Field separation in array

Question

I have a string consisting of (enclosed quotes):

"campo","outrocampo","maisumcampo"

I need to separate these fields, without the quotes, into an array.

What I’m doing is a

 $string = str_replace('"', NULL, $string)

and then a

 $array = explode(',', $string);

However, if any of the fields in the original string will contain a comma inside the quotes, I think I will have problems. How to avoid this?

Answer 1

How about using a function that was created specifically to read CSV?

$array = str_getcsv($string);
