Question

我有以下输出为json。我怎样才能回显它的DND_status？以下是代码。

JSON OUTPUT：

Array ( [0] => Array ( [mobilenumber] => 9809657248 [DND_status] => on [activation_date] => 09-10-2014 17:23 [current_preference] => 0 [preference_history] => Array ( [0] => Array ( [preference_date] => 20-08-2012 [preference] => 0 [status] => Active ) [1] => Array ( [preference_date] => 13-08-2012 [preference] => 0 [status] => Active ) [2] => Array ( [preference_date] => 17-07-2012 [preference] => 0 [status] => Active ) [3] => Array ( [preference_date] => 16-07-2012 [preference] => 0 [status] => Active ) [4] => Array ( [preference_date] => 09-07-2012 [preference] => 0 [status] => Active ) ) ) )

PHP代码：

<?php
$opts = array(
  'http'=>array(
    'method'=>"GET",
    'header'=>"X-Mashape-Key: xd7lpM6y3ImshZOdNfobRDPhiBU4p100Q2JjsnaAlOTxVWrkwZ"               
  )
);

$context = stream_context_create($opts);
    $res = file_get_contents('https://dndcheck.p.mashape.com/index.php?mobilenos=9809657248', false, $context);
    $res = (json_decode($res, true));
    print_r ($res);          // print the above json
    echo $res['DND_status']; //not working
    echo $res->DND_status;   //not working
?>

Answer 1

直接阅读数组：

<?php 

$opts = array(
  'http'=>array(
    'method'=>"GET",
    'header'=>"X-Mashape-Key: xd7lpM6y3ImshZOdNfobRDPhiBU4p100Q2JjsnaAlOTxVWrkwZ"               
  )
);

$context = stream_context_create($opts);
$res = file_get_contents('https://dndcheck.p.mashape.com/index.php?mobilenos=9809657248', false, $context);
$res = (json_decode($res, true));
print_r ($res);          // print the above json

echo $res[0]['DND_status']; // what you need by reading in array

?>

或使用foreach循环：

<?php 

$opts = array(
  'http'=>array(
    'method'=>"GET",
    'header'=>"X-Mashape-Key: xd7lpM6y3ImshZOdNfobRDPhiBU4p100Q2JjsnaAlOTxVWrkwZ"               
  )
);

$context = stream_context_create($opts);
$res = file_get_contents('https://dndcheck.p.mashape.com/index.php?mobilenos=9809657248', false, $context);
$res = (json_decode($res, true));
print_r ($res);          // print the above json


foreach ($res as $key => $value) {
    echo $value['DND_status']; // what you need by foreach method
}
?>

Answer 2

试试这应该有效：

echo $res[0]['DND_status'];

Answer 3

如评论中所述，使用foreach循环

foreach ($opts as $opt) {
    foreach ($opt as $op) {
        echo $op['method'];
        echo $op['header'];
    }
}
