Question

我有以下文字，我希望在每个段落之间添加<br>标记。并删除所有换行符。我将如何在PHP中执行此操作？感谢。

所以这个 -

This is some text
for which I would
like to remove 
the line breaks.

And I would also 
like to place
a b>  tag after 
every paragraph.

Here is one more
paragraph.

会成为这个 -

This is some text for which I would like to remove the line breaks.<br/> And I would also like to place a br tag after every paragraph. <br> Here is one more paragraph.

注意：忽略任何字母的突出显示。

Answer 1

好吧，你似乎考虑了一个段落分隔符，一个空行。所以最简单的解决方案就是这样：

$text  = str_replace( "\r", "", $text ); // this removes the unwanted \r
$lines = explode( "\n", $text ); // split text into lines.
$textResult = "";
foreach( $lines AS $line )
{
   if( trim( $line ) == "" ) $textResult .= "<br />";
   $textResult .= " " . $line;
}

我认为这可以解决您的问题。 $textResult会得到你的结果

Answer 2

这也应该有效:(虽然过于简单）

$string = str_replace("\n\n", "<br />", $string);
$string = str_replace("\n", "", $string);

经过测试。

Answer 3

要么我缺少某些内容，要么没有人能够提供最简单的解决方案 - 内置函数nl2br：

echo nl2br($string);

只记得，如果你使用纯字符串（不是变量）作为nl2br的参数，你必须使用双引号或你的控制字符，如\n或{{1不会被扩展。

Answer 4

echo str_replace(array("\n\n", "\n"), array("<br/>", " "), $subject);

上面将带有<br/>标记的双重换行符和任何剩余的单个换行符替换为空格（以避免最初仅由换行符分隔的单词相互竞争）。

你是否需要迎合CRLF（windows）风格的换行符;这会稍微（虽然不是很大）改变方法。

Answer 5

这适合我

$string = ereg_replace( "\n", "<br/>", $string);

删除换行符并在PHP中添加BR标记
