PhpStorm type hinting array of objects fails after testing with is
I am having trouble getting Phpstorm type hints working on arrays of objects when I test the array with is_array() before iterating over the array.
Can anyone shed some light on why is_array() removes the type hinting of the objects?
$test = new Test();
$testers = $test->getAll();
// Type hinting WORKS for $test
foreach($testers as $test) {
$test->getId(); // Type hinting works
}
// Type hinting does NOT work for $test
if(is_array($testers)) {
foreach($testers as $test) {
$test->getId(); // Type hinting does NOT work
}
}
I can get type hinting to work if I add type hint comment where the array is retrieved, but this is undesirable, as I would prefer Phpstorm to use the object method return type hint info instead of having to specify it all the time:
Adding this works even when is_array is present /** @var Tester[] $testers */ $testers = $test->getAll();
Test class code in case anyone wants to run the example:
class Tester {
private $id;
private $name;
public function __construct($id, $name) {
$this->id = $id;
$this->name = $name;
}
/**
* @return Integer
*/
public function getId() {
return $this->id;
}
/**
* @return String
*/
public function getName() {
return $this->name;
}
}
class Test {
/**
* @return tester[]
*/
public function getAll() {
$testers = array(
new Tester(1, 'Bob'),
new Tester(2, 'Jane'),
new Tester(3, 'Tim')
);
return $testers;
}
}
