An example source file showing PHP code that Doxygen doesn't parse.

When Doxygen is given a PHP source file, it recognizes PHP source code between
"<?php ... ?>" tags, but ignores code between "<script language='php'> ...
</script>" tags.

Steps to reproduce:
1. In an empty directory, create this file (minus the line numbers) as
"test.php":
     1    #!/usr/bin/env php
     2    <script language="php">
     3    /**
     4     * @brief A test class for PHP Doxygen support.
     5     */
     6    class TestClass {
     7        /**
     8         * @brief The constructor.
     9         */
    10        public function __construct() { }
    11    };
    12    </script>
2. Run Doxygen:
    doxygen -g Doxyfile
    doxygen Doxyfile
3. View the generated html/index.html

Desired results:
Doxygen should produce a "Classes" tab in the HTML documentation, which when
clicked would show the documentation for "TestClass".

Actual results:
The class documentation is not present, presumably because the <script...> tag
was interpreted as HTML output rather than parsed as PHP source delimiters.  If
line 2 is changed to "<?php" and line 12 is changed to "?>", the documentation
is produced.
