拆分字符串

我的字符串看起來像下面：

哈佛大學的研究人員開發出無鉑固體氧化物燃料電池，這可能是可靠和移動技術足夠便宜。

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

從上面的字符串我只希望它的第一行，即：「哈佛大學的研究人員開發出無鉑固體氧化物燃料電池，這可能是可靠和移動技術足夠便宜。 「

休息一切都不是必需的。

要做到這一點，我已經試過：

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

但他們都不給我所需要的結果，這將是唯一的第一線，沒有和空格或全停後線。

有人可以幫我解決這個問題。

此外，如果有人可以編輯我的文本，因爲我無法粘貼我的示例字符串，因爲它實際上是。

Answer 1

在正則表達式點字符是一個特殊字符，你需要逃避它：

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

此外，拆分似乎過時，你應該使用使preg_split：http://us.php.net/manual/en/function.preg-split.php

Answer 2

喜歡的東西：

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

應該可以正常工作。要特別注意雙引號而不是單引號。

如果你正在做更多這種解析，你應該考慮一個HTML解析器，比如simplehtmldom。
