从上面的字符串我只想要它的第一行，即：“哈佛大学的研究人员开发出无铂的固体氧化物燃料电池，这对于移动技术来说可靠且便宜。”

休息全部不是必需的。

为此，我尝试过：

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

但它们都没有给我所需的结果，这只是第一行，没有空格或直线后的行。

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。

此致 Zeeshan

Answer 1

在正则表达式中，点字符是一个特殊字符，您需要将其转义：

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

另外，split似乎已被弃用，你应该使用preg_split：http://us.php.net/manual/en/function.preg-split.php

Answer 2

类似的东西：

$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。

如果您正在进行更多此类解析，则应考虑使用HTML解析器，例如simplehtmldom。
