在PHP中拆分字符串的問題

Question

我的字符串如下所示：

哈佛大學的研究人員開發了無鉑固體氧化物燃料電池，這種燃料電池對於移動技術而言可能是可靠且便宜的。

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

從上面的字符串我只想要它的第一行，即：“哈佛大學的研究人員開發出無鉑的固體氧化物燃料電池，這對於移動技術來說可靠且便宜。”

休息全部不是必需的。

為此，我嘗試過：

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

但是它們都不給我所需的結果，它只是第一行，句號后面沒有和空格或行。

有人可以幫我解決這個問題。

另外，如果有人可以編輯我的文本，因為我無法粘貼我的示例字符串，實際上是這樣。

Answer 1

在正則表達式中，點字符是特殊字符，您需要對其進行轉義：

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

另外，拆分似乎已被棄用，您應該使用preg_split： http : //us.php.net/manual/en/function.preg-split.php

Answer 2

就像是：

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

應該工作正常。 要特別注意雙引號而不是單引號。

如果您要進行更多此類解析，則應考慮使用HTML解析器，例如simplehtmldom 。
