    copied!<p>I am having a strange issue with the following function that I have written. Briefly, this function connects to a URL and fetches the output by using curl functions. However, when I execute this function, I get a "server unexpectedly dropped the connection" message:</p> <pre><code>/** * Connects to remote URL and posts parameters, returns the result * * @param string $URL * @param string $ArrayPostParameters * @param string $HTTPRequestType * @param string $HTTPAuth * @param string $HTTPAuthUsername * @param string $HTTPAuthPassword * @param string $ConnectTimeOutSeconds * @param string $ReturnHeaders * @return array * @author xxxxxxxxxx */ function DataPostToRemoteURL($URL, $ArrayPostParameters, $HTTPRequestType = 'POST', $HTTPAuth = false, $HTTPAuthUsername = '', $HTTPAuthPassword = '', $ConnectTimeOutSeconds = 1, $ReturnHeaders = false) { $PostParameters = implode('&amp;', $ArrayPostParameters); $CurlHandler = curl_init(); curl_setopt($CurlHandler, CURLOPT_URL, $URL); if ($HTTPRequestType == 'GET') { curl_setopt($CurlHandler, CURLOPT_HTTPGET, true); } elseif ($HTTPRequestType == 'PUT') { curl_setopt($CurlHandler, CURLOPT_PUT, true); } elseif ($HTTPRequestType == 'DELETE') { curl_setopt($CurlHandler, CURLOPT_CUSTOMREQUEST, 'DELETE'); } else { curl_setopt($CurlHandler, CURLOPT_POST, true); curl_setopt($CurlHandler, CURLOPT_POSTFIELDS, $PostParameters); } curl_setopt($CurlHandler, CURLOPT_RETURNTRANSFER, 1); curl_setopt($CurlHandler, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($CurlHandler, CURLOPT_FOLLOWLOCATION, 5); curl_setopt($CurlHandler, CURLOPT_CONNECTTIMEOUT, $ConnectTimeOutSeconds); curl_setopt($CurlHandler, CURLOPT_TIMEOUT, $ConnectTimeOutSeconds); curl_setopt($CurlHandler, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.3) Gecko/2008092417 Firefox/3.0.3'); // The option doesn't work with safe mode or when open_basedir is set. if ((ini_get('safe_mode') != false) &amp;&amp; (ini_get('open_basedir') != false)) { curl_setopt($CurlHandler, CURLOPT_FOLLOWLOCATION, true); } if ($ReturnHeaders == true) { curl_setopt($CurlHandler, CURLOPT_HEADER, true); } else { curl_setopt($CurlHandler, CURLOPT_HEADER, false); } if ($HTTPAuth == true) { curl_setopt($CurlHandler, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); curl_setopt($CurlHandler, CURLOPT_USERPWD, $HTTPAuthUsername.':'.$HTTPAuthPassword); } $RemoteContent = curl_exec($CurlHandler); if (curl_error($CurlHandler) != '') { return array(false, curl_error($CurlHandler)); } curl_close($CurlHandler); return array(true, $RemoteContent); } </code></pre> <p>When I debugged the function, I noticed that curl_exec() function causes this issue. No curl_error message and no PHP error is generated.</p> <p>Do you have any idea about reason(s)? safe_mode is disabled in PHP.INI for your information.</p> <p>Thanks for your help in advance!</p>
