PHP数组之PHP基础入门教程_PHP教程

$names = array("Peter","Quagmire","Joe");

$names[0] = "Peter";
$names[1] = "Quagmire";
$names[2] = "Joe";可以在脚本中使用这些 ID 键：

$names[0] = "Peter";
$names[1] = "Quagmire";
$names[2] = "Joe";

echo $names[1] . " and " . $names[2] . " are ". $names[0] . "'s neighbors";
?>

以上代码的输出：

Quagmire and Joe are Peter's neighbors

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

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

echo "Peter is " . $ages['Peter'] . " years old.";
?>

以上脚本的输出：

Peter is 32 years old.

$families = array
(
"Griffin"=>array
(
"Peter",
"Lois",
"Megan"
),
"Quagmire"=>array
(
"Glenn"
),
"Brown"=>array
(
"Cleveland",
"Loretta",
"Junior"
)
);如果输出这个数组的话，应该类似这样：

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

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?
