Question

I want to split a word or small sentence into an array so that each letter is part of the array, but I also want to add a character in between each letter then output it back into a string.
The character I want to use is a Unicode character, U+0336 combining long stroke overlay or ” ̶ “.

Answer 1

Untested but something like:

$str = "I am a test string";
$chars = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);
$dash_separated = implode("-", $chars);
