How can I split a delimited string into an array in PHP?

I need to split my string input into an array at the commas.

How can I go about accomplishing this?

Answer 1

What if you want your parts to contain commas? Well, quote them. And then what about the quotes? Well, double them up. In other words:

part1,"part2,with a comma and a quote "" in it",part3

PHP provides the https://php.net/str_getcsv function to parse a string as if it were a line in a CSV file which can be used with the above line instead of explode:

print_r(str_getcsv('part1,"part2,with a comma and a quote "" in it",part3'));
Array
(
    [0] => part1
    [1] => part2,with a comma and a quote " in it
    [2] => part3
)
