How can the issue of storing the entire string in $array[0] be resolved when using preg_split() in PHP?

When using preg_split() in PHP, the issue of storing the entire string in $array[0] can be resolved by setting the third parameter of preg_split() to PREG_SPLIT_NO_EMPTY. This will prevent empty elements from being included in the resulting array. 

$string = "Hello, World!";
$array = preg_split("/,/", $string, -1, PREG_SPLIT_NO_EMPTY);
print_r($array);
