SERVER CODES

[SOLVED] “Could not reliably determine the server’s fully qualified domain name, using … for ServerName”

You might probably faced the same following error while you were restarting the Apache server on Ubuntu.

$ sudo /etc/init.d/apache2 restart
* Restarting web server apache2 apache2: Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName
… waiting apache2: Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName

To fix that problem, you need to edit the httpd.conf file. Open the terminal and type,

$ sudo gedit /etc/apache2/httpd.conf

By default httpd.conf file will be blank. Now, simply add the following line to the file.
ServerName localhost

Save the file and exit from gEdit.

Finally restart the server.
$ sudo /etc/init.d/apache2 restart

if (isset($HTTP_POST_VARS)) {

$fruit = $HTTP_POST_VARS["fruit"];

echo("Fruits chosen: " . count($fruit) . "<br><br>");

if (count($fruit)>0) {

echo("You chose the following fruits:<br>");

}

for ($i=0; $i<count($fruit); $i++) {

echo( ($i+1) . ") " . $fruit[$i] . "<br>");

}

Choose a fruit:<br><br>

<input type="checkbox" name="fruit[]" value="apples">apples <br>

<input type="checkbox" name="fruit[]" value="oranges">oranges <br>

<input type="checkbox" name="fruit[]" value="peaches">peaches <br>

<input type="checkbox" name="fruit[]" value="mangos">mangos<br>

Email format validation in Php using regular expressions

never ever include filename which you are including in htaccess url

example: RewriteRule ^admin/profile /admin.php?file=profile [NC]

in this first name after “domainname or ^ ” and filename you are using for reference is same

“ ^admin/” = “/admin.php?file=profile”

so give another name for filename reference.

like this RewriteRule ^admin/profile /master.php?file=profile [NC]

it worked.
