PHP创建数组

array创建一个数组！

查看数组内容：var_dump(数组变量);

一维数组：

<?php $ywsz=array(1,2,3,4);?>

输出：

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
)

多维数组:

<?php
$fruits = array (
    "xx"  => array("name" => "xiaoming", "shengao" => "165cm", "nianling" => "17"),
    "numbers" => array(1, 2, 3, 4, 5, 6),
    "chengji"   => array("shuxue"=>"100", "yuwen" => "99", "yingyu"=>"0")
);
?>

输出结果：

array(3) { 
 ["xx"]=> array(3) {["name"]=> string(8) "xiaoming" ["shengao"]=> string(5) "165cm" ["nianling"]=> string(2) "17" }
 ["numbers"]=> array(6) { [0]=> int(1) [1]=> int(2) [2]=> int(3) [3]=> int(4) [4]=> int(5) [5]=> int(6) }
 ["chengji"]=> array(3) { ["shuxue"]=> string(3) "100" ["yuwen"]=> string(2) "99" ["yingyu"]=> string(1) "0" }
 }
