php入門教學(八) PHP數組

$user[0]=1;
$user[1]="kobe";
$user[2]=10;
$user[3]="mac";
$user[4]="kobe@bb.com";

echo '';  </li>
<li>print_r($user);  </li>
<li>echo '';

例子：关联数组

$user=array("id"=>1, "name"=>"kobe", "age"=>10, 100=>"mac", "kobe@bbb.com");

for($i=0; $i<20; $i++)
    $user[]=$i;
echo '';  </li>
<li>print_r($user);  </li>
<li>echo '';

例子：php多维数组

$User =array(
   array('张3',93),
   array('李4',80),
   array('王5',98)
   );

例子：php数组元素的遍历

//定义一个数组
$arr = array(0=>"kobe", 1=>"mac-t", 2=>"lin");
//使用第一种方法对数组进行遍历
foreach ($arr as $value) {
    echo "Value: $value; ";
}
echo "";
//使用第二种方法对数组进行遍历
foreach ($arr as $key => $value) {
    echo "Key: $key; Value: $value; ";
}
?>

2）、

//定义数组
$array = array("ar1" => array(5=>100, 3=>120, 4=>30),
"ar2" => array(4=>"three", 9=>"four", 1=>"five"));
//对数组进行遍历
foreach ($array as $v1)
{  // bbs.it-home.org
    foreach ($v1 as $v2)
    {
        print "$v2/n";
    }
}
?>
