Running multiple commands shows this warning and second(and any next) command wont be executed:
- PHP Warning: ssh2_exec(): Unable to request a channel from remote host in ...
Solution with fclose($stream) does not work, but this is simple solution which works for me:
<?php
$connection = ssh2_connect('SOME SSH IP ADDRESS', 22);
ssh2_auth_password($connection, 'username', 'passwortd');
$stream = ssh2_exec( $connection, "screen-length 0 temporary\ndisplay isis name-table" );
stream_set_blocking( $stream, true );
$stream_out = ssh2_fetch_stream( $stream, SSH2_STREAM_STDIO );
echo stream_get_contents($stream_out);
?>
first command is: screen-length 0 temporary
second command is: display isis name-table
which is executed with \n in the same line.
You have to separete outputs of those commands later.
Looks like ssh2_exec allocates exec stream in session you are connected in, and for freeing it , you have to ssh2_disconnect.
Usualy you are ok to ssh2_exec one command then disconnect, then connect and ssh2_exec next command. This is how some other php libraries works as I have seen. But sometimes some variables are sesion dependent, and when you disconnect variables resets.
