</div>


<div>
here the code I use but it return emty screen<br />

<pre><code class="code-1 nolinks" id="code-265248"><span>&lt;?PHP</span>
<span>$cmd = 'sudo /etc/init.d/ssh restart 2&gt;&amp;1';</span>
<span>exec($cmd, $output, $exitCode);</span>
<span>if ($exitCode != 0) {</span>
<span>trigger_error(&quot;Command \&quot;$cmd\&quot; failed with exit code $exitCode:</span>
<span>&quot; .</span>
<span>join(&quot;\n&quot;, $output), E_USER_ERROR);</span>
<span>?&gt;</span>
</code></pre>
</div>


<div>
This is probably a permissions problem.<br />
<br />
Put the commands in an .sh script. &nbsp;Then just call the sh script from exec();
</div>


<div>
you may also want to give php root permision, or if its an apache module you may need to give apache root permission to execute sudo commands, or you may consider using <a href="http://www.suphp.org/Home.html" rel="ugc">suphp</a><br />
Cheers<br />

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.

Scripting Languages

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
