Answer 1

In your example, the str_getcsv() function is completely useless. Your separator is a semicolon, and the str_getscv() function works with a comma separator by default. Change
to After the action, the elements will be divided as needed, and as a result, you can get the first element in this way: $csvArray[0][0] $csvArray[0][1] and so on.
