<div class="codetitle"><a style="CURSOR: pointer" data="1133" class="copybut" id="copybut1133" onclick="doCopy('code1133')"> 代码如下:

<div class="codebody" id="code1133">
<?PHP
$array = array("key1" => "Simon",2 => "Elaine"); //数组的创建
echo $array["key1"]; //输出Simon
echo $array[2]; //输出Elaine
?>

<div class="codetitle"><a style="CURSOR: pointer" data="92847" class="copybut" id="copybut92847" onclick="doCopy('code92847')"> 代码如下:

<div class="codebody" id="code92847">
<?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

<div class="codetitle"><a style="CURSOR: pointer" data="70821" class="copybut" id="copybut70821" onclick="doCopy('code70821')"> 代码如下:

<div class="codebody" id="code70821">
<?PHP
$array = array("key1" => array(0 => 1,//定义数组
"key2" => array(0 => 5,2 => 125));
print_r($array); //输出数组
