How to access associative array in yii2

Question

How to access the values in associative array in yii2. Note that this array is return by the ArrayHelper. I want to access the value of project_id . I tried to use getColumn($array, 'project_id') property from the ArrayHelper class. But it throws: unidentified index project_id.

This below shown array is dumped using VarDumper of yii2:

[ 
  [ 
    [ 
 'plot_id' => '9',

 'plot_no' => '4',

 'project_id' => '1', 

 'project' =>
      [ 
   'project_id' => '1',
   'project_name' => 'City Dubaiq', 

      ],
    ], 
  ], 
]

Well you have two instances of project_id in your example, and you have not specified which one you need. Do you need all project_id values in a given array recursively? — vstm

wow. how did they manage to actually have a worse var_dump then the very correct var_dump(). you don't even see the two first [0] keys... you should try var_dump($array), you would have understood right away how to access your variable — Félix Adriyel Gagnon-Grenier

The people who designed the var dumper of yii2. If you look closely, we should be seeing a nested array in which the two first level are at key 0, however we do not see the numeric keys in their var dumper (or at least in ops code) — Félix Adriyel Gagnon-Grenier

Hi, Thanks I solved it by using ArrayHelper. First I did not use array helper instead I got results as Array(). — karanlv00012

You can get the value of project_id in Yii2's ArrayHelper like below(with your code):

echo \yii\helpers\ArrayHelper::getValue($array[0][0], 'project_id'); //1
