Php Cookies

first of all what is the need of cookie ?
Why we use cookie ?

Lets discuss it.
With the use of POST and GET method we can fetch the data which is transfer from previous page , but suppose we want that data in all pages of my site mean throughout the site then ?

Then the solution is Cookie.
When you create a cookie, using the function setcookie, you must specify three arguments.
These arguments are setcookie(name, value, expiration):

 name: The name of your cookie. You will use this name to later retrieve your cookie, so don't forget it!
 value: The value that is stored in your cookie. Common values are username(string) and last visit(date).
 expiration:   The date when the cookie will expire and be deleted. If you do not set this expiration date, then it will be treated as a session cookie and be removed when the browser is restarted.

Setcookie 

<?php
 
 //Calculate 60 days in the future
//seconds * minutes * hours * days + current time
 $inTwoMonths = 60 * 60 * 24 * 60 + time(); 
 
setcookie('name of cookie',date("G:i - m/d/y"),$inTwoMonths); 
 
 ?>
 

Retrieving Your Cookie

<?php
 
 if(isset($_COOKIE['name of ur cookie']))
 $visit = $_COOKIE['lastVisit']; 
else
 echo "You've got some stale cookies!";

echo "Your last visit was - ". $visit;
 
 ?>

Number Format In Javascript

Number.toFixed() :                                 Formats any number for "x" number of trailing decimals. The number is rounded up, and "0"s are used after the decimal point if needed to create the desired decimal length.   var profits=2489.8237 profits.toFixed(3) //returns 2489.824 (round up) profits.toFixed(2) //returns 2489.82 profits.toFixed(7) //returns 2489.8237000 (padding)   Number.toPrecision() :                                   Formats any number so it is of "x" length. Also called significant digits. A decimal point and "0"s are used if needed to create the desired length.   var anumber=123.45 anumber.toPreci...

Difference between == and === in php

Two of the many comparison operators used by PHP are '==' (i.e. equal) and '===' (i.e. identical). The difference between the two is that '==' should be used to check if the values of the two operands are equal or not. On the other hand, '===' checks the values as well as the type of operands. Let me explain more using some examples: '==' (Equal): if("22" == 22) echo "YES"; else echo "NO";      The code above will print "YES". The reason is that the values of the operands are equal. Whereas when we run the example code below: '===' (Identical): if("22" === 22) echo "YES"; else echo "NO"; The result we get is "NO". The reason is that although values of both operands are same their types are different, "22" (with quotes) is a string while 22 (w/o quotes) is an integer. But if we change the code above to t...
