This is the best way I found to automatically run multiple commands or commands that might take
longer then expected. NOTE: this assumes that no where in the output is there the text
'[end]' otherwise the function will end prematurely. Hope this helps people.
<?php
$ip = 'ip_address';
$user = 'username';
$pass = 'password';
$connection = ssh2_connect($ip);
ssh2_auth_password($connection,$user,$pass);
$shell = ssh2_shell($connection,"bash");
//Trick is in the start and end echos which can be executed in both *nix and windows systems.
//Do add 'cmd /C' to the start of $cmd if on a windows system.
$cmd = "echo '[start]';your commands here;echo '[end]'";
$output = user_exec($shell,$cmd);
fclose($shell);
function user_exec($shell,$cmd) {
fwrite($shell,$cmd . "\n");
$output = "";
$start = false;
$start_time = time();
$max_time = 2; //time in seconds
while(((time()-$start_time) < $max_time)) {
$line = fgets($shell);
if(!strstr($line,$cmd)) {
if(preg_match('/\[start\]/',$line)) {
$start = true;
}elseif(preg_match('/\[end\]/',$line)) {
return $output;
}elseif($start){
$output[] = $line;
}
}
}
}
