PHP Random collection of element from an array

$value=array("Rabin","Reid","Cris","KVJ","John");


$rand_keys=array_rand($value,2);
echo "First random element = ".$value[$rand_keys[0]];
echo "<br>Second
random element = ".$value[$rand_keys[1]];

srand ((double) microtime() * 10000000);
$input = array ("A", "B", "C", "D", "E","F","G","H","I","J","K","L","M","N","O","P","Q",
"R","S","T","U","V","W","X","Y","Z");
$rand_index = array_rand($input,6);
print $input[$rand_index[3]];
print $input[$rand_index[5]];
print $input[$rand_index[4]];
print $input[$rand_index[2]];
print $input[$rand_index[1]];
print $input[$rand_index[0]];

Example 1: Selecting One Random Element

<?php
$names = array("Alice", "Bob", "Charlie", "David");
$random_key = array_rand($names);
echo $names[$random_key];  // Outputs a random name
?>

Example 2: Selecting Multiple Random Elements

<?php
$names = array("Alice", "Bob", "Charlie", "David");
$random_keys = array_rand($names, 2);
echo $names[$random_keys[0]] . ", " . $names[$random_keys[1]];  // Outputs two random names
?>

Example 3: Randomly Selecting Keys from an Associative Array

<?php
$fruits = array("a" => "Apple", "b" => "Banana", "c" => "Cherry");
$random_key = array_rand($fruits);
echo "$random_key => " . $fruits[$random_key];  // Outputs a random key and value
?>

Example 4: Selecting Multiple Keys and Displaying Keys and Values

<?php
$fruits = array("a" => "Apple", "b" => "Banana", "c" => "Cherry");
$random_keys = array_rand($fruits, 2);
foreach ($random_keys as $key) {
    echo "$key => " . $fruits[$key] . "<br>";
}
?>
