PHP cURL vs file_get_contents
提问by Salvador Dali
How do these two pieces of code differ when accessing a REST API?
访问 REST API 时，这两段代码有何不同？
$result = file_get_contents('http://api.bitly.com/v3/shorten?login=user&apiKey=key&longUrl=url');
and
和
$ch = curl_init('http://api.bitly.com/v3/shorten?login=user&apiKey=key&longUrl=url');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
They both produce the same result, judging by
他们都产生相同的结果，判断
print_r(json_decode($result))

file_get_contents()is a simple screwdriver. Great for simple GET requests where the header, HTTP request method, timeout, cookiejar, redirects, and other important things do not matter.
file_get_contents()是一把简单的螺丝刀。非常适合简单的 GET 请求，其中标头、HTTP 请求方法、超时、cookiejar、重定向和其他重要的事情都无关紧要。

In addition to this, due to some recent website hacks we had to secure our sites more. In doing so, we discovered that file_get_contentsfailed to work, where curlstill would work.
除此之外，由于最近的一些网站黑客攻击，我们不得不更多地保护我们的网站。在这样做时，我们发现file_get_contents无法工作，而curl仍然可以工作。
Not 100%, but I believe that this php.ini setting may have been blocking the file_get_contentsrequest.
不是 100%，但我相信这个 php.ini 设置可能阻止了file_get_contents请求。
; Disable allow_url_fopen for security reasons
allow_url_fopen = 0
Either way, our code now works with curl.
无论哪种方式，我们的代码现在都可以使用curl。

This is old topic but on my last test on one my API, cURL is faster and more stable. Sometimes file_get_contents on larger request need over 5 seconds when cURL need only from 1.4 to 1.9 seconds what is double faster.
这是一个老话题，但在我对我的 API 的最后一次测试中，cURL 更快更稳定。有时，较大请求上的 file_get_contents 需要超过 5 秒，而 cURL 只需要 1.4 到 1.9 秒，这是两倍快。
I need to add one note on this that I just send GET and recive JSON content. If you setup cURL properly, you will have a great response. Just "tell" to cURL what you need to send and what you need to recive and that's it.
我需要为此添加一个注释，我只发送 GET 并接收 JSON 内容。如果您正确设置了 cURL，您将获得很好的响应。只需“告诉”cURL 您需要发送什么以及您需要接收什么，就是这样。
On your exampe I would like to do this setup:
在你的例子中，我想做这个设置：
$ch = curl_init('http://api.bitly.com/v3/shorten?login=user&apiKey=key&longUrl=url');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_TIMEOUT, 3);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json'));
$result = curl_exec($ch);
This request will return data in 0.01 second max
此请求将在 0.01 秒内最多返回数据
