如何在php上获取多维数组的值

Question

hi im bulding a site with php that use a json api and i need to echo the values of an multidimensional array

 "troopsLevels": [
{
  "value": 5,
  "globalID": 4000000
},
{
  "value": 5,
  "globalID": 4000001
},
{
  "value": 4,
  "globalID": 4000002
},

this is a example of my json file what i need is to show the value "value" knowing depending of the globalID

but not sure how to do it

i was thinking something like

      $troop_lvl = $data['troopsLevels'];

if($troop_lvl['globalID'] == 4000000){echo $troop_lvl['value']}

but of curse this will not work as i dont specify the item [0]..[2]

but that actually thats what i need to avoid using [0] to select specific array i need to read all and only show the ['value'] when i give the globalid

i really hope yo can understand me english is not my mother language thanks a lot for you help

Answer 1

You need to use foreach loop

foreach ($troop_lvl as $key=>$value) {
  if($value['globalID'] == 4000000) {
    echo $value['value'];
  }
}
