How to get value for a certain key in multidimentionnal php array?

A certain php array give me this :

myarray{
    0=>array { "key_01"=>"value_01", "key_02"=>"value_02"..."key_0n"=>"value_0n"}
    1=>array { "key_11"=>"value_11", "key_12"=>"value_12"..."key_1n"=>"value_1n"}
    .
    .
    .
    n=>array { "key_n1"=>"value_n1", "key_n2"=>"value_n2"..."key_nn"=>"value_nn"}
}

And i would like to get this one array:

$newarray = {value_01,value_11,value_n1......value_nn}

// Loop through your original array
foreach($myarray as $array){
   // ensures that the keys are in alphabetical/numerical order
   ksort($array);

   // add the first value into your new array
   $newarray[] = reset($array);
}

You can use array_map to get what you want on each item of your array :

$array = array_map(function ($item) { return current($item); }, $array);

In your case, this seems to be the first value of the item, so you use current.

You can get the first value of each sub-array with current or reset:

$newarray = array_map('current', $array);

If you need a certain offset (in this case the first) then get the values from each array re-indexed with integers and then extract column 0:

$newarray = array_column(array_map('array_values', $array), 0);
