如何在标签上爆炸，这样我就能得到数组中的值?

I tried this

我试着这

   $myString =  "Overall Queen Poster <br /> Queen Poster Headboard:<br /> Queen Poster <br /> Queen Footboard  <br /> Queen Poster Rails: 62.28"W x 84.02"D x 18.07"H - 37lbs";

But not getting correct result.

但是没有得到正确的结果。

That's because   != \n.

那是因为
!= \n。

You can use regex to split it, to make sure that you get all the BR tags ( ,  ,  ,  ,   etc.)

您可以使用regex对其进行拆分，以确保获得所有的BR标记( ，
，
，
，
等)。

Code:

代码:

<?php
    $myString = 'Overall Queen Poster <br /> Queen Poster Headboard:<br /> Queen Poster <br /> Queen Footboard  <br /> Queen Poster Rails: 62.28"W x 84.02"D x 18.07"H - 37lbs.';

    $myArray = preg_split('/<br[^>]*>/i', $myString);

    print_r($myArray);
?>

Outputs:

输出:

Array
(
    [0] => Overall Queen Poster 
    [1] =>  Queen Poster Headboard:
    [2] =>  Queen Poster 
    [3] =>  Queen Footboard  
    [4] =>  Queen Poster Rails: 62.28"W x 84.02"D x 18.07"H - 37lbs.
)

演示

Limitations:

限制:

Will split on any HTML tags that start with br. Meaning that if you made your own tag, such as <breadcrumb>, this would mistakenly be seen as a line break.

将在任何以br开头的HTML标记上拆分。也就是说，如果您创建了自己的标记，比如，这将被错误地视为换行符。

Alternatives:

选择:

explode(' ', $myString) if you're sure that your tags will always be exactly  
如果您确信您的标记将始终为
，那么就会爆炸('
'， $myString)
preg_split('/<br\s*/?>/i', $myString) if you have tags such as <breadcrumb> and don't have any attributes in any   tag.
preg_split(' / 这样的标签，并且在任何
标签中都没有任何属性，那么就使用>/i'， my$ myString)。

Extra notes:

额外的注释:

If you don't want white-space in your matches, you can change your regex to /<br[^>]*>\s*/i which will also match any white-space characters after the match. Alternatively, you can run it through ltrim with $myArray = array_map('ltrim', $myArray);.

如果你不想要白色空间在你的比赛,你可以改变你的正则表达式/ < br[^ >]* > \ s * /我也将匹配任何空白字符匹配后。或者，您可以使用$myArray = array_map('ltrim'， $myArray)在ltrim中运行它;

#2

The input is provided as a html encoded string so the line breaks are encoded as   so why don't you just take   as the separator instead of \n ?

输入以html编码字符串形式提供，因此换行符被编码为
，所以为什么不把
作为分隔符而不是\n呢?
