If a variable is not always an object, we recommend to add an additional type check to ensure your method call is safe:
function someFunction(A $objectMaybe = null) { if ($objectMaybe instanceof A) { $objectMaybe->doSomething(); } }
if (true === $required) {
$labelContent = sprintf(
'%s<span class="required-mark">*</span>',
$labelContent
);
}
return $this->openTag() . $labelContent . $this->closeTag();
