$ages = array("Peter"=>32,               "Kate"=>30,               "Joe"=>34);

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

以上脚本的输出：

Peter is 32 years old.

定义数组

$families = array(  "Griffin"=>array  (  "Peter",  "Lois",  "Megan"  ),  "Quagmire"=>array  (  "Glenn"  ),  "Brown"=>array  (  "Cleveland",  "Loretta",  "Junior"  ));

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

输出上面的数组中的一个单一的值：

echo "Is " . $families['Griffin'][2] . " a part of the Griffin family?";

以上代码的输出：

Is Megan a part of the Griffin family?
