class - Reassigning $this in PHP/Laravel -

-

i have class extends class b

class extends b{     function home(){         $site = new sitescontroller($this);         return $site->home();     } }

i want every variables in class availabe in sitescontroller class. dont want extend sitescontroller since everytime called re-initialized , there lot of repeated query calls. tried pass $this when class created. cant reinitialize $this in sitescontroller this.

class sitescontroller implements siteinterface {     function __construct($data) {         $this = $data;     } }

is there anyway can make work?? thanks.

you can't "reassign" $this.

but can assign instance of property of sitescontroller, means can access public methods/properties of within sitescontroller instance.

class sitescontroller implements siteinterface {     protected $a;      public function __construct(a $data) {         $this->a = $data;     }      public function dosomething() {         return $this->a->publicmethodofa();     } }

this "dependency injection", , applying principle of composition rather inheritence

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
