explode -- Split a string by string


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 .

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.

Note: The limit parameter was added in PHP 4.0.1

Example 1. explode() examples

// Example 1
$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
$pieces[0]; // piece1
echo $pieces[1]; // piece2

// Example 2
$data = "foo:*:1023:1000::/home/foo:/bin/sh";
$user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data);
$user; // foo
echo $pass; // *
