I had this problem on debian.

What helped is installing the nss version of curl:

<pre><code>apt-get install libcurl4-nss-dev
</code></pre>

Then reinstall <code>pecl_http</code>, and give the following path when it asks for libcurl

<pre><code>/usr/lib/x86_64-linux-gnu/libcurl.so
</code></pre>

Here is a cool gist, called <a href="https://gist.github.com/ajaxray/11117042" rel="nofollow">Using version 2 of PECL HTTP extension (pecl_http)</a>. I did not write this but it shows a few good examples of how to use version 2.

if you are using redhat install curl-dev and then uninstall and install again pecl_http.

<pre><code>sudo yum install curl-devel
</code></pre>

Hope this helps someone.

I just saw that there is a new version of the pecl_http extension available, see <a href="http://devel-m6w6.rhcloud.com/mdref/http" rel="nofollow">the documentation</a>. It brings a new interface and has no similarity to the old extension, so I would like to ask wether there are any examples on how to make the extension work? I installed it and the requirements raphf and propro, too. But even a simple 

<pre><code>$client = new http\Client();
</code></pre>

gives me a fatal error 

<pre><code>Uncaught exception 'http\Exception\UnexpectedValueException' with message 'Failed to locate "(null)" client request handler' in
</code></pre>

Same goes for 

<pre><code>$client = new http\Client('curl');
</code></pre>

just with <code>Failed to locate "curl"</code>.

I would like to see a working example of the instantiation of http\Client and a simple GET request to a website.

我刚刚看到有一个新版本的pecl_http扩展可用，请参见。它带来了一个新的接口，与旧的扩展没有任何相似之处，所以我想问一下，有没有关于如何使扩展工作的例子？我安装了它，也安装了对raphf和propro的要求。但即使是一个简单的$client = new http\Client();给了我一个致命的错误Uncaugh...
