php 数组创建方法

一维数组：效果[{"id":674},{"id":675}]

$rs11="303,304";
$rs = explode(',',$rs11);  
for($i=0;$i<count($rs);$i++){ 
         $array[] = $rs[$i];
   }

echo "<pre>";

print_r($array);
echo "</pre>";

结果：

Array[1,2,4]

二维数组：效果[{"id":674,"name":"北京理工大学"},{"id":675,"name":"南开大学"}]

$rs11="303,304";
$rs = explode(',',$rs11);  
for($i=0;$i<count($rs);$i++){ 
         $array[$i]['id'] = 1;
         $array[$i]['name'] = 2;
   }

echo "<pre>";

print_r($array);
echo "</pre>";

结果：

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => 2
        )

    [1] => Array
        (
            [id] => 1
            [name] => 2
        )

)

1、创建数组

$array1[] = 10;
$array1[] =50;
echo "<pre>";
print_r($array1);
echo "</pre>";

输出结果：

Array
(
    [0] => 10
    [1] => 50
)

$array1['中大'] = 10;
$array1['清纯'] =50;
echo "<pre>";
print_r($array1);
echo "</pre>";

输出结果：

Array
(
    [中大] => 10
    [清纯] => 50
)

3、拼装数组

输出结果：

Array
(
    [北京理工大学] => Array
        (
            [val] => 120
            [items] => Array
                (
                    [val] => 1000
                    [items] => 10
                )

        )

    [中大] => 10
    [清纯] => 50
)

PHP代码：

//3三级
$array3=array();
$array3['val'] = 1000;
$array3['items'] = 10;
//二级
$array2=array();
$array2['val'] = 120;
$array2['items'] = $array3;


$array1['北京理工大学'] =$array2;
$array1['中大'] = 10;
$array1['清纯'] =50;
echo "<pre>";
print_r($array1);
echo "</pre>";
