PHP only remove commas from numbers in this associative array?-CodePudding

What is the best method to remove commas from numbers in the associative array below? Keep the commas in text, thanks.

$main_arr contains the following 3 arrays:

Array
(
    [phrase] => Hi, I'm ok
    [number_a] => 3,575
    [number_b] => 64
    [number_c] => 8,075
)
 
Array
(
    [phrase] => Bye, it's late
    [number_a] => 7,365
    [number_b] => 32
    [number_c] => 648,120
)
 
Array
(
    [phrase] => Good catch!
    [number_a] => 11,659
    [number_b] => 128
    [number_c] => 1,492,352
