How to create an array using php with identical values but different id without using loop

Question

this question is for ask if there is any better way to create an array with values like that

array(
    [0] => 'course_25_expires',
    [1] => 'course_31_expires',
    [2] => 'course_43_expires',
    [3] => 'course_45_expires',
    [4] => 'course_48_expires',
    [5] => 'course_67_expires'
)

by just using another array that can have only the IDs for that records as the one that following:

array(
    [0] => 25,
    [1] => 31,
    [2] => 43,
    [3] => 45,
    [4] => 48,
    [5] => 67
)

is there any kind of walker in PHP that can use a kind of "string template" and an array with values and produce an array with mix of the values and the template ?

You can use array_map() and an anonymous function to do this:

$output = array_map(
    function ($item) { return "course_{$item}_expires"; },
    $data
);
