An Issue with automatic code documentation | PHP - documentation

Question

I'm having a CodeIgniter project with lots of modules and codes residing in it.
Now I would like to create documentation for other new co-workers.
For example
/**
* inline tags demonstration
*
* This class generates bars using the main algorithm, which also
* works heavily with {#link foo()} to rule the world. If I want
* to use the characters "{#link" in a docblock, I just use "{#}link." If
* I want the characters "{#*}" I use "{#}*}"
*
* #author ahobbit
* #copyright middleearth.org XVII
* #version 1.2.3
*/
class bar
{
// beginning of docblock template area
/**##+
* #access private
* #var string
*/
var $_var1 = 'hello';
var $_var2 = 'my';
var $_var3 = 'name';
var $_var4 = 'is';
var $_var5 = 'Bob';
var $_var6 = 'and';
var $_var7 = 'I';
/**
* Two words
*/
var $_var8 = 'like strings';
/**##-*/
var $publicvar = 'Lookee me!';
}
/**
* Makes chocolate bars
*
* There are two aspects to this class.
* {#inheritdoc } In addition, the foo class
* makes the bars chocolate
*/
class foo extends bar
{
/**
* Check if a Sql row exists. (with two values)
*
* This function will check if a selected sql row exists that contains two
* known values.
*
* #param string $tblname Sql Table Name
* #param string $colname Sql Column Name 1
* #param string $value Sql value 1
* #param string $colname2 Sql Column Name 2
* #param string $value2 Sql value 2
* #return boolean returns true if the sql row does exist
*/
function tableHasRow2D($tblname, $colname, $value, $colname2, $value2) {
$row = sqlQuery("SELECT COUNT(*) AS count FROM $tblname WHERE " . "$colname
LIKE '$value' AND $colname2 LIKE '$value2'");
return $row['count'] ? true : false;
}
}
I had made use of with the following commands
I. PHPdoc
E:\xampp\htdocs\CI_Proj> php phpDocumentor.phar -d application

Is it be possible to add comments to the modules before or after generation of code?
Since I'm looking to add comments to specific modules in the document itself and optionally that would
automatically inserted to the source code, at the right positions.
How should I need to manage the modules and code inside the project and How would I create a browsable HTML-Documentation?
Any other tool that makes generating the documentation directly from your PHP source code, that would be great in advice
