Here is an example how to make it neatly and this can be made quite
dynamic by chancing the function to use for remapping the cell content:

<?php

function filterNumbers($str) {
return str_replace('-', '', $str);
}

$oldArray=array('1234-1234', '2345-2345', 'ABCD.FGHI', '3456.3456',
'-0987-0987');

$newArray=array_map('filterNumbers', $oldArray);

var_dump($newArray);

?>

The filterNumbers do the actual work (you can make it a lot more
advanced, depending on your needs).

then you input the remapping function and the original array as
arguments and you then get a modified array back.

If you want to remove items in an array, then use the array_filter(),
the argument order is different and the function needs to return true or
false.
