Age calculation is a tricky calculation especially in Programming Languages. I’m going to tell you a simple way to find out age in PHP. This is a simple function that will calculate age if it is given a birthday date in the format date/month/year. For example : 20/01/2000 or 04/12/1990
Here is the function :

function age($birthday){
 list($day,$month,$year) = explode("/",$birthday);
 $year_diff  = date("Y") – $year;
 $month_diff = date("m") – $month;
 $day_diff   = date("d") – $day;
 if ($day_diff < 0 && $month_diff==0){$year_diff–;}
 if ($day_diff < 0 && $month_diff < 0){$year_diff–;}
 return $year_diff;
}

This is a simple trick. Most of the web developers worry that the Stylesheet file will not load completely. This happens if your CSS file’s size is too large. The fail in complete loading of the file mostly happens to users who are using slower connections like me.

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.

list($id, $domain) = split("@",$email);

Next we are going to send a request to Google Profiles to fetch the IMAGE url.

$headers = get_headers("https://profiles.google.com/s2/photos/profile/".$id, 1);

The variable $id above is from the splitted part.
Finally we have to get the URL of the user’s profile picture.
