Hi Balu,
If you want to choose an entry randomly from an array then you can use the array_rand function like this:
<?php
$lottery = range(1,49);
$onenumber = array_rand($lottery);
echo "One number is: $onenumbernn";
?>
This will print a random number between 1 and 49.
You can also use array_rand to return a certain number of random numbers.
People often like to write a little computer program to generate their weekly lottery numbers for them. Here's how to create a lottery number generator for the UK lottery that picks six random numbers between 1 and 49 in just one line of PHP code:
<?php
foreach(array_rand(range(1,49),6) as $number) echo "$number ";
?>
This will print a random selection of six numbers to the screen, for instance:
27 33 48 21 19 43
