我有一个脚本,其中列出了一些 Twitch.tv 流并显示它们是离线还是在线。我正在尝试将它集成到我的一个页面中,但我遇到了几个未定义的偏移错误。
这是脚本:
<html>
<head>
<title>Streamlist</title>
</head>
<body>
<?php
$members = array("painuser","ZombieGrub","Nathanias","Youbetterknowme","ncl_tv");
// This variable becomes one long url with the channel names stringed up behind it
// This url then fetches a json file from twitch with all the selected channels information
$userGrab = "http://api.justin.tv/api/stream/list.json?channel=";
$userGrab .= implode(",", $members);
//I use this array to compare with the members array. All users in this arrat are substracted from the members array and hence are //"offline"
$checkedOnline = array ();
foreach($members as $i =>$value){
$userGrab .= ",";
$userGrab .= $value;
}
unset($value);
//grabs the channel data from twitch.tv streams
$json_file = file_get_contents($userGrab, 0, null, null);
$json_array = json_decode($json_file, true);
//get's member names from stream url's and checks for online members
$channels = array();
for ($i = 0; $i < count($members); $i++) {
$title = $json_array[$i]['channel']['channel_url'];
$array = explode('/', $title);
$member = end($array);
$viewer = $json_array[$i] ['stream_count'];
onlinecheck($member, $viewer);
$checkedOnline[] = signin($member);
}
unset($value);
unset($i);
//checks if player streams are online
function onlinecheck($online, $viewers)
{
//If the variable online is not equal to null, there is a good change this person is currently streaming
if ($online != null)
{
echo '<a href="http://www.twitch.tv/'.$online.'"> <strong>'.$online.'</strong></a>';
echo '  <img src="/images/online.png"><strong> Status:</strong> Online! </br>';
echo '<img src="/images/viewers.png"><strong>Viewers:</strong>  ' .$viewers.'</br>';
}
}
//This funcion add's online channel names to the checked online array
function signin($person){
if($person != null){
return $person;
}
else{
return null;
}
}
?>
<hr>
<?php
//This part list all the people currently offline. Here the array with online users is compared with the total users.
//online users are then removed from the total users array.
foreach ($members as $i => $value1) {
foreach($checkedOnline as $ii => $value2){
if($value1 == $value2){
unset($members[$i]);
}
}
}
//print a nice list with people that can't currently be bothered with streaming their games
foreach ($members as $ii => $value2) {
echo '<a href="http://www.twitch.tv/'.$online.'"> <strong>'.$online.'</strong></a>';
echo '  <img src="/images/online.png"><strong> Status:</strong> Online! </br>';
echo '<img src="/images/viewers.png"><strong>Viewers:</strong>  ' .$viewers.'</br>';
echo '<a href="http://www.twitch.tv/'.$value.'"> <strong>'.$value.'</strong></a>';
echo ' <img src="/images/offline.png"> <strong> Status :</strong> Offline! </br>';
}
?>
</body>
</html>
在此之后,我使用此代码来显示流:
//This part list all the people currently offline. Here the array with online users is compared with the total users.
//online users are then removed from the total users array.
foreach ($members as $i => $value1) {
foreach($checkedOnline as $ii => $value2){
if($value1 == $value2){
unset($members[$i]);
}
}
}
//print a nice list with people that can't currently be bothered with streaming their games
foreach ($members as $i => $value) {
echo '<a href="http://www.twitch.tv/'.$value.'"> <strong>'.$value.'</strong></a>';
echo ' <img src="/images/offline.png"> <strong> Status :</strong> Offline! </br>';
}
现在,错误。我得到这个:

有人可以帮忙吗?有没有办法解决这个问题?我不擅长 PHP,我不知道该怎么做。
