Special PHP Comments

[The Titan]

I have been looking around on phpclasses.org and i have been seeing a lot of comments like this one



/**
* Constructor. Initializes a database connection and selects our database.
*
* @param string Database host
* @param string Database username
* @param string Database password
* @param string Database name
* @return boolean
*/


I was wondering if there is anything "special" about these comments or are they just a common way of describing things and where can i learn more about them.

a lot of times the comments are standardized so that you can run a program on the files and it can easily make and API that describes each function and its parameters.

like PHPdoc or something like that? Is there alike a syntax to these?
