在NetBeans上使用XDebug进行卷曲

Question

I have a strange problem when trying to debug with Xdebug on Netbeans ( on Windows 8 ) a curl request. Here is my code:

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "http://localhost");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

    $response = curl_exec($ch);
    if ( curl_errno($ch) ) {
        $result = 'ERROR -> ' . curl_errno($ch) . ': ' . curl_error($ch);
        echo $result;
    }

    print "
 response = 
";
    var_dump($response);

    // close cURL resource, and free up system resources
    curl_close($ch);

    die;

When I debug with Netbeans I get:

ERROR -> 28: Operation timed out after 10015 milliseconds with 0 out of -1 bytes  receivedresponse = bool(false)

When I just run without debug I get no error and a response of a xampp page.

In php.ini I have:

[XDebug]
zend_extension = "C:\xampp\php\ext\php_xdebug-2.2.5-5.4-vc9.dll"
xdebug.profiler_append = 0
xdebug.profiler_enable = 1
xdebug.profiler_enable_trigger = 0 
xdebug.profiler_output_dir = "C:\xampp\tmp"
xdebug.profiler_output_name = "cachegrind.out.%t-%s"
xdebug.remote_enable = 1
xdebug.remote_handler = "dbgp"
xdebug.remote_autostart = 1
xdebug.remote_host = "127.0.0.1"
xdebug.remote_port = "9000"
xdebug.trace_output_dir = "C:\xampp\tmp"
xdebug.max_nesting_level = 200
xdebug.idekey = "netbeans-xdebug"

I suppose that when you set xdebug.remote_autostart = 1, Xdebug will always attempt to start a remote debugging session and try to connect to a client (even if the GET/POST/COOKIE variable was not present).

May be, in your case, Xdebug try to connect Netbeans but is unable to complete the operation, which this lead Xdebug to Operation timeout error.
