• Get all values of a specific column in a multidimensional array 5 answers

I have this array:

Array
(
    [0] => Array
        (
            [fName] => Alice
            [lName] => Gibson
        )

    [1] => Array
        (
            [fName] => Jack
            [lName] => Smith
        )

    [2] => Array
        (
            [fName] => Bruce
            [lName] => Lee
        )

)

How to get an array with all fName values for instance:

["Alice","Jack","Bruce"]

What I've tried and worked is:

foreach($myArray as $info){
       $newArray[] = $info['fName'];      
}

question:

is it possible to use a single function instead of looping?

</div>

Answer 1

You can use array_column

array_column($array, 'fName');

array_column returns all the values in a single column with the specified key.
