Explode ($delimiter, $string [, $limit])

The parameters are described as follows:

$delimiter: the delimited character used to split the string

$string: the string to be split

$limit: optional parameter, which can be empty to specify the number of array elements to be returned

If $limit is not empty and is positive, the returned array contains at most $limit elements, and the last element contains the rest of $string

If $limit is not empty and is negative, all elements except the last $limit element are returned

If $limit is 0, it will be treated as 1

If $limit is empty, all array elements are returned.
