PHP基础知识之二

1 PHP中给数组中的每个值赋值 用$ages = array("Peter"=>32, "Quagmire"=>30, "Joe"=>34); 他等价于

   $ages['Peter'] = "32"; $ages['Quagmire'] = "30"; $ages['Joe'] = "34";

2 PHP多维数组 

$families = array
(
  "Griffin"=>array
  (
  "Peter",
  "Lois",
  "Megan"
  ),
  "Quagmire"=>array
  (
  "Glenn"
  ),
  "Brown"=>array
  (
  "Cleveland",
  "Loretta",
  "Junior"
  )
);
echo "Is " . $families['Griffin'][2] .
" a part of the Griffin family?";

Array
(
[Griffin] => Array
  (
  [0] => Peter
  [1] => Lois
  [2] => Megan
  )
[Quagmire] => Array
  (
  [0] => Glenn
  )
[Brown] => Array
  (
  [0] => Cleveland
  [1] => Loretta
  [2] => Junior
  )
)
