如何将数组数组合并到一个php中

Question

I have the following array.

 Array
    (
        [0] => Array
            (
                [title] => IT Software - Application Programming, Maintenance 
            )

        [1] => Array
            (
                [title] => IT Software - eCommerce, Internet Technologies 
            )

        [2] => Array
            (
                [title] => IT Software - Client/ Server Programming
            )

        [3] => Array
            (
                [title] => IT Software - Other 
            )

    )

Would like to get the resultant array as below

Array
(
    [0] => IT Software - Application Programming, Maintenance

    [1] => IT Software - eCommerce, Internet Technologies 

    [2] => IT Software - Client/ Server Programming

    [3] => IT Software - Other 


)

can i get a simple one liner other than array_column() because im running php version below 5.5. I tried $funcmerged = array_reduce($functionalres, 'array_merge', array()); but iam not getting desired result.

Found a pretty good solution

How to Flatten a Multidimensional Array?

function flatten(array $array) {
        $return = array();
        array_walk_recursive($array, function($a) use (&$return) { $return[] = $a; });
        return $return;
    }

Hope it helps.
