폭발 기능 지침

// 示例 1
$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2
// 示例 2
$data = "foo:*:1023:1000::/home/foo:/bin/sh";
list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data);
echo $user; // foo
echo $pass; // *
?>

例 2. limit 参数例子

$str = 'one|two|three|four';
// 正数的 limit
print_r(explode('|', $str, 2));
// 负数的 limit（自 PHP 5.1 起）
print_r(explode('|', $str, -1));
?>

上例将输出： Array ( [0] => one [1] => two|three|four ) Array ( [0] => one [1] => two [2] => three )
