# HTML processing instructions
PHP processing instruction:
<?php echo 'hello'; ?>
XML processing instruction:
<?xml version="1.0" encoding="UTF-8"?>
Multi-line PI with blank line inside:
<?php
echo '>';
?>
PI with embedded `?` chars (only `?>` closes):
<?php is ? a single char until?>
PI with markdown-looking body (stays literal):
<?php
*not emphasis*
`not code`
?>
PI followed by paragraph:
<?php
echo 'x';
?>
This is now a paragraph.
Mid-paragraph PI is inline raw HTML:
The instruction <?php echo $a; ?> is preserved.
