This is a trick using Google Profile.
First of all we are going to set a variable with a Google E-mail address (Gmail address). We are going to set it with my E-mail address

$email=’subins2000@gmail.com’; 

Then we are going to split @ from the mail address.

Using Regex to validate E-mail and Phone Number

January 26, 2013 JavaScript, Mobile, RegEx

Here is the RegEx expression to validate Phone number and E-mail.

RegEx expression for validating E-mail :

/^(([^<>()[].,;:s@"]+(.[^<>()[].,;:s@"]+)*)|(".+"))@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}])|(([a-zA-Z-0-9]+.)+[a-zA-Z]{2,}))$/

and the RegEx expression for validating Phone number :

/^(?([0-9]{3}))?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/

Here is an example of usage of these RegEx expressions in JavaScript.

var emailregex=/^(([^<>()[].,;:s@"]+(.[^<>()[].,;:s@"]+)*)|(".+"))@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}])|(([a-zA-Z-0-9]+.)+[a-zA-Z]{2,}))$/;var phoneregex=/^(?([0-9]{3}))?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/;if (emailregex.test(string)){// valid email}else{// Invalid email}if (phoneregex.test(string)){// valid phone number}else{// Invalid phone number}

You can replace string with whatever you want. For Example:

The project was created under 30 minutes and the lines of code is less that 64.
It’s written in PHP as you already know it. 
The shortened URL only has 13 characters (without HTTP://).
The shortened URL will not have .php extension. I will tell you how to view page without file extension on the next tutorial.
Enjoy Shortening URL !
