According to what I can find in the PHP (5.3.2) source code, getDocComment will return the doc comment as the parser found it.

The doc comment (T_DOC_COMMENT) must begin with a /** - that's two asterisks, not one. The comment continues until the first */. A normal multi-line comment /*...*/ (T_COMMENT) does not count as a doc comment.



The doc comment itself includes those five characters, so <?php substr($doccomment, 3, -2) ?> will get you what's inside. A call to trim() after is recommended.

If you're using a bytecode cache like eAccelerator this method will return FALSE even if there is a properly formatted Docblock. It looks like the information required by this method gets stripped out by the bytecode cache.

The code getDocComment() is not as effective as it seems, a method with a well-crafted regular expression, can solve some problems that this method does not address, for example: Some comments that begin with "/ *" will not be returned in a file too extensive.





The method below shows how you can use a regular expression to get better results.





This code snippet captures the comments in a file. "Php" and replaces it with an empty string, ie "cut" the comments of a class: 





<?php


    public function getComments() {





        $expr = "/((?:\/\*(?:[^*]|(?:\*+[^*\/]))*\*+\/)|(?:\/\/.*))/";





        $filename = $this->fileDir; //file directory


        $file = fopen($filename, "r");


        $length = filesize($filename);


        $comments = fread($file, $length);





        preg_match_all($expr, $comments, $matchs); //capture the comments





        foreach($matchs[0] as $id => $variable){


            $comments = str_replace($variable,'',$comments); // replace the scores of empty


        }


        fclose($file);


        $file = fopen($filename, "w");


        $file = fwrite($file, $comments);


    }


?>
