This check looks for PHPDoc comments describing methods or function parameters that do not exist on the corresponding method or function.
Consider the following example. The parameter $italy is not defined by the method finale(...).
$italy
finale(...)
/** * @param array $germany * @param array $island * @param array $italy */ function finale($germany, $island) { return "2:1"; }
The most likely cause is that the parameter was removed, but the annotation was not.
protected function filterAttribute($name, $content)
$limit = isset($this->characterLimits[$name]) ? $this->characterLimits[$name] : null;
if($limit && strlen($content) > $limit)
$content = substr($content, 0, $limit - 3).'...';
return $content;
