Bug#925068: doxygen: search.php uses <script language="php"> which is not supported by php7.0





Package: doxygen
Version: 1.8.13-4+b1
Severity: important

Dear Maintainer,

The generated documentation comes with a PHP based search system. The
search.php page has:

	<script language="php">
	require_once "search_functions.php";
	main();
	</script>

However PHP 7.0 has removed support for <script language="php">:

https://php.net/manual/en/language.basic-syntax.phptags.php

Changelog

7.0.0 | The ASP tags <%, %>, <%=, and the script tag <script
      | language="php"> are removed from PHP.


As a result, the Doxygen generated documentation lacks a working search
engine.

PHP 7.0 support has been added upstream via 22b6783 and has been
released with Doxygen 1.8.15:
https://github.com/doxygen/doxygen/commit/22b67836d678cea695b977ec648c0aa013339c55
https://github.com/doxygen/doxygen/pull/680

Since Debian Stretch comes with PHP 7.0, I guess that upstream fix has
to be backported to restore the search functionality.
