如何從純文本響應中獲取單個數據？

Question

如何從HTTP響應中獲取單個值？它實際上是一個JSON響應，但是文本塊就好像它不是JSON。

例如，當我查詢WHOIS查詢API，我得到如下回應：

HTTP/1.1 200 
Connection: keep-alive 
Content-Type: application/json;charset=UTF-8 
Date: Sat, 12 Nov 2016 09:10:56 GMT 
Server: Mashape/5.0.6 
Transfer-Encoding: chunked 
X-Ratelimit-Requests-Limit: 11000 
X-Ratelimit-Requests-Remaining: 10991 

{ 
    "available": false, 
    "whoisResponse": "\nWhois Server Version 2.0\n\nDomain names in the .com and .net domains can now be registered\nwith many different competing registrars.

我想獲得Expiration Date分配給了whoisResponse的變量，這可能嗎？我怎樣才能在PHP中做到這一點？

試試這個

$str = "\nWhois Server Version 2.0\n\nDomain names in the .com and .net domains can now be registered\nwith many different competing registrars.

$data = preg_match('/Expiration Date: ([0-9]{2})-([a-z]{3})-([0-9]{4})/',$str,$match); 

echo '<pre>'; 
print_r($match); 
echo '</pre>'; 

可以使用preg_match匹配的字符串。
