Test php script to check the exec php function

Gunjan — Sun, 20 Nov 2011 11:55:27 +0000

Simple php script to check if exec php function is enabled or not because many shared hosting provider by default disabled the exec php function to secure the server. You can refer the following script to check exec php function.

echo exec(‘whoami’);
?>

Now browse the URL yourdomain.com/test.php , it will show your cPanel user name if exec php function is enabled on the server and if exec php function is disabled on your domain hosted server then you will receive the following error after browsing the URL yourdomain.com/test.php

Warning: exec() has been disabled for security reasons in /home/cpanel_username/public_html/test.php on line 2

You can contact your hosting provider and ask them to enable the exec function. If you have any query let me know at nsk.gunjan@gmail.com

Send mail by using phpmail function.

Gunjan — Mon, 21 Sep 2009 04:28:58 +0000

You can create a simple php mail form by using following code..

————————–

$to = ‘supp0rt@xyz.com’;
$subject = ‘The test for mail function’;
$message = ‘Hello’;
$headers = ‘From: test@abc123.com’ . “\r\n” .
‘Reply-To: test@testforever123.com’ . “\r\n” .
‘X-Mailer: PHP/’ . phpversion();
mail($to, $subject, $message, $headers);
?>

————————–

If you are not able to receive the E-mail then you need to check whether your server is allowing to send an E-mail by using phpmail() or not?’ if you are having root login then check the servers main php.ini file.

root@Gunjan []# php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/lib
Loaded Configuration File => /usr/local/lib/php.ini

root@Gunjan []# cat /usr/local/lib/php.ini | grep disable_function
disable_functions=”system,passthru,popen,proc_close,proc_get_status,proc_nice,proc_open,proc_terminate,shell_exec,highlight_file,phpmail”

and remove the phpmail() from server mail php.ini file and restart the Apache web server.

Or

If you are not having root login details then contact your hosting provider and ask them to enable the phpmail() for your hosting account.

You can also send me an E-mail at nsk.gunjan@gmail.com if you have any queries…
