Question

大家好我试图使用foreach格式化基于this picasa script的html输出，这样：

<? foreach($albums as $photo) {?>  
<span><img src="<? echo $photo[1]; ?>" border=0></a><p><?=$photo[0]; ?></p></span> 
    <?  } ?>

输出结果为：

<span><img src="foto1.jpg" border=0></a><p>This is pict 1 Album 1</p></span>
<span><img src="foto2.jpg" border=0></a><p>This is pict 2 Album 1</p></span>
<span><img src="foto3.jpg" border=0></a><p>This is pict 3 Album 1</p></span>
<span><img src="foto4.jpg" border=0></a><p>This is pict 4 Album 2</p></span>

但我需要这个：

<div>
<h1>Album 1</h1>
<span><img src="foto1.jpg" border=0></a><p>This is pict 1 Album 1</p></span>
    <span><img src="foto2.jpg" border=0></a><p>This is pict 2 Album 1</p></span>
    <span><img src="foto3.jpg" border=0></a><p>This is pict 3 Album 1</p></span>
</div>
<div>
<h1>Album 2</h1>
    <span><img src="foto4.jpg" border=0></a><p>This is pict 4 Album 2</p></span> 
 </div>

这个想法是将我的picasa帐户中的所有相册带到里面，例如：

album 1 has:
foto1.jpg
foto2.jpg
foto3.jpg

album 2 has:
foto4.jpg

所以...这就是我希望有人可以帮助我，更好地理解我真正糟糕的英语：）

Answer 1

如果您希望将输出拆分为“相册”，您需要知道如何根据照片属于哪个相册来分割照片数组。你是如何填充$照片的？每张“专辑”中只有3张照片吗？

Answer 2

在这里，你的功课已经完成了

<div>
<h1>Album 1</h1>
<? foreach($albums as $photo) {?>  
<span><img src="<? echo $photo[1]; ?>" border=0></a><p><?=$photo[0]; ?></p></span> 
<?  } exit;?>
</div>
<div>
<h1>Album 2</h1>
    <span><img src="foto4.jpg" border=0></a><p>This is pict 4 Album 2</p></span> 
</div>

另请注意其他答案。拆分哪个“foto”进入哪个专辑需要更多信息，这只是一个html标记的例子，所以你可以理解php如何适合混合

使用Picasa PHP FOREACH的Html / Markup格式
