PHP +运行bash脚本来创建文件 [英] PHP + Run bash script to create file

问题描述

在除了我的<一个href=\"http://stackoverflow.com/questions/11052162/run-bash-command-from-php/11052453#comment14460416_11052453\">$p$pvious问题，另一个问题出现了，我决定把它一个新的问题：

In addition to my previous question, another problem appeared and I decided to make a new question for it:

我目前正在调用PHP脚本，比运行bash脚本。 PHP脚本如下：

I am currently calling a php script that than runs a bash script. The php script looks like:

chdir('/home/');
$output = shell_exec('./do.sh');
echo "<pre>$output</pre>";

该do.sh包括：

The do.sh contains:

#! /bin/bash

echo 12;
dd if=/dev/urandom of=test.test bs=1048576 count=2

问题是以下几点：

The problem is following:

当我称之为 ./ do.sh 从终端一切正常：test.test创建和输出中的 12

When I call ./do.sh from the terminal everything works fine: test.test is created and the ouput is 12

然而，当我把它从我的PHP文件，输出为 12 藏汉，但正在创建没有文件。因为我几乎一无所知bash脚本编程，我不知道为什么会这样...

However, when I call it from my php file, the output is 12 aswell, but no file is being created. Since I know almost nothing about bash scripting, I have no idea why this is happening...

推荐答案

检查PHP safe_mode设置被启用。你必须关闭它在你的/etc/php.ini中的文件，显然，检查文件系统权限。

Check if PHP safe_mode is enabled. You have to turn it off in your /etc/php.ini file, and obviously check filesystem permissions.
