How To add a HTTPS address to your etc/hosts File

First Open your hosts file on   /etc/hosts on Linux  OR  C:\Windows\System32\drivers\etc on Windows systems

As known, the default port for web browsing is port 80, so every record inserted in the hosts file as default use port 80.

In order to add an "https" address just specify the ssl port for the desired record like so:

127.0.0.1:443    mysite.com

Now https://mysite.com will be handled by your localhost

Calculate time-diff and calculate age from birth date

On my searches I've found many many different, complicated functions for time difference and many different functions calculate age, But for such a simple task I thought there should be a simpler solution.
so here are a few good simple ways to calculate time differences and age

good and simple function that because of the versatility of strtotime function can support many different date formats:

function dateDiff($from, $to = "now")
{
return round((strtotime($to) - strtotime($from))/60/60/24);
}

and if age calculation is what you desire,
a simple function to calculate age by birth date

/**
* Calc age from MySQL date format
* @param string $date YY-mm-dd (MySQL Date Format)
*/
function calcAge($date)
{
//Break the date into an array
list($Y,$m,$d) = explode("-",$date);
//Calculate Year Diff
$age = date("Y")-$Y;
//Subtract a year if exact birth date hasn't passed yet
if(date("md") < $m.$d) $age--;
//And finally return the age
return $age;
}
