我想拆分一个字符串，其中任何字符都是空格或标点符号（不包括撇号）。以下正则表达式按预期工作。
/[^a-z']/i
像"我会"和"没有"这样的词被接受，这很好。
问题在于像'ere和'im这样的词。我想删除开头的撇号，并带有im和ere这两个词。
如果可能的话，理想情况下，我想在正则表达式模式中停止/删除它。
提前谢谢。
试试这个
$str = "Words like I'll and Didn't are accepted, which is great.
The problem is with words like 'ere and 'im";
print_r(preg_split("/'?[^a-z']+'?/i", $str));
//Array ( [0] => Words [1] => like [2] => I'll [3] => and [4] => Didn't ...
// [16] => ere [17] => and [18] => im )
