拆分字符串

我的字符串看起来像下面：

哈佛大学的研究人员开发出无铂固体氧化物燃料电池，这可能是可靠和移动技术足够便宜。

<br clear="both" style="clear: both;"/> 
<br clear="both" style="clear: both;"/>

从上面的字符串我只希望它的第一行，即：“哈佛大学的研究人员开发出无铂固体氧化物燃料电池，这可能是可靠和移动技术足够便宜。 “

休息一切都不是必需的。

要做到这一点，我已经试过：

$description = split(' \n', $string); 
$description = split('<', $string);  
$description = split('. ', $string); 

但他们都不给我所需要的结果，这将是唯一的第一线，没有和空格或全停后线。

有人可以帮我解决这个问题。

此外，如果有人可以编辑我的文本，因为我无法粘贴我的示例字符串，因为它实际上是。

Answer 1

在正则表达式点字符是一个特殊字符，你需要逃避它：

$description = split('\.', $string); 

此外，拆分似乎过时，你应该使用使preg_split：http://us.php.net/manual/en/function.preg-split.php

Answer 2

喜欢的东西：

$description = current(explode("\n", $string)); 

应该可以正常工作。要特别注意双引号而不是单引号。

如果你正在做更多这种解析，你应该考虑一个HTML解析器，比如simplehtmldom。
