           Summary: function type hinting is wrong with boolean
                    expressions
    Classification: Unclassified
                OS: Linux
          Reporter: tim.climis@gmail.com

This is sort of related to Bug 257465.  When you hover over a function in PHP,
it attempts to guess the return type and parameter types of the function.  For
the most part it does a pretty good job, but there's an oddity with booleans.

For example, if you use this code, it will correctly guess that the function
returns a boolean:
function foo() {
    $success = true;
    return $success;
}

But, if you instead do this, it will guess that the function returns an
integer.
function bar() {
    $success = (strlen('blah') > 0);
    return $success;
}

At first I thought that perhaps this a was a quirk of PHP - that comparisons
actually returned 0 or 1, rather than true or false values.  But looking at the
PHP documentation, that does not seem to be the case, so I think it's a bug in
KDevelop.

Reproducible: Always
