我需要从[stream]的类别和值中获取[description]的值。我只显示[0]数组到[1]，有超过20个。
使用for循环来获取所有数据。
<body>
<?php
$json_string = 'http://api.dirble.com/v2/stations?
token=123';
$jsondata = file_get_contents($json_string);
$obj = json_decode($jsondata,true);
?>
<p id="demo"></p>
<script>
var i, j, x = "";
for (i in obj.categories) {
x += "<h2>" + obj.categories[i].description + "</h2>";
}
document.getElementById("demo").innerHTML = x;
</script>
</body>
答案 0 :(得分：0)
你应该做这样的事情，
foreach(YOUR_MAIN_ARRAY as $value) {
foreach($value["categories"] as $tmpValue) {
foreach($tmpValue as $description){
echo $description["description"];
}
}
foreach($value["streams"] as $tmpValue) {
foreach($tmpValue as $stream){
echo $stream["stream"];
}
}
}
它包含语法错误，因为我没有测试过，但逻辑很清楚。
