分别打印从php中的api获取的多维数组
提问于 2018-06-16 23:08:10
我想把这个单独打印出来。如何将其转换为数组，以便打印此值
[
{"id":19,"name":"The Rainbow Room","desc":"Guppy X Delta Network Party","category":"Party","photos":
[{"id":21,"url":"http:\/\/delta.development.s3.ap-southeast-1.amazonaws.com\/system\/App\/Models\/EventPhoto\/photos\/000\/000\/021\/medium\/Rainbow%20328x%20716-02%20%282%29.png"}]
},{"id":22,"name":"Kashish 2018 ","desc":"Together with Pride","category":"Film Festival","photos":[]

为了打印每个单独的项目，您需要将三维数组转换为二维数组：
$mainarray = json_decode($jsondata, true);
$formatted =[];
foreach($mainarray as $key=>$value){
if(is_array($value)){
foreach($value as $k=>$v){
if(is_array($v)){
foreach($v as $sk=>$sv){
$formatted[$key]['photoid'] = $sv['id'];
$formatted[$key]['photourl'] = $sv['url'];
}
}else{
$formatted[$key][$k] = $v;
}
}
}
}
print_r($formatted);输出：
Array
(
[0] => Array
(
[id] => 19
[name] => The Rainbow Room
[desc] => Guppy X Delta Network Party
[category] => Party
[photoid] => 21
[photourl] => http://delta.development.s3.ap-southeast-1.amazonaws.com/system/App/Models/EventPhoto/photos/000/000/021/medium/Rainbow%20328x%20716-02%20%282%29.png
)
[1] => Array
(
[id] => 22
[name] => Kashish 2018
[desc] => Together with Pride
[category] => Film Festival
)
[2] => Array
(
[id] => 21
[name] => Cosplay Night
[desc] => Guppy X Delta Network Party
[category] => Party
[photoid] => 20
[photourl] => http://delta.development.s3.ap-southeast-1.amazonaws.com/system/App/Models/EventPhoto/photos/000/000/020/medium/Cosplay%20328x%20716-01%20%282%29.png
)
)要打印数据，请执行以下操作：
foreach($formatted as $data=>$row){
echo $row['name']."\n";
}输出：
The Rainbow Room
Kashish 2018
Cosplay Night要打印名字：
echo $formatted[0]['name'];//for second change zero(0) to [1]页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
