exec() doesnot work??

[dinesh1440]

When I run a command "blastp -query query.fasta -subject arbi.fasta " it gives the output in command promt. But it did not when used in exec as follows:

$out=exec('blastp -query query.fasta -subject arbi.fasta')
echo $out;

please help me in this..

Try:

// $out will contain the last line of the command
$out=exec('blastp -query query.fasta -subject arbi.fasta', $output, $return_var);
 
echo '<pre> The last line of output:<br>';
echo $out.'<br>';
echo 'The output:<br>';
print_r($output);
echo '<br>The status: '.$return_var;
echo '</pre>';
 

If this doesn't work try passthru()

Also, the user the webserver is running as may not have execute permissions for the executable... Just a thought...

You may check your php.ini file , if their exec is permitted or not....
