file_get_contents(): SSL operation failed with code 1 (certificate verify failed)
<p>I have installed WAMP 3.0.4 and am trying to write a PHP script that connects to an external HTTPS web service. But this returns the error:</p>

<blockquote>
  <p>Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed</p>
</blockquote>

<p>I have written a short script that demonstrates the issue:</p>

<pre><code>&lt;?php
$auth = base64_encode('username:password');

$aContext = array(
    'http' =&gt; array(
        'proxy' =&gt; 'tcp://proxyip:proxyport',
        'request_fulluri' =&gt; true,
        'header' =&gt; 'Proxy-Authorization: Basic $auth'
    ),
    'SSL' =&gt; array(
        'verify_peer' =&gt; false,
        'verify_peer_name' =&gt; false,
        'allow_self_signed' =&gt; true,
        'cafile' =&gt; 'C:/wamp/certificates/cacert.pem'
    )
);
$cxContext = stream_context_create($aContext);

$sFile = file_get_contents("https://www.google.com", False, $cxContext);

echo $sFile;
?&gt;
</code></pre>

<p>It is a requirement to use a proxy server.</p>

<p>As can be seen, I have tried installing a root certificates bundle and also adding verify_peer to false (not that I would do that in production) but still I receive this error.</p>

<p>As can be clearly seen from the above, I am something of an Apache / WAMP novice. Can someone perhaps explain what I am missing?</p>
