爆炸其他每一个字

Question

让我们说我有一个字符串:

$string = "This is my test case for an example."

如果我根据''得到一个爆炸而爆炸

Array('This','is','my','test','case','for','an','example.');

我想要的是每隔一个空间爆炸:

Array('This is','my test','case for','an example.').

字符串可能有一些奇数字,因此数组中的最后一项可能不包含两个单词.

有人知道怎么做吗？

Answer 1

我会查看结果,并在事后连接字符串.

Answer 2

$matches = array();
preg_match_all('/([A-Za-z0-9\.]+(?: [A-Za-z0-9\.]+)?)/',
       'This is my test case for an example.',$matches);

print_r($matches);

收益率:

Array
(
  [0] => Array
    (
        [0] => This is
        [1] => my test
        [2] => case for
        [3] => an example.
    )

  [1] => Array
    (
        [0] => This is
        [1] => my test
        [2] => case for
        [3] => an example.
    )
