It is silly trying to reproduce the issue in Linux, where as the problem is happening under Windows XP, as in the original report.

I can not reproduce this with proper script and using Linux. ------------------------------------------------------------------------ [2009-05-18 19:30:37] z4ns4tsu at gmail dot com string(133) "250-nameofdomain.com [192.168.10.100], this server offers 4 extensions 250-AUTH LOGIN 250-SIZE 30485760 250-HELP 250 AUTH=LOGIN " And then it hangs. ------------------------------------------------------------------------ [2009-05-14 21:58:20] jani@php.net What DOES it return? Put 'var_dump($out);' inside the loop. ------------------------------------------------------------------------ [2009-05-12 19:54:08] z4ns4tsu at gmail dot com Description: ------------ I am initiating a socket to an SMTP server to send a message. After transmitting the EHLO, I need to wait for a variable number of lines to be returned, so I am using a do{..}while() loop to check if there is nothing more to be read from the socket before sending the next command. The program, however, falls into an endless wait because socket_read() is never returning an empty string (like the documentation says it will) or FALSE (like some other bug reports say it will). I have tried with both the PHP_BINARY_READ and PHP_NORMAL_READ flags set as well as with no flags set at all. Reproduce code: --------------- foreach($mail_head as $in) { $output = ""; $in .= "\r\n"; echo $in; @socket_write($socket, $in, strlen($in)) or die("Error writing to socket: " . socket_strerror(socket_last_error())); do { $out = false; $out = socket_read($socket, 1024); $output .= $out; } while($out !== false && $out !== ''); if(!preg_match('/^[23]/', $output)) { die("Error: Mail server did not return the expected response."); } } Expected result: ---------------- EHLO fake.domain 250-this server offers 4 extensions 250-AUTH LOGIN 250-SIZE 30485760 250-HELP 250 AUTH=LOGIN MAIL FROM:<address@fake.domain> 250 Requested mail action okay, completed ... Actual result: -------------- EHLO fake.domain <nothing> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=48249&edit=1
