php - 在PHP中带有两个定界符的preg_split

如何在preg_split中合并两个定界符？例如:

$str = "this is a test , and more";
$array = preg_split('/( |,)/', $str, -1, PREG_SPLIT_DELIM_CAPTURE);
print_r($array);

将产生一个数组

Array
(
    [0] => this
    [1] =>
    [2] => is
    [3] =>
    [4] => a
    [5] =>
    [6] => test
    [7] =>
    [8] =>
    [9] => ,
    [10] =>
    [11] =>
    [12] => and
    [13] =>
    [14] => more
)

但我想得到

Array
(
    [0] => this
    [1] =>
    [2] => is
    [3] =>
    [4] => a
    [5] =>
    [6] => test
    [7] => ,
    [8] => and
    [9] =>
    [10] => more
)

实际上，当两个定界符是邻居时，我想合并数组元素。换句话说，如果下一部分是第二个定界符，则忽略第一个定界符。

最佳答案

尝试使用字符类:/[ ,]+/+是一个量词，表示“1或更多”
