复制代码 代码如下:

<?php

$array = array("key1" => "Simon", 2 => "Elaine"); //数组的创建

echo $array["key1"]; //输出Simon

echo $array[2]; //输出Elaine

?>

复制代码 代码如下:

<?php

$array = array("key1" => array(0 => 1, 1 => 10, 2 => 100),

"key2" => array(0 => 5, 1 => 25, 2 => 125));

echo $array["key1"][0]; //输出1

echo $array["key1"][1]; //输出10

echo $array["key1"][2]; //输出100

echo $array["key2"][0]; //输出5

echo $array["key2"][1]; //输出25

echo $array["key2"][2]; //输出125

?>

复制代码 代码如下:

<?php

$array = array("key1" => array(0 => 1, 1 => 10, 2 => 100), //定义数组

"key2" => array(0 => 5, 1 => 25, 2 => 125));

print_r($array); //输出数组

?>

复制代码 代码如下:

<?php

$array = array("a", "b","c"); //定义数组

print_r($array); //输出数组

?>

复制代码 代码如下:

<?php

$array = array("a", "b","c"); //定义数组

$array[0] = "Simon"; //修改数组元素

print_r($array); //输出数组
