Question

我正在处理一个php文件，该文件从mysql表生成一个kml文件，然后我可以使用谷歌地图。我有文件启动并运行但是，我在文本中遇到一些问题，这些问题应该出现在点击标记后弹出的气泡中。首先，只有文本的第一部分出现[b_name]，其次，我想格式化泡泡中的文本，但我的html标签只显示为文本。

我从中提取信息的表是一个视图，使用以下sql创建：

create view totalbaeir as 
select syslur.sysla, hreppar.hreppur, baeir.b_name, baeir.lat, baeir.lng, baertyper.stjarna
from hreppar, syslur, baeir, baertyper
where (syslur.syslaid = hreppar.syslaid)
AND (baeir.hrepparid = hreppar.hrepparid) order by baeir.b_name;

这给了我一个包含以下字段的视图：

sysla     (equivalent to f.x. a state)
hreppur   (equivalent to f.x. a county)
b_name    (farm name)
lat       (latitude)
lng       (longitude)
stjarna   (farm-type, gives the value used to generate a style in the kml file).

这里可以看到php / kml文件生成的标记示例：http://hafdal.dk/index.php/da/kirker/kegnaes-kirke/9-test

这里可以看到php / kml输出：http://www.hafdal.dk/kml/phpsql_rakeltest1.php

如果您查看下面的php文件，您可以看到气泡中的文本是使用以下代码生成的：

$descText = htmlentities("<b>".$row['b_name']."</b>".$row['hreppur']);

但是如果你看一下气泡，只显示变量b_name，格式化不起作用。

我有什么想法可以解决这个问题吗？

这是我的php文件：
