这样的事情怎么样(其他人建议使用explode
- 所以我建议另一个解决方案):
$str = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.";
if (preg_match('/^([^\.]*)/', $str, $matches)) {
echo $matches[1] . '.';
}
正则表达式将:
^
[^\.]
[^\.]*
并且,如果你想在输出的末尾有一个.
且.
与正则表达式不匹配,那么在使用正则表达式找到的内容时,你必须将其添加回来
