我正试图从dailymotion获取视频网址。 我获得了JSON结果,并使用在线工具进行了有效测试,但是当我使用js_decode& print_r它显示警告,如
<?php
$content = file_get_contents("http://www.dailymotion.com/embed/video/x49oyt5");
$content = explode(',"qualities":', $content);
$json = explode(',"reporting":', $content[1]);
$json = $json[0];
$mycontent = file_get_contents($json);
$response = json_decode($mycontent, true);
print_r($response);
?>
我想从JSON获得视频质量和视频网址。

你在实际上已经是JSON的地方使用了file_get_contents。
更新的代码,经过测试;)
<?php
$content = file_get_contents("http://www.dailymotion.com/embed/video/x49oyt5");
$content = explode(',"qualities":', $content);
$json = explode(',"reporting":', $content[1]);
$json = $json[0];
$videos = json_decode($json,true);
//Cycle through the 1080 videos and print the video urls
foreach($videos[1080] as $video){
printf("Video type:%s URL:%s\n", $video['type'], $video['url']);
}
//Cycle through the 720 videos and print the video urls
foreach($videos[720] as $video){
printf("Video type:%s URL:%s\n", $video['type'], $video['url']);
}
?>

使用array_keys($array)
,您可以从数组中获取所有键,它将返回带有键的数组。
<?php
$content = file_get_contents("http://www.dailymotion.com/embed/video/x49oyt5");
$content = explode(',"qualities":', $content);
$json = explode(',"reporting":', $content[1]);
$json = $json[0];
$mycontent = file_get_contents($json);
$response = json_decode($mycontent, true);
$qualities = array_keys($response)
print_r($qualities);
?>
