Bug description: socket_read not returning on no more data to read
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:<addr...@fake.domain>
250 Requested mail action okay, completed
...
Actual result:
--------------
EHLO fake.domain
<nothing>
