chunk_split

  • Splitting a long string into smaller chunks can be done in Ruby using a sequence of:

    1. String#scan the string into the specified chunk size
    2. Array#join the string back together using the ending sequence as the glue
    3. String#+ appends the final ending sequence to the result

    PHP

    $result = chunk_split("a really long string", 5, "\r\n");
var_export($result);
// => "a rea\r\nlly l\r\nong s\r\ntring\r\n"

    Ruby

    p "a really long string".scan(/.{1,5}/).join("\r\n") + "\r\n"
# => "a rea\r\nlly l\r\nong s\r\ntring\r\n"
