explode
(PHP 4, PHP 5)
explode — Split a string by string
Descrierea
Returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by the string delimiter .
Parametri
- delimiter
-
The boundary string.
- string
-
The input string.
- limit
-
If limit is set, the returned array will contain a maximum of limit elements with the last element containing the rest of string .
If the limit parameter is negative, all components except the last -limit are returned.
Although implode() can, for historical reasons, accept its parameters in either order, explode() cannot. You must ensure that the delimiter argument comes before the string argument.
Valorile întroarse
If delimiter is an empty string (""), explode() will return FALSE. If delimiter contains a value that is not contained in string , then explode() will return an array containing string .
