Split a comma-delimited string into an array?

Try explode:

$myString = "9,[email protected],8";
$myArray = explode(',', $myString);
print_r($myArray);

Output :

Array
(
    [0] => 9
    [1] => [email protected]
    [2] => 8
)

$string = '9,[email protected],8';
$array = explode(',', $string);

For more complicated situations, you may need to use preg_split.
