An excellent resource for all these questions is the documentation found
at http://www.php.net/docs.php. Below, I've provided some links to the
specfic docs for each question.
1- MD5 with PHP values.

2- Random values in PHP.

3- Inserting values to mySQL DB by PHP and importing from them
also to send echo. (For example : after MD 5some strings in PHP
I want to insert them into the database also then to echo these
MD5 strings).

4- How to echo something.

5- How to make some GET values like :

them to the database.
