Returning random values from an array

[talk2toyin]

I need help returning 4 different values from and array containning mixed alphabets A to Z and a to z. My code looks something like this:

<?php

$mixedL = array ("A", "B", "C"......."Z", "a", "b", "c",....."Z" );

$randLet = rand($mixedL);

return $randLet;

 

?>

Create a function called getRandomLetter() or something, which:

 

1. Generates a random number, rand($min, $max).

 

2. Returns the element in the array with the generated number, like: return $mixedL[$randomizednumber]

 

Then call this function every time you need a new number.

$mixedL = array_merge(range('A','Z'), range('a', 'z'));

for ($i=0; $i<10; $i++)
{
    shuffle($mixedL);
    echo join(array_slice($mixedL,0,4)) .'<br>';
}

/*** results
OPTq
HSoh
awfI
CNKj
fjHG
Pmht
ZOWs
PzoJ
pqYz
FnfM
*/

or

 

$mixedL = array_merge(range('A','Z'), range('a', 'z'));
$x = array_rand($mixedL, 4);
foreach ($x as $ind) {
    echo $mixedL[$ind];
}

A big thank you for your reply. I will try them out right now

Thanks Barand for your reply, it was helpful. The first works great if I was to specify the numbers of results to be generated with a form. The second on the other hand doesn't output anything...why is this?

Sorry about that Barand, my mistake. Both works perfectly...thanks for the help
