傳遞一個變量從PHP到bash

我似乎無法得到一個變量傳遞給我的bash腳本從PHP。無論我嘗試什麼，$ uaddress和$ upassword都是空的。傳遞一個變量從PHP到bash

您需要將變量作爲參數傳遞給shell腳本，並且shell腳本必須讀取其參數。

所以在PHP中：

$useraddress = escapeshellarg('[email protected]'); 
$upassword = escapeshellarg('test1234'); 
$addr = shell_exec("sudo /home/tpccmedia/cgi-bin/member_add_postfixadmin $useraddress $upassword 2>&1");

，並在shell腳本：

useraddress=$1 
upassword=$2

你也肯定想逃避參數[escapeshellarg]（http://www.php.net/manual/en/function.escapeshellarg.php） - 尤其是可能的密碼字段包含特殊字符。 – tangrs

@tangrs謝謝。我也忘了將字符串的單引號改爲雙引號，這樣插值就可以工作。 – Barmar

@Barmar no sir，$ useraddress = escapeshellarg（$ useraddress）;給出一個未定義的變量，escapeshellarg（'$ useraddress'）實際上會傳遞給BASH，但是作爲一個字符串。 http://paste.ee/p/arOIF http://bpaste.net/show/141824/ – brad

明白了。

<?php 
$upassword = 'test1234'; $uaddress = '[email protected]'; 
$uaddress = escapeshellarg($uaddress); 
$upassword = escapeshellarg($upassword); 
$addr = shell_exec("sudo /home/tpcmedia/cgi-bin/member_add_postfixadmin $uaddress $upassword 2>&1"); 
?> 


#!/bin/bash -x 
uaddress=$1 
upassword=$2 
ssh -p 2222 -6 2400:8900::f03c:91ff:fe69:8aaf "/var/www/localhost/htdocs/postfixadmin/scripts/postfixadmin-cli mailbox add" $uaddress --password $upassword --password2 $upassword
