我正在尝试从服务器执行脚本，从MySQL查询中检索参数并存储到structure(list(Datum = structure(c(505L, 504L, 503L,
502L, 501L, 500L), .Label = c("2016-03-03", "2016-03-04", "2016-03-05",
"2016-03-06", "2016-03-07", "2016-03-08", "2016-03-09", "2016-03-10",
"2016-03-11", "2016-03-12", "2016-03-13", "2016-03-14", "2016-03-15",
"2016-03-16", "2016-03-17", "2016-03-18", "2016-03-19", "2016-03-20",
...
"2017-07-17", "2017-07-18", "2017-07-19", "2017-07-20", "2017-07-21",
"2017-07-22", "2017-07-23"), class = "factor"), Amount = c(1700500L,
2286600L, 3018700L, 2012100L, 2357600L, 1983500L), DM50 = c(230L,
294L, 454L, 267L, 316L, 270L), DM10 = c(226L, 399L, 364L, 330L,
371L, 298L), DM5 = c(516L, 699L, 636L, 573L, 676L, 549L), DM1 = c(665L, 681L, 667L, 606L, 686L, 610L)), .Names = c("Datum", Amount", "X50", "X10", "X5", "X1"), row.names = c(NA, 6L), class = "data.frame")
有没有办法将其用作我脚本的参数？我有一个脚本存储在参数$test
$script所以我要找的是这样的：<?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, $script); //how can I use test as my paramter to execute the
?>
但是$stream = ssh2_exec($connection, '/my/path/to/script/script.sh $test');不能在引号内。
答案 0 :(得分：2)
您应该将引号更改为double并使用大括号来表达您的变量，如下所示：
$stream = ssh2_exec($connection, "{$script} {$test}");
甚至没有像这样的花括号：
$stream = ssh2_exec($connection, "$script $test");
