Gets doc comments from a class. Doc comments start with /**, followed by whitespace.
If there are multiple doc comments above the class definition,
the one closest to the class will be taken.
Example #1 ReflectionClass::getDocComment() example
<?php
/**
* A test class
*
* @param foo bar
* @return baz
*/
class TestClass { }
$rc = new ReflectionClass('TestClass');
var_dump($rc->getDocComment());
?>
The above example will output:
string(60) "/**
* A test class
*
* @param foo bar
* @return baz
*/"
