Hi Laruence,

Sorry, I don't understand what you mean. The tests don't cover the case when the key is
empty.

The issue also doesn't manifest when the empty key isn't the first element i.e. this:

<?php 

class A{
    function __debugInfo(){
        return [
            
            "foo" => 'bar',
            '' => 'bar',
        ];
    }
}


print_r(new A);

?>

works fine.

or at least a expected side affect

I have to say it's expected behavior

see: https://github.com/laruence/php-src/blob/master/Zend/tests/debug_info.phpt

Description:
------------
Returning debug info through the function __debugInfo with an empty key as the key for the first
element gives a warning message "Notice: Illegal member variable name in /in/0raS3 on line
10"

Test script:
---------------
<?php

class A{
    function __debugInfo(){
        return ['' => 1];
    }
}


print_r(new A);

Expected result:
----------------
A Object
(
    [] => 1
)

Actual result:
--------------
A Object
(
    [
Notice: Illegal member variable name in /in/0raS3 on line 10
] => 1
)
