It has a socket connection that waits for an incoming request from the web
site, and then it takes what was sent from the web site, processes it, and
sends a response. here's some code:
Perl:
#!/usr/bin/perl
use IO::Socket;
$SIG{CHLD} = sub { wait () };
my $nc_sock = new IO::Socket::INET (
LocalHost => '192.168.3.4',
LocalPort => '7070',
Proto => 'tcp',
Listen => 5,
Reuse => 1
);
while ( $nclive_sock = $nc_sock->accept() )
{
$pid = fork();
if ($pid == 0) {
while ( defined( $buf = <$nclive_sock> ) )
{
print $buf;
if ( substr( $buf, 0, 3 ) eq '000' )
{
print $nclive_sock
"4230999999000000004111111111111111470002220001999977777777777777777777423\n
";
} else {
print $nclive_sock "Hello to you too!\n";
}
}
exit(0);
}
}
close ( $nc_sock );
Here is the PHP Web site:
$fp = fsockopen ("192.168.3.4", 7070, $errno, $errstr, 90);
if ( !$fp )
{
echo "$errstr ($errno)<br>\n";
} else {
fputs ( $fp, "$auth_msg\n" );
$response = process_response( fgets( $fp ) );
printf( "%s - %s",
process_code( $response['code'] ), $response['msg'] );
fclose( $fp );
}
Hope that helps...
