You can use it to embed arbitrary embeded languages or "macros":
<?php
$id = 10;
// SQL
ob_start(); ?>
SELECT * FROM users WHERE parentid > $id
AND name LIKE '%s%'
<?php $f=ob_get_contents();ob_end_clean();$sql=eval('return ("'
.$f.'");');
echo $sql;
?>
Outputs:
SELECT * FROM users WHERE parentid > 10 AND name LIKE '%s%'
