How do I pick a random value from an array?

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: $onenumber\n\n";

?>

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
