Answer 1

This is probably the most hackish solution I'll come up with all this morning, but if you are shooting for a quick one-liner, this should do:

if(in_array(1, array_column($myArray, 'required')))
   echo 'required';

Edit: This assumes you've got PHP 5.5+ at hand

Update: After a closer look at the documentation of in_array(), this should be possible:

if(in_array(array('required' => 1), $myArray))
    echo 'required';
