Get Random Values From Array IN PHP

I am sharing my example code to get random values from PHP array. May this small code can be helpful for someone.

// array

$arr_subjects = array('Science', 'Maths', 'GK', 'Law', 'History', 'Arts', 'Chemistry',

    'Computers', 'Bio', 'Music');

// random number

$c = rand(1, 6);

//shuffle array elements

shuffle($arr_subjects);

//print random values in an array

print_r(array_slice($arr_subjects, $c, $c));

// prints $c'th elements from $c'th position in an array
