Apaceh Error - Open as .phtml file ?

I have installed the Apache server using apt-get in ubuntu. I also installed php5 library files.

But while trying to open .php files , it gives the pop-up like

"open as .phtml file ?"

On google, we can see more posts on this error. Most of them mentioned to add the following lines

in httpd.conf,


<ifmodule>
AddType application/x-httpd-php .php .phtml .php3
AddType application/x-httpd-php-source .phps
</ifmodule>


But in my system , it already added by php5 library installation.

Some of them mentioned to clear the browser cache.

Yes ! Its work for me....;-)

Usage of SAJAX

Small example for the usage of sajax . It is explained according to the
function flow

step 1.) Calling javascript function using button (CLIENT SIDE)

<input class="button" name="test" value="Test" type="test">

onclick=ajax_test();>

step 2.) Function definition … Here it calls server function which is named as “loading” … (CLIENT SIDE)

function ajax_test()
{
alert (”sdsdf”)
x_loading(ajax_test_diaplay)
}

Note: Here ajax_test_display is a function which will handle the
returned result

step 3.) PHP Coding .. (SERVER SIDE) (you should include Sajax2.php file)

function loading()
{
return (”balavignesh”);
}
sajax_export(”loading”);

step 4.) Displaying the result (CLIENT SIDE)

function ajax_test_diaplay(ret_value)
{
alert (ret_value)
}

Installing Fonts on Ubuntu

Just copy your font into your users

font folder ~/.fonts (”~” represents the path to your home dir e.g.

/home/bala/.fonts). If it doesn’t exist then create it. Then

exectue the font cache command from the terminal.

sudo fc-cache -vf

• -v option is for verbose or it tells you exactly what the command is doing.
• -f option forces updating of all cached font files

This updates the font cache on your system and you should be able to use the fonts right away.
