It seems like
$this->SHXFile can also be of type false or null ; however, PhpMyAdmin\ShapeFile\ShapeFile::_saveBBox() does only seem to accept object<PhpMyAdmin\ShapeFile\file> , maybe add an additional type check?
If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /**
* @return array|string
*/
function returnsDifferentValues($x) {
if ($x) {
return 'foo';
}
return array();
}
$x = returnsDifferentValues($y);
if (is_array($x)) {
// $x is an array.
}
If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue.
