内容图文

我有一个如下字符串：

Are you looking for a quality real estate company? 

<s>Josh's real estate firm specializes in helping people find homes from          
[city][State].</s>

<s>Josh's real estate company is a boutique real estate firm serving clients 
locally.</s> 

In [city][state] I am sure you know how difficult it is
to find a great home, but we work closely with you to give you exactly 
what you need

我想将此段基于< s>拆分为一个数组< / s>标签,因此我得到以下数组：

[0] Are you looking for a quality real estate company?
[1] Josh's real estate firm 
    specializes in helping people find homes from [city][State].
[2] Josh's real estate company is a boutique real estate firm serving clients 
    locally.
[3] In [city][state] I am sure you know how difficult it is
    to find a great home, but we work closely with you to give you exactly 
    what you need

这是我当前正在使用的正则表达式：

$matches = array();
preg_match_all(":<s>(.*?)</s>:is", $string, $matches);
$result = $matches[1];
print_r($result);

但这仅返回一个数组,其中包含在< s>之间找到的文本. < / s>标签,它将忽略在这些标签之前和之后找到的文本. (在上面的示例中,它将仅返回数组元素1和2.

有任何想法吗？

解决方法:

我能得到的最接近的是使用preg_split()：

$string = <<< STR
Are you looking for a quality real estate company? <s>Josh's real estate firm 
specializes in helping people find homes from [city][State].</s>
<s>Josh's real estate company is a boutique real estate firm serving clients 
locally.</s> In [city][state] I am sure you know how difficult it is
to find a great home, but we work closely with you to give you exactly 
what you need
STR;

print_r(preg_split(':</?s>:is', $string));

并得到以下输出：

Array
(
    [0] => Are you looking for a quality real estate company? 
    [1] => Josh's real estate firm 
specializes in helping people find homes from [city][State].
    [2] => 

    [3] => Josh's real estate company is a boutique real estate firm serving clients 
locally.
    [4] =>  In [city][state] I am sure you know how difficult it is
to find a great home, but we work closely with you to give you exactly 
what you need
)

除非产生额外的数组元素(索引2),否则在片段[city] [State]之间存在换行符.和< s> Josh的房地产公司.

虽然添加一些代码以删除空格匹配是微不足道的,但是我不确定您是否希望这样做.
