Pass cmd commands via php script
<p>Here is my php code</p>

<pre><code>$command = "C:\Program Files\ClustalW2&gt;clustalw2 -INFILE=seq.txt -TYPE=Protein -OUTFILE=res.aln";
exec($command);
</code></pre>

<p>When i run the command using the cmd, it generates the desired file. However when i try passing the same command via my php code it generates no result. How do i fix this problem?</p>
