<? Php $ switching = array (10, // key = 0 5 => 6, 3 => 7, 'a' => 4, 11, // key = 6 (the maximum value of the integer key index in the entire array is 5) '8' => 2, // key = 8 (string Jian '8' is converted to 8) '02' => 77, // key = '02' (note not 2) 0 => 12/* the key with the first face value of 10 is assigned 0, the value of the 0 key is redefined as 12, which overwrites the default 0 key value */); // empty array $ empty = array ();?>

If printed using print_r ($ switching), the result is:

Array ([0] => 12 [5] => 6 [3] => 7 [a] => 4 [6] => 11 [8] => 2 [02] => 77)
