Relatively new to Linux but I'm trying to solve a problem.
I'm trying to make a cryptogram solver script where I use tr to easily replace the "cryptic" letters with the solved letters. I have the cryptogram as an all-lowercase text file crypt.txt. When I make replacements, the replacement letters will be uppercase to distinguish them.
My problem is that I also want those letters to change color.
I took this code from a different post I found from a search on these forums:
and edited it for my use. My general format for letter replacing say, a "k" with an "L", is:
but this only works if the letter is by itself e.g. not in the middle of a word. I've tried adding * to each side of L but was unsuccessful.
Any help would be appreciated! Thanks. This is my first post so hello everyone

Example #1
A ctype_upper(3) example (using the default locale)
<?php
$strings = array('AKLWC139', 'LMNSDO', 'akwSKWsm');
foreach ($strings as $testcase) {
if (ctype_upper($testcase)) {

";
} else {
