有这个帮助，它是专辑ID，我想只显示
特殊援助的图片，所以我写了这个：
for（$ i = 0; $ i< count（$ albums）; $ i ++）{
echo"< ; br>< b>"。$ albums [$ i] [''name'']。"< / b>< br>" ;;
$ album_aid = $专辑[$ i] [''援助''];
for（$ j = 0; $ j< count（$ photos）; $ j ++）{
$ photo_aid = $ photos [$ j] [''aid''];
if（$ photo_aid == $ album_aid）{
echo $ album_aid。" "。$ photo_aid;
echo"< a href = \""。$ photos [$ j] [''link'']。" \"> ;< img src = \""。$ photos [$ j]
['src_small'']。" \" ALT = \" Photo\"边界= \" 0\" />< / a>" ;;
}
}
echo"< br>" ;;
}
但是我一直在向我展示所有的照片，即使这些照片不同于b
。我查看了手册，但我不知道我在做什么
错了。有人可以帮帮我吗？
i = 0;
i< count（
相册）;

There is this aid, it is the album id, and I wanted to only show
pictures of a special aid, so I wrote this:
for($i=0;$i<count($albums);$i++){
echo "<br><b>".$albums[$i][''name'']."</b><br>";
$album_aid = $albums[$i][''aid''];
for($j=0;$j<count($photos);$j++){
$photo_aid = $photos[$j][''aid''];
if($photo_aid == $album_aid){
echo $album_aid." ".$photo_aid;
echo "<a href=\"".$photos[$j][''link'']."\"><img src=\"".$photos[$j]
[''src_small'']."\" alt=\"Photo\" border=\"0\" /></a>";
}
}
echo "<br>";
}
but i keeps showing me all of the pictures, even if the aids are
different. I looked in the manual, but I do not know what I am doing
wrong. Can someone please help me?
i=0;
i<count(
albums);
这篇关于比较两个字符串，我做错了什么？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
