Prime Number Program in PHP

-
Hello everyone, today I am going to teach the logic of basic prime number in php. Its very simple. First of all, we need to know what are prime numbers? Prime numbers are those numbers which are divisible by 1 and its own number. Like 1,3,5,7,11... so on these are all prime numbers. So how we can make logic for prime number program. Let's take an example, suppose take a number 7 and find that this number is prime or not. We all know that 7 is divisible by 1. We have to test divisible one by one number that comes after 1 or one less than a given number. Like: 2,3,4,5,6, if 7 is not divisible by any of these numbers then it is prime otherwise not.  The number which is divisible by any number which is one less than the given number except 1 then it is not a prime number. Program in php: <?php function IsPrimeNumber($num) {   for($i=2; $i<$num; $i++)     {       if($num%$i == 0)       {    return false; ...

Keyword Difficulty vs. Size of Domain

You might wonder, when it comes to competitive keywords, does Google prefer ranking big domains? This question can be answered by taking a close, detailed look at the relationship between keyword difficulty and the size of the domain. The result of this study is important, because it will lead us to a deeper understanding of the behavior of Google’s ranking algorithm when it comes to ranking competitive keywords (in relation to both small and large domains). Definition of the Factors To quantify keyword difficulty, you will associate it with the keyword searches; the higher the keyword search volume, the more competitive the keyword, in most cases. We can look not only at the amount of search volume, but also the number of indexed pages in Google containing the exact term. The higher the number of competing pages, the more the keyword would tend to be competitive.  Therefore, to give a mathematical definition, keyword difficulty can be approximated by the foll...
