从网页运行linux命令

Question

I am trying to run command from a web page (php) to my linux server. My php page look like this: $old_path = getcwd(); chdir('/var/www'); $output = shell_exec('./test.pl'); chdir($old_path);

test.pl is a simple test file that create a txt file. If I run the command php /var/www/page.php everything works fine, but when I request the page in the browser nothing happen.

Thanks !

Make the owner of the file the apache/php user www-data:www-data

sudo chown www-data:www-data /var/www/test.pl

Give the group and others the right to execute it

chmod go+x /var/www/test.pl

Then put the absolut path into shell exec

$output = shell_exec('/var/www/test.pl');
var_dump($output);
