| id | weight_from | weight_to | amount |
+-----+---------------+--------------+-------------+
| 1 | 0.5 | 100 | 100 |
| 2 | 500 | 1000 | 120 |
| 3 | 1000 | 3000 | 180 |
+-----+---------------+--------------+-------------+
I found something like this, but it is not like what I'm trying to do, because it pass a number, and not getting the value of database table.
Code for reference only
$fee = Fee::whereBetween('column', [1, 150])->first();

Answer 1

whereBetween() is for finding values in a range within a single column. Since you are checking between two different columns, the checks needs to be explicit.
$weight = 505;
$fee = Fee::where('weight_from', '<=', $weight)
->where('weight_to', '>=', $weight)
->orderBy('weight_from')
->first();
if ($fee) {
// Do something with $fee->amount;
}
You shouldn't use <, the ranges should be inclusive. The reason for this, contrary to the other answer that states "use > for the upper-bound if the next range starts from the same value", is that the range may not always have the same upper-limit as the start-limit of your next batch (for example, the sample data provided has a range from 0.5 to 100, but none from 100-500). If it doesn't, then suddenly you're missing a value. Its better to use orderBy() to find the correct record. Combine that with first() and you only get one record.

Answer 2

I got it now, I want to share this simple yet helpful solution. This kind of logic is so confusing.
Code
$weight = 505;
$fee = Fee::where('weight_from', '<=', $weight)
->where('weight_to', '>', $weight)
->first();
if ($fee) {
// Do something with $fee->amount;
}
The weight_from should be less (or equal) to the calculated weight, and weight_to should be greater than the calculated weight
Also, use > for the upper-bound if the next range starts from the same value.
