Question

How can I convert this string to have a space every 8th digit using PHP or Shell. From this:

0100010101110010011100100110111101110010

To this:

01000101 01110010 01110010 01101111 01110010

Answer 1

The far fastest and also clearest method to solve that is most likely the following:

<?php
 $input = "0100010101110010011100100110111101110010";

 $newString = chunk_split($input, 8, ' ');
 echo $newString;

?>
