Why is the wrong value being read from CSV?

Question

PHP

How to understand it:
We take the number from the array: (read from CSV)

$NUMBER  =  $csvarr[0][0];                // В переменной $NUMBER  = 0;
$result = vagprice::find($NUMBER);
Возвращает <b>null</b>

$NUMBER = 0;
$result = vagprice::find($NUMBER);
Возвращает коллекцию

Answer 1

A classic BOM problem.
