array_rand

Posted on February 16th, 2010 RubyLove 1 comment

The array_rand() function in PHP randomly selects one or more elements from an array.

PHP
```
$users = array('john', 'jane', 'tim', 'alex');
$lucky_winner = array_rand($users);
echo $lucky_winner;
// alex
```
Ruby
```
users = [ 'john', 'jane', 'tim', 'alex' ];
lucky_winner = users[rand(users.length)];
puts lucky_winner;
# => alex
```

  Actually, this is just not true.
  
  array_rand returns a random KEY of the givven array. So to get the value, you’d use:
  
  $random_value = $users[array_rand($users)];
  
  Might look strange, but is very smart, because like this you can have both the key and the value. Sort of like in ruby =) except in php in works for assoc arrays as well. SPL ftw!
