preg_match不允许带空格的搜索

Question

四处寻找解决这个问题的方法。我的搜索是从Mu-6 search中获取JSON数据，但是搜索只适用于单个单词，例如搜索‘妈妈’或'mia‘返回的结果，但是搜索'mamma’并不返回结果。API使用的是UTF-8，我的文档被设置为相同的。我试图用preg_match来解决这个问题。有关index.php页面，请参见下面的my：

输入带有空格的搜索查询以返回结果后，我期望的。例如“妈妈咪呀”

实际结果没有搜索结果。只有当用户搜索单个短语“妈妈”或“米亚”时才有效

下面是一个工作页面：http://songfind.co.uk/lyrics-find

Answer 1

试试这个；

$query = $_GET['term'];
$queryEncoded = urlencode($query); <-- I encoded search term.
$apikey = 'MYAPIKEY';
$apicall = 'http://api.musixmatch.com/ws/1.1/track.search?q_track='.$queryEncoded.'&apikey='.$apikey;
