php:如何在不增加计数的情况下向多维数组添加一般值

Question

我有这个…

$routes = array();
loop starts...
    $routes[]['location1'] = MyValue1
    $routes[]['location2'] = MyValue2
    $routes[]['distance'] =  MyValue3
...loop ends

我想要的是这个…

Array
(
    [0] => Array
        (
            [location1] => MyValue1
            [location2] => MyValue2
            [distance] => MyValue3
        )
    [1] => Array
        (
            [location1] => MyValue1
            [location2] => MyValue2
            [distance] => MyValue3
        )
}

但是我得到的是这个…

Array
(
    [0] => Array
        (
            [location1] => MyValue1
        )
    [1] => Array
        (
            [location2] => MyValue2
        )
    [2] => Array
        (
            [distance] => MyValue3
        )
    [3] => Array
        (
            [location1] => MyValue1
        )
    [4] => Array
        (
            [location2] => MyValue2
        )
    [5] => Array
        (
            [distance] => MyValue3
        )
}

正确的语法是什么?或者我是否需要添加一些计数器来计算循环的迭代次数使用$routes[$a]['distance']之类的东西?

Answer 1

最简单的方法是构建子数组，然后将其添加到单个赋值中:

$routes = array();
loop starts...
    $routes[] = array (
        'location1' => MyValue1,
        'location2' => MyValue2,
        'distance' =>  MyValue3
    );
...loop ends

每次对$routes[]做任何事情时，都要向$routes添加一个元素。因此，您必须执行上述操作或跟踪您正在使用的索引。

也可以这样做:

$routes=Array(
"0"=>Array
(
        'location1' => 'MyValue1',
        'location2' => 'MyValue2',
        'distance' => 'MyValue3'
),
"1"=>Array
    (
        'location1' => 'MyValue1',
        'location2' => 'MyValue2',
        'distance' => 'MyValue3'
    )
);
