我有一个字符串 ($source)，其中包含以下数据：

{"Title":"War Horse","Year":"2011","Rated":"PG-13","Released":"25 Dec 2011","Runtime":"2 h 26 min","Genre":"Drama, War","Director":"Steven Spielberg","Writer":"Lee Hall, Richard Curtis","Actors":"Jeremy Irvine, Emily Watson, David Thewlis, Benedict Cumberbatch","Plot":"Young Albert enlists to serve in World War I after his beloved horse is sold to the cavalry. Albert's hopeful journey takes him out of England and across Europe as the war rages on.","Poster":"http://ia.media-imdb.com/images/M/MV5BMTU5MjgyNDY2NV5BMl5BanBnXkFtZTcwNjExNDc1Nw@@._V1_SX640.jpg","imdbRating":"7.2","imdbVotes":"39,540","imdbID":"tt1568911","Response":"True"}

我正在使用以下方法提取标题、类型、情节等：

foreach(str_getcsv($source) as $item) {
    list($k, $v) = explode(':', $item);
    $$k = str_replace('"', '', $v);
    }

到目前为止，这很好用，我可以使用 $Title、$Genre 等。唯一不起作用的是海报的 URL，因为我正在分解“：”并且 URL - 当然 - 包含“：”（在“http”之后）。

如何将海报 URL 放入变量中？

这看起来像 JSON 数据，为什么不简单：

$txt = '{"Title etc.....}';
$data = json_decode($txt);

$title = $data['Title'];
$genre = $data['Genre'];
etc...

可变变量非常难看，并且您可能会通过使用 JSON 数据的内容覆盖其他一些变量来危及您的代码。

如果你真的坚持使用自动激活的变量来污染你的命名空间，你总是可以extract()用来拆开数组

它是一个json，

你应该使用json_decode

$str = '{"Title":"War Horse","Year":"2011","Rated":"PG-13","Released":"25 Dec 2011","Runtime":"2 h 26 min","Genre":"Drama, War","Director":"Steven Spielberg","Writer":"Lee Hall, Richard Curtis","Actors":"Jeremy Irvine, Emily Watson, David Thewlis, Benedict Cumberbatch","Plot":"Young Albert enlists to serve in World War I after his beloved horse is sold to the cavalry. Albert\'s hopeful journey takes him out of England and across Europe as the war rages on.","Poster":"http://ia.media-imdb.com/images/M/MV5BMTU5MjgyNDY2NV5BMl5BanBnXkFtZTcwNjExNDc1Nw@@._V1_SX640.jpg","imdbRating":"7.2","imdbVotes":"39,540","imdbID":"tt1568911","Response":"True"}';
$arr = json_decode($str,true); 
print_r($arr);
echo $arr['Title'];
echo $arr['Year'];

注意，我已经正确地转义了字符串。

使用json_decode

$str = '{"Title":"War Horse","Year":"2011","Rated":"PG-13","Released":"25 Dec 2011","Runtime":"2 h 26 min","Genre":"Drama, War","Director":"Steven Spielberg","Writer":"Lee Hall, Richard Curtis","Actors":"Jeremy Irvine, Emily Watson, David Thewlis, Benedict Cumberbatch","Plot":"Young Albert enlists to serve in World War I after his beloved horse is sold to the cavalry. Albert\'s hopeful journey takes him out of England and across Europe as the war rages on.","Poster":"http://ia.media-imdb.com/images/M/MV5BMTU5MjgyNDY2NV5BMl5BanBnXkFtZTcwNjExNDc1Nw@@._V1_SX640.jpg","imdbRating":"7.2","imdbVotes":"39,540","imdbID":"tt1568911","Response":"True"}';

$decode_string = json_decode($str);

print_r($decode_string);
echo $decode_string->Title;
