php foreach循环多维数组有问题

I'm having problems getting values in my multidimensional arrays

我无法在多维数组中获取值

Array
(
    [0] => Array
        (
            [name] => Brandow & Johnston, Inc.
            [lat] => 34.051405
            [lng] => -118.255576
        )

    [1] => Array
        (
            [name] => Industry Metrolink Train Station
            [lat] => 34.00848564346
            [lng] => -117.84509444967
        )

    [2] => Array
        (
            [name] => The Back Abbey
            [lat] => 34.095161
            [lng] => -117.720638
        )

    [3] => Array
        (
            [name] => Eureka! Burger Claremont
            [lat] => 34.094572563643
            [lng] => -117.72184828904
        )

)

Lets say I have an array such above

假设我有一个这样的数组。

And I'm using a foreach loop such as below

下面我用的是foreach循环

foreach($_SESSION['array'] as $value){

    foreach($valueas $key_location=> $value_location){

        if($key_location = "name"){$fsq_name = $value_location;}
        $fsq_lat = $value_location["lat"];
        $fsq_lng = $value_location["lng"];



        echo "<i>".$fsq_lat."</i><br/>";

        }

    }

I've tried using the if statement, or using $value_location["lat"]; but its not producing the correct values.

我尝试过使用if语句，或者使用$value_location["lat"];但它并没有产生正确的价值。

If I do if($key_location === "lng"){$fsq_lng = $value_location;} with three equal signs, it'll give me errors for a few iterations and then produce the lng results. if I just do one equal sign and echo it out, it'll give me the name key as well.

如果我这样做($key_location === "lng"){$fsq_lng = $value_location;}有三个相等的符号，它会在几次迭代中给我错误，然后产生lng结果。如果我做一个等号，并把它重复出来，它也会给我命名键。

Am I missing something?

我遗漏了什么东西?

Thanks

谢谢

You don't actually need the inner foreach loop. The outer one is sufficient, since it iterates over arrays. The inner arrays can be accessed by key inside the outer foreach.

实际上并不需要每个循环的内部。外部的是充分的，因为它遍历数组。内部数组可以通过键在外部foreach中访问。

foreach($_SESSION['array'] as $value){
  $fsq_name = $value["name"];
  $fsq_lat = $value["lat"];
  $fsq_lng = $value["lng"];

  echo "<i>".$fsq_lat."</i><br/>";

  // Actually none of the above assignments are necessary
  // you can just:
  echo "<i>".$value["lat"]."</i><br/>";
}

Maybe refactor a bit?

也许重构一点?

foreach($_SESSION['array'] as $value)
{
    // pull the lat and lng values from the value
    $fsq_lat = $value["lat"];
    $fsq_lng = $value["lng"];
    $fsq_name = $value["name"];

echo "<i>".$fsq_lat."</i><br/>";


}// foreach
