PHP Documentation Provider

Hi all,

I am trying to build a plugin with documentation provider for a specific PHP function. This php function has different inline doc where it is used in the user code for different function parameters. For example:


function func($arg1, $arg2) {
     //
}


/**
* Inline doc for foo
*
* @param int total count
*/
func('foo', 'call_back');

/**
* Inline doc for bar
*
* @param string name
*/
func('bar', 'call_back2');


another function:

function do_func($arg1) {
//
}

Now, when the user types do_func('foo'), and click ctrl-Q for "do_func", how can IntelliJ displays inline doc for "func('foo'", instead of the doc for do_func function itself?
The official PHP plugin will generate the doc for do_func, and if I try to provide my DocumentationProvider, it is not called by IntelliJ because the official PHP documentation provider is called first, and it provides the doc.

How do I make sure my documentation provider is called first? Or is there any other way to achieve displaying the inline doc of "func"?
