PHP使用ssh2_exec来执行带有查询参数的脚本

Question

我正在尝试从服务器执行脚本，该参数是从MySQL查询中检索并存储到$test是否可以将其用作脚本的参数？ 我还有一个存储在参数$script

<?php

include("db.php");  
$user = 'user';
$password = 'pwd';

$script = '/my/path/to/script/script.sh';

...

$testResult = mysqli_query($dbConnection, $queryNextTest);
$test = $testResult->fetch_object()->test_script; //this is my parameter obtained from query

$stream = ssh2_exec($connection, $script); //how can I use test as my paramter to execute the 

?>

所以我正在寻找的是这样的东西： $stream = ssh2_exec($connection, '/my/path/to/script/script.sh $test'); 但是$test不能在引号内。

您应该将引号更改为double并使用大括号来表示变量，如下所示：

$stream = ssh2_exec($connection, "{$script} {$test}");

甚至没有这样的花括号：

$stream = ssh2_exec($connection, "$script $test");
