我收到了下面具有各种权限的JSON数组。如果您不知道publish_actions [status]值在哪个节点，如何检查它？（目前它在[3]中，但可能是任何其他数字）
JSON数组：
Array (
[data] => Array (
[0] => Array (
[permission] => installed
[status] => granted
)
[1] => Array (
[permission] => public_profile
[status] => granted
)
[2] => Array (
[permission] => manage_pages
[status] => granted
)
[3] => Array (
[permission] => publish_actions
[status] => granted
)
[4] => Array (
[permission] => user_groups
[status] => granted
)
)
)
使用json_decode，然后迭代数组：
$publish_actions_status = '';
$array=json_decode($json_string);
foreach($array['data'] as $node){
if($node['permission']=='publish_actions'){
$publish_actions_status = $node['status'];
break;
}
}
尝试
foreach($data as $k=>$v) {
if($v['permission']=='publish_actions'){
$newarr[]['permission'] = $v['permission'];
$newarr[]['status'] = $v['status']
}
}
print_r($newarr);
