PHP Random collection of element from an array

We can randomly collect one or more element from an array by using array_rand() function in PHP. We can specify the number of random elements required by specifying an optional parameter in side the function. $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]]; We can create a six digit random number generator which will give us only characters.
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]];
By using above code we can generate 6 digit random number of only characters. You can read how to generate random numbers here.
