## Look ma, I'm not targeting parameter with Attribute::TARGET_PARAMETER
final class TargetTestPropertyAttribute

final class TargetTest

    public function __construct(

}

$ref = new ReflectionClass(TargetTest::class);
$testAsProperty = $ref->getProperty('test');
$testAsParemter = $ref->getConstructor()->getParameters()[0];

// Property
echo $testAsProperty->getAttributes()[0]->getTarget() === Attribute::TARGET_PROPERTY ? "Attribute targets property\n" : "Attribute does not target property\n";

// Parameter
echo $testAsParemter->getAttributes()[0]->getTarget() === Attribute::TARGET_PARAMETER ? "Attribute targets parameter (why?)\n" : "Attribute does not target parameter\n";

Output for git.master_jit, git.master: Attribute targets property Attribute targets parameter (why?)
