Question

我有以下代码：

$string = "zero Or one OR two or three";
print_r(explode("or", $string));

现在，这导致：

Array ( [0] => zero Or one OR two [1] => three )

但我想忽略分隔符的情况，因此它适用于Or，OR，...我的结果是：

Array ( [0] => zero [1] => one [2] => two [3] => three )

我该怎么做？

使用preg_split()

CREATE TRIGGER trMyTable_Update ON parent AFTER UPDATE 

 AS

    IF not exists (select 1 from deleted)

       return

    if exists (select 1 from deleted where SEARCHID IS NOT NULL)
      AND (UPDATE(SEARCHID) OR UPDATE(SEARCHID))  -- attempt to change existing values

     begin

         raiserror('You can not change values in SEARCHID or ANYOTHER once they were saved!',16,1)

         rollback

   end

输出：

$string = "zero Or one OR two or three";
$keywords = preg_split("/or/i", $string);
echo '<pre>';print_r($keywords);echo '</pre>';

如何爆炸一个字符串忽略分隔符的情况？
