string Required. The string to split.
limit Optional. Specifies the maximum number of array elements returned.


Explanation
This function returns an array composed of strings, each element of which is a substring separated by separator as a boundary point .

separator parameter cannot be an empty string. If separator is the empty string (""), explode() returns FALSE. If separator contains a value that is not found in string, explode() returns an array containing a single element from string.

If the limit parameter is set, the returned array contains at most limit elements, and the last element will contain the remainder of the string.

If the limit parameter is a negative number, all elements except the last -limit elements are returned. This feature isnewin PHP 5.1.0.

Note: Due to historical reasons, althoughimplode() can receive two parameter orders, explode() cannot. You must ensure that the separator parameter comes before the string parameter.
