explode Split a string by string arrayexplode stringseparator stringstring intlimit Returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by the string separator. If limit is set, the returned array will contain a maximum of limit elements with the last element containing the rest of string. If separator is an empty string (""), explode will return &false;. If separator contains a value that is not contained in string, then explode will return an array containing string. The limit parameter was added in PHP 4.0.1 Although implode can for historical reasons accept its parameters in either order, explode cannot. You must ensure that the separator argument comes before the string argument. See also preg_split, spliti, split, and implode.
