How to send a form's data to an e-mail or database(e-mail is prefered)?

I created this form and I want the receive the form's information whenever anyone fills my form. I want it to be sent to my e-mail or be submitted in a database but, I heard it's possible by using php can anyone give an step by step information on how to create that php file. Is it necessary to change any file permissions in my host panel?(I'm using direct admin control panel) 'Thanks for reading my question.

Here's the form:

<form action="#"> <input id="name" type="text" name='name' placeholder="Your name ... " class='span5 contact-input'/> <input id="email" type="email" name='email' placeholder="Your email ... " class='span5 contact-input' /> <textarea id="message" name="message" rows="10" class='span7 contact-input' placeholder="Your message ... "></textarea> <input id="send_message" type="submit" name="postComment" value='Send Message' class='btn btn-custom btn-red btn-medium btn-large-text' /> </form> </html>
