I successfully used fgets in PHP4

examples

<?php
$stderr 
fgets(ssh2_fetch_stream($channelSSH2_STREAM_STDERR), 8192);

$str fgets(ssh2_fetch_stream($channelSSH2_STREAM_STDIO), 8192);
?>

In addition to the last post from Ricardo Striquer:

Simple block the stream with stream_set_blocking(), and you dont have to sleep() the script...

<?php
stdout_stream 
ssh2_exec($connection"/bin/lssss -la /tmp");

$err_stream ssh2_fetch_stream($stdout_streamSSH2_STREAM_STDERR);

$dio_stream ssh2_fetch_stream($stdout_streamSSH2_STREAM_STDDIO);

stream_set_blocking($err_streamtrue);
stream_set_blocking($dio_streamtrue);

$result_err stream_get_contents($err_stream));
$result_dio stream_get_contents($dio_stream));
?>

I got a friend using those functions and he was not able to use this ssh2_fetch_stream function. First of all I got the ssh2_shell sample by webmaster at spectreanime dot com, but this function does not work with his sample, i believe thats because he use fwrite instead of ssh2_shell or ssh2_exec to run the command.

This sample below is to run under a command line and is fully functional. note that i add the sleep as advised by webmaster at spectreanime dot com

<?php
echo "Connexion SSH ";
if (!(
$connection=@ssh2_connect("69.69.69.69"22))) {
   echo 
"[FAILED]\n";
   exit(
1);
}
echo 
"[OK]\nAuthentification ";

if (!@
ssh2_auth_password($connection,"root","YourPassword")) {
   echo 
"[FAILED]\n";
   exit(
1);
}
echo 
"[OK]\n";

$stdout_stream ssh2_exec($connection"/bin/lssss -la /tmp");
sleep(1);
$stderr_stream ssh2_fetch_stream($stdout_streamSSH2_STREAM_STDERR);

echo 
"Erros encontrados!\n------------\n";
while(
$line fgets($stderr_stream)) { flush(); echo $line."\n"; }
echo 
"------------\n";

while(
$line fgets($stdout_stream)) { flush(); echo $line."\n";}

fclose($stdout_stream);
?>
