undefined == null
So, there's no need to write:
if ( firstVar === undefined || firstVar === null) { // your code }This works just the same:
firstVar === undefined || firstVar === null)
undefined == null
if ( firstVar === undefined || firstVar === null) { // your code }This works just the same:
firstVar === undefined || firstVar === null)

Lazy load proxies always contain an instance of Doctrine’s EntityManager and all its dependencies. Therefore a var_dump() will possibly dump a very large recursive structure which is impossible to render and read. You have to use Doctrine\Common\Util\Debug::dump() to restrict the dumping to a human readable level. Additionally you should be aware that dumping the EntityManager to a Browser may take several minutes, and the Debug::dump() method just ignores any occurrences of it in Proxy instances.src: http://www.doctrine-project.org/docs/orm/2.1/en/tutorials/getting-started-xml-edition.html
