Answer 11

Twig, 105 bytes

This uses a simple replacement to fill in the gaps.

Twig's replace() filter allows you to define the values to replace as the keys of an hash. Luckly, it also works with arrays, as they have numerical keys.

{{"0a1.
A1 0.
If 0 a1,
Where's the1 0?"|replace(["Peter Piper picked"," peck of pickled peppers"])|raw}}

The |raw is needed to avoid escaping, which turned Where's into Where's.

You can try it on https://twigfiddle.com/phqpts

---

Since this is compiled down to PHP, the equivalent for PHP would be:

<?php
    $array = array("Peter Piper picked", " peck of pickled peppers");
    $string = "0 a1.
A1 0.
If 0 a1,
Where's the1 0?";

    echo str_replace(array_keys($array), $array, $string);

Which can be shortened significatively.

The job is done by the rejoin funcion, which reduces and joins a block of values.

Self-extracting Cabinet file using Batch/CAB polyglot. The blank line is needed for the batch file processor to find the actual batch code, but can be LF alone instead of CR/LF. The Cabinet file is just a series of "@echo <string>" lines, and the '@' symbol suppresses the "echo" itself from being displayed.

Answer 34

Alternatively,

set a= Peter Piper picked
set b= peck of pickled peppers
@echo%a% a%b%.
@echo A%b%%a%.
@echo If%a% a%b%,
@echo Where's the%b%%a%?

Using LF alone instead of CR/LF combinations for line-endings.
