PHP SSH多个命令

PHP SSH多个命令,php,ssh,Php,Ssh,我正在尝试构建一个ssh脚本,以便在主机上运行多个命令。我的目标是获得每个命令的输出。我的目标主机是一个cisco路由器,为了让下面的脚本执行多个命令,我需要为我要执行的每个命令运行它,这不是一个非常优雅的解决方案 $cmd = array ('sh run int te 1/1', 'sh run int te 1/2'); for ($i = 0; $i <= 1; $i++) { $connection = ssh2_connect('10.1.1.1', 22);

$cmd = array ('sh run int te 1/1', 'sh run int te 1/2');

for ($i = 0; $i <= 1; $i++) {
    $connection = ssh2_connect('10.1.1.1', 22);
    ssh2_auth_password($connection, 'user', 'pass');
    $stream = ssh2_exec($connection, $cmd[$i]);
    stream_set_blocking($stream, true);
    $stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO);
    echo stream_get_contents($stream_out); }
cli的输出

我只从第一个命令“sh run int te 1/1”获得输出。

您正在重复连接阶段。请尝试以下方法:

$cmds = array ('sh run int te 1/1', 'sh run int te 1/2');

$connection = ssh2_connect('10.1.1.1', 22);
ssh2_auth_password($connection, 'user', 'pass');

foreach ($cmds as $cmd) {
    $stream = ssh2_exec($connection, $cmd);
    stream_set_blocking($stream, true);
    $stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO);
    echo stream_get_contents($stream_out);
}
我现在在Ubuntu机器(14.04-LTS)上进行了测试,它可以工作:

I say 'who', answer was: lserni   :0           Jan 21 11:25 (console)
I say 'date', answer was: Thu Feb 16 09:55:52 CET 2017

…嗯,除了我忘记了在那台机器上有一个打开的控制台登录之外:-(

我不建议在每个循环上启动一个新连接,而是先设置连接,然后在命令数组上循环,并将输出推送到一个数组。类似这样:

$cmds = [ 'ls', 'ps ux' ];

$connection = ssh2_connect( '127.0.0.1', 22 );
ssh2_auth_password( $connection, 'username', 'password' );

$output = [];

foreach ($cmds as $cmd) {
    $stream = ssh2_exec( $connection, $cmd );
    stream_set_blocking( $stream, true );
    $stream_out = ssh2_fetch_stream( $stream, SSH2_STREAM_STDIO );
    $output[] = stream_get_contents($stream_out);
}
这将把所有输出推送到数组
$output

现在,您可以循环$output,也可以选择为output指定YOUU命令的键,以便访问它:

$output[$cmd] = stream_get_contents($stream_out);

然后,例如,调用:
$output['ls']

是否可以使用“&&&”内爆数组,使其自动执行一个接一个的所有命令?是否可以使用“&&”内爆数组,使其自动执行一个接一个的所有命令?
