coder: Multi-line string in array

string-in-array.php

<?php
/**
 * @file
 *
 * Example where an array() contains a multi-line string.
 *
 * The problem here is that there seems to be no good way to include
 * a multi-line string in an array. The options are either to put the
 * entire string on oneline (which makes it illegible) or (in theory)
 * to inject whitespace into the string (which changes the content).
