继承我的剧本：http://ggcc.tv/JSON_Parsers/Music/getcities.php 继承我的json：http://www.godsgypsychristianchurch.net/music.json （请看两者）
问题 1.它打印出重复，
问：如何为每个城市打印一个链接（请参阅json＆amp; script）
应该只是
http://www.ggcc.tv/JSON_Parsers/Music/getalbums.php?churchname=Cleveland+OH
问：我该如何解决这个问题？
请记住，JSON有多个同一城市的对象，我只需要每个城市列出一次（不是多次）
我的PHP：
$churches = array();
$count = 1;
foreach ($json['rows'] as $row) {
++$count;
{
if (!in_array($row[doc]['church'], $churches))
$churches[] = $row[doc]['church'];
}
foreach ($churches as $church)
{
print '<a href="getalbums.php?churchname=' . urlencode($church) . '><br />' . htmlentities($church) . '</a>'; }
}
exit;
我的JSON：

答案 0 :(得分：1)
尝试将此作为您的PHP代码：
$churches = array();
$count = 1;
foreach ($json['rows'] as $row) {
++$count;
if (!in_array($row[doc]['church'], $churches)){
$churches[] = $row[doc]['church'];
}
}
foreach ($churches as $church){
print '<a href="getalbums.php?churchname=' . urlencode($church) . '><br />' . htmlentities($church) . '</a>'; }
}
exit;
在打开第二个foreach循环之前，你没有关闭它。你的缩进/牙箍结构非常混乱。如果你对此更加勤奋，你会发现像这样的小错误更容易
