用于解析字符串的PHP Regex帮助

string regex php

Ali · 技术社区 · 14 年前

我有如下字符串:

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

我想把这一段分成一个数组的基础上 <s> </s> 标记,因此我有以下数组作为结果:

[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);

但是这个只返回一个数组,其中包含在 <s></s>

我能找到的最接近的就是 preg_split() 取而代之的是:

$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));

得到这个结果:

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
)

除了生成一个额外的数组元素(索引 2 [city][State].</s> 和 <s>Josh's real estate company .

不过,添加一些代码来删除空白匹配项是很简单的,但我不确定您是否希望这样做。
