Follow the steps to create Random Numbers
Getting Random Numbers in PHP:
Its very easy to get random numbers in php too.
PHP gives a method called "rand()".
Using the method we can get random numbers.
Calling rand() will return values between 0 and RAND_MAX
e.g:
<?php
$numb = rand(); //Here we create a random number
echo($numb);
?>
Result:
194165421
So now we have to get values between x to y say 50 to 66.
It can be achieved by following the example
e.g:
<?php
$numb = rand(50,66); //Here we create a random number between 50 and 66
echo($numb);
?>
Result:
54
Getting Random Numbers in javascript:
Its very easy to get random numbers in javascript.
javascript gives a method called "random()".
Using the method we can get random numbers.
Calling Math.random() will return values between 0 and 1
e.g:
<script>
var numb = random(); //Here we create a random number
document.write(numb);
</script>
Result:
So now we have to get values between x to y say 0 to 66.
It can be achieved by following the example
e.g:
<script>
var numb = Math.random(); //Here we create a random number e.g: .23xxxx
numb = numb*66; //Here we multiply the number by 66. e.g: the value will convert to 15.xxxx
numb = Math.round(numb); //Now we round of the value. e.g: the value will be rounded to 15
document.write(numb); //So we have got a random number inbetween 0 and 66
</script>
Result:
