PHP - Multi line random array.

Question

Say we have an array like this with 1 being two values and 2 being two values and 3, etc

$language = array 
(
    "1"=>array
    (
      "Hola",
      "Spanish"
    ),
    "2"=>array
    (
      "Fáilte",
      "Irish"
    ),
    "3"=>array
    (
      "Yasou",
      "Greek"
    )
);

How would I randomly select ONLY 1 of 3 arrays and display the two values it has.

So something like this, $language[2][1], thats in $language[2][2].
Which should be, Fáilte, thats in Greek

Answer 1

You can choose a random set of words using the following code and then echo the two results like so:

$row = rand(0,sizeof($language)-1);
echo $language[$row][0];
echo $language[$row][1];

This is assuming that your array actually starts from 0 as most arrays do. If it really starts from 1, you can use the code posted in the answer below instead.

Answer 2

PHP has it's own random array function: array_rand(). Use it like so:

$random_key = array_rand($language);
echo $language[$random_key][0];
echo $language[$random_key][1];
