Incorrect order of suggestions

Could you please check if you have "Sort suggestions alphabetically" checkbox enabled in "Settings | Editor | General | Code Completion" settings window?

Thanks for support, this checkbox is 'off'.

I've updated to 2018.3.2, issue is still in place.

Now the order of functions in the list corresponds to order in the class. Still not suggesting automatically the closest match.

With this code:

<?php

class Foo
{
    public function convertIntegerToDecimal()
    {
    }

    public function convertDecimalToInteger()
    {
    }
}

$class = new Foo();
$class->convert

.. I get these suggestions:

convertDecimalToInteger (selected)
convertIntegerToDecimal

But as soon as I type i they get reversed. I have the factory settings:

P.S. With these settings you can also type $class->ci and get a match.

Thanks for the example. You can add this info as a comment at https://youtrack.jetbrains.com/issue/WI-42330

I've also checked the "weight" of completion results and they are pretty much the same:

weights:
convertDecimalToInteger frozen=true, sorter=1, stats=0, proximity=[openedInEditor=true, phpScope=0, phpNamespace=40, phpSameFile=true, sameDirectory=true, sameLogicalRoot=false, sameModule=2, inResolveScope=false, sdkOrLibrary=false]
convertIntegerToDecimal frozen=true, sorter=1, stats=0, proximity=[openedInEditor=true, phpScope=0, phpNamespace=40, phpSameFile=true, sameDirectory=true, sameLogicalRoot=false, sameModule=2, inResolveScope=false, sdkOrLibrary=false]
