Solution

Remove all previous versions of lamp and all of its components (apache, php, mysql, smtp ...) and reinstall it one by one.

Installing apache, php and mysql for ubuntu 14.04.

Step 1:

sudo apt-get update

sudo apt-get install apache2 mysql-client mysql-server php5

You could be asked for password.

Step 2:

sudo apt-get install php5-curl php5-gd php5-intl php5-mysql

sudo service apache2 restart

Step 3:

Open http://127.0.0.1

Now you have a working apache server with php and mysql.
