我有以下代碼的Json分裂的print_r到FOREACH
$List2 = json_decode(file_get_contents("https://___URL____&format=json"),true);
以下作品完美
echo '<pre>';print_r($List2);echo '</pre>';
和例如產生
Array
(
[0] => Array
(
[uid] => 123456
[name] => John Williams
[pic_square] => http://nc4/565228_799523_q.jpg
[birthday_date] => 07/31/1987

我想運行一個foreach有所打印結果整潔明顯,所以我想以下幾點:
$data = $List2['data'] ;
foreach ($data as $nr => $friends){
echo $friends[name].' - ';
}
,但我得到
Warning: Invalid argument supplied for foreach()
我難倒這可能很簡單!
您應該簡單地使用'$ List2'代替'$ data'(其中還將是'null')。您正在打印一件東西,然後迭代另一件東西。結果令人驚訝嗎? – Jon 2012-04-24 14:42:36
