POConnection refused for PHP curl() when starting PHP webserver via exec()
text
Body
copied!<p>I'm attempting to start PHP's built-in webserver at the beginning of some unit tests. The goal is for the same script to start the webserver and then connect to it to verify our curl wrapper libraries behave appropriately. </p> <p>Script:</p> <pre><code><?php echo "Starting server...\n"; exec("php -S localhost:8000 -t /path/to/files > /dev/null & echo $!", $output); $ch = curl_init("http://localhost/"); curl_setopt($ch, CURLOPT_PORT, 8000); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_exec($ch); if(curl_errno($ch)) { echo 'Curl error: ' . curl_error($ch); } // Close handle curl_close($ch); echo "PID: ".$output[0]."\n"; exec('kill '.$output[0]); ?> </code></pre> <p>When I run the above script I get this error:</p> <pre><code>Curl error: Failed connect to localhost:8000; Connection refused </code></pre> <p>Notes:</p> <ul> <li>The webserver does start, if I remove the <code>kill</code> at the end of the script I can see the webserver running in the processlist</li> <li>If I start up PHP's webserver on the command line my PHP script can connect to it</li> <li>If I start up PHP's webserver from <em>another</em> PHP script the above script can connect to it</li> <li><code>curl</code> from the command line can connect to the PHP webserver started</li> </ul> <p>I can only guess that there's something being blocked or happening when PHP's webserver is started by a process that then attempts to connect to it?</p> <p>PHP 5.4.15</p> <p>CentOS release 5.6 (Final)</p>
