I need to get a random value with php function *array_rand*.
$input = array("Neo", "Morpheus", "Trinity", "Cypher", "Tank");
$rand_keys = array_rand($input, 2);
echo $input[$rand_keys[0]] . "\n";
echo $input[$rand_keys[1]] . "\n";
How to can I get value from this? Like a $input[$rand_keys];
Thanks in advance.
So many ways to do it, including simple loops... Here's probably the most compact one-liner:
$randValues = array_intersect_key($input, array_flip(array_rand($input, 2)));
array_flip() expects parameter 1 to be array and ` array_intersect_key(): Argument #2 is not an array` ...... do u have any solution for that..
$input[array_rand($input)]. The return value of array_rand is very different for 1 and >1.I haven't seen a built-in way yet. I tend to do something like this:
$rand_values = array_map(
function($key) use ($input) { return $input[$key]; },
$rand_keys
);
But that's because i thoroughly detest repeating myself. :P
You are using it correctly. array_rand returns a set of keys for random entries of your array. In your case, though, if you want to pick all entries in a randomized fashion you should be using:
$rand_keys = array_rand($input, 5);
If you want an array out of this, you could just do $rand_values = array($input[$rand_keys[0]], $input[$rand_keys[1]], $input[$rand_keys[2]], $input[$rand_keys[3]], $input[$rand_keys[4]]);.
Change: $rand_keys = array_rand($input, 2); to $rand_keys = array_rand($input, 1);
