I cobbled my script up from bits of the 3rd-party application I'm trying to get running. I know little enough about PHP that I didn't notice the '@', nor did I know its significance. My updated script is below. PHP now reports the following: Warning: fsockopen() [function.fsockopen]: unable to connect to localhost:110 (Unknown error) in C:\Inetpub\wwwroot\socket_test.php on line 12 errno is still 0. "Unknown error" sounds straight from Windows' carefully-crafted assortment of information-free error messages. :) >From http://us2.php.net/manual/en/function.fsockopen.php: "If the value returned in errno is 0 and the function returned FALSE, it is an indication that the error occurred before the connect() call. This is most likely due to a problem initializing the socket." Keep in mind that the fsockopen() call succeeds when run from the command line. My suspicion is that IIS is preventing PHP from opening the socket, but I can't find anything on the Web discussing this either in terms of IIS alone or it in conjuction with PHP. <?php $host = "localhost"; $port = "110"; error_reporting(E_ALL); ?> <html> <h1>Attempting to open socket on host '<?php echo ("$host")?>' at port '<?php echo ("$port")?>'</h1> <h2> <?php $errno = 0; $errstr = "<no error reported>"; $fp = fsockopen($host, $port, $errno, $errstr); if ($fp) { echo "Socket connection established"; fclose($fp); } else { echo "Could not connect to $host at port $port (\$errno=$errno; \$errstr=$errstr)"; } ?> </h2> </html> -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
