How would I randomly get both values from this array?

[cloudll]

Hey guys. I have this array:

$isValid = array
  (array(200,200),
  array(250,250),
  array(425,425)
  );

echo $isValid[1][0] . "<br />" . $isValid[1][1];

I tried to use array_rand but cannot get it working with more than one value. Is there a way I can randomly echo either:

 

200,200

250,250

or

425,425?

 

Thanks for any tips

So you want to select one of the three sub-arrays and then get both items of that array?

<?php

$strange_number_pairs = [
    [200, 200],
    [250, 250],
    [425, 425],
];

$rand_pair = $strange_number_pairs[mt_rand(0, count($strange_number_pairs) - 1)];

echo $rand_pair[0].'<br>'.$rand_pair[1];

Of course I have no idea what those numbers mean and why you would store the same number twice.
