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.
Замечание: The limit parameter was added in PHP 4.0.1
Замечание: 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.
