PHP takes array random number

$a =array ([0] = = Array ([0] = 8 [Face_amount] = 8) [1] = = Array ([0] = [Face_amount] = 30) [ 2] = = Array ([0] = [Face_amount] = [3] = = Array ([0] = [Face_amount] = 50));//Remove from Database of data

A two-dimensional array takes a value

$b = (Array_rand ($a, 1));

echo $a [$b] [' Face_amount '];

Two-dimensional arrays take multiple values

$c = (Array_rand ($a, 2));

echo $a [$c [0]][' Face_amount '];

echo $a [$c [1]][' Face_amount '];

Define a two-dimensional array

$a =array (

Array ("Volvo", 22,18),

Array ("BMW", 25,13),

Array ("Saab", 5,2),

Array ("Land Rover", 17,15)

);

Get a

$b = (Array_rand ($a, 1));

Var_dump ($a [$b][0]);

Get multiple

$b = (Array_rand ($a, 2));

Var_dump ($a [$b [0]][0]);

Var_dump ($a [$b [1]][1]);
