How to get random array values, not just keys with php? -

i trying create little app randomly selects number of chords/notes scale having trouble using array_rand random values array. have array called $scale looks this:

array (   [0] => f#   [1] => g#   [2] => a#   [3] => b   [4] => c#   [5] => d#   [6] => f ) 

i have array called $chord_amt:

$chord_amt = array(2,3,4,5,6); 

i have used array_rand function randomly select 1 item array so:

$selected_chord_amt = $chord_amt[array_rand($chord_amt)]; 

now want output whatever number of random chords function can produce:

$random_chords = array_rand($scale, $selected_chord_amt); 

the problem is, if print array, instead of seeing chord/note values shows keys example:

array ( [0] => 3 [1] => 4 )  

how actual values, above output this?

array ( [0] => b [1] => c# ) 

noob question, know. sorry.

i'd suggest using different approach, actually. using array_rand on array

$chord_amt = array(2,3,4,5,6); 

isn't needed generate random number between 2 , 6. php has rand function that.

consider following instead:

// shuffle list of chords shuffle($scale);  // take slice of random length between 2 , 6 $random_chords = array_slice($scale, 0, rand(2, 6));
