Issue Description

I am experiencing a problem with "Go to Definition" feature. When file has multiple function having parameter with same name, "Go to Definition" jumps to first function declaration, regardless from which function parameter we examined. Testfile:

function f1($a) {
    $a + 1;
}

function f2 {
    param($a)
    $a + 2;
}

function f3 {
    param($a)
    $a + 3;
}

Action: Right click on $a inside f3 and select "Go to Definition"
Expected result: editor caret is planced before param $a in function f3 declaration
Actual result: editor caret is planced before param $a in function f1 declaration

The result does not depend on how params are defined (param keyword vs inline declaration)

Thanks for the report! I'll take a look.

This is still happening on the latest build

Version: 1.41.1 (user setup)

In this sample the $serviceid definition is in GetStatus but the cursor jumps to the same variable in GetService (the first variable in the list)

I built a lot of new AST utility functions for the rename provider, one of which can probably fix this issue.
