[英]last.fm api - random / shuffle foreach loop
我目前正在使用lat.fm api開發一個應用程序。
我有一個函數可以從last.fm組中獲取每周曲目列表。
目的是引入專輯插圖並制作“ gridview”模板。
下面的代碼執行此操作:
public function getWeeklyTrackChartGrid($methodVars) {
// Check for required variables
if ( !empty($methodVars['group']) ) {
$vars = array(
'method' => 'group.getweeklytrackchart',
'api_key' => $this->auth->apiKey
);
$vars = array_merge($vars, $methodVars);
if ( $call = $this->apiGetCall($vars) ) {
$i = 0;
//shuffle($call->weeklytrackchart->track);
$loopN = $call->weeklytrackchart->track;
foreach ($loopN as $track ) {
require 'config.php';
//if(++$i > $userLimit*2) break;
$albumArtS = $tracks['album']['image']['small'] = (string) $track->image[0];
$albumArtM = $tracks['album']['image']['small'] = (string) $track->image[1];
$albumArtL = $tracks['album']['image']['small'] = (string) $track->image[2];
$playCounts = $tracks[$i]['playcount'] = (string) $track->playcount;
?>
<?php if ($playCounts > 1) { ?>
<?php if ($albumArtL) { ?>
<img src="<?php echo $albumArtL; ?>" />
<?php } ?>
<?php } else { ?>
<?php if ($albumArtM) { ?>
<img src="<?php echo $albumArtM; ?>" />
<?php } ?>
<?php } ?>
<?php if ($albumArtwork == "yes") { ?>
<?php if ($albumArt) { ?>
<?php } }?>
<?php $i++;
}
return $tracks;
}
else {
return FALSE;
}
}
else {
// Give a 91 error if incorrect variables are used
$this->handleError(91, 'You must include a group variable in the call for this method');
return FALSE;
}
}
我想在foreach循環中使用php函數shuffle來隨機化音軌,而不是按last.fm給您的順序拉入它們。
如您所見,我沒有在上面評論隨機播放功能,當我添加此功能時,我收到以下警告:
Warning: shuffle() expects parameter 1 to be array, object given in
關於可能是什么問題的任何想法?
干杯,丹
$loopN = (array) $call->weeklytrackchart->track;
shuffle($loopN);
