# explode

(PHP 3, PHP 4 )

explode -- Split a string by string

## Description

array explode ( string separator, string string [, int limit])

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`.

> Note: The `limit` parameter was added in PHP 4.0.1

Example 1. explode() examples

    $pizza = "piece1 piece2 piece3 piece4 piece5 piece6";
    $pieces = explode(" ", $pizza);

    $data = "foo:*:1023:1000::/home/foo:/bin/sh";
    list($user,$pass,$uid,$gid,$gecos,$home,$shell) = explode(":",$data);

> Note: 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.
