Question

So I am not sure exactly what I would have to show you guys  how ever if you need more code please do not hesitate to ask   So this method will set up the initMailer for Zend with in our application   protected function  initMailer         if   testing       APPLICATION ENV             this- gt bootstrap  Config             options    this- gt getOptions             mail   new Zend Application Resource Mail  options  mail          elseif   testing        APPLICATION ENV              change the mail transport only if dev or test         if  APPLICATION ENV  lt  gt   production                   callback   function                                 return  ZendMail     microtime true     tmp                                mail   new Zend Mail Transport File                  array  path    gt    tmp mail                             callback   gt  callback                                               Zend Mail  setDefaultTransport  mail                         return  mail      You can see the closure that lies with in  When I run any tests that use this code I get   Exception  Serialization of  Closure  is not allowed    and thus all the tests in relation to this  closure  fails  So I am here asking you guys what I should do   For clarification on the above  all were doing is saying that any email we send out we want to store information about that email in a folder in the  tmp mail  directory in a file

Direct Closure serialisation is not allowed by PHP. But you can use powefull class like PHP Super Closure : https://github.com/jeremeamia/super_closure

This class is really simple to use and is bundled into the laravel framework for the queue manager.

From the github documentation :

$helloWorld = new SerializableClosure(function ($name = 'World') use ($greeting) {
    echo "{$greeting}, {$name}!\n";
});

$serialized = serialize($helloWorld);

Apparently anonymous functions cannot be serialized   Example    function   function          return  ABC      serialize  function      would throw error   From your code you are using Closure    callback   function        lt ---------------------- Issue       return  ZendMail     microtime true      tmp        Solution 1   Replace with a normal function  Example   function emailCallback         return  ZendMail     microtime true      tmp      callback    emailCallback      Solution 2   Indirect method call by array variable  If you look at   http   docs mnkras com libraries 23rdparty 2 zend 2 mail 2 transport 2file 8php source html     public function   construct  options   null     63          64         if   options instanceof Zend Config       65              options    options- gt toArray       66           elseif   is array  options        67              options   array       68              69     70            Making sure we have some defaults to work with    71         if   isset  options  path          72              options  path     sys get temp dir       73              74         if   isset  options  callback          75              options  callback     array  this   defaultCallback     lt - here    76              77     78          this- gt setOptions  options      79         You can use the same approach to send the callback    callback   array  this  aMethodInYourClass

As already stated  closures  out of the box  cannot be serialized    However  using the   sleep      wakeup   magic methods and reflection u CAN manually make closures serializable  For more details see extending-php-5-3-closures-with-serialization-and-reflection  This makes use of reflection and the php function eval  Do note this opens up the possibility of CODE injection  so please take notice of WHAT you are serializing
