- $user[0]=1;
- $user[1]="kobe";
- $user[2]=10;
- $user[3]="mac";
- $user[4]="kobe@bb.com";
-
- echo '
'; - print_r($user);
- 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 '
'; - print_r($user);
- 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";
- }
- }
- ?>
