this question has answer here:

• php method chaining? 7 answers

i see in codeigniter sintaxis method->other_method->other_method_again. example:

$this->db->select()->join()->findall(); 

when try

class myclass{        public function bla(){              echo "bla";        }        public function other(){              echo "other";        } }  $message = new myclass();  $message->bla()->other(); 

return:

fatal error: call member function other() 

as can codeigniter?

this called method chaining (popularised jquery chaining) , achieved if

return $this

from each method

for example:

class myclass{        public function bla(){              echo "bla";              return $this; // enable method chaining        }        public function other(){              echo "other";              return $this; // enable method chaining        } } 

the reason works same following works:

$instance->method1(); $instance->method2(); 

here each method called on $instance but if each method returns actual $instance same $this, 1 can combine statements ("chain" them):

$instance->method1()/* returns $instance , can used again*/->method2(); 

that's there it.
