arrays - Using php, how to get return object data into variable? -

i have read number of answers on not getting something. have object retrieves data file , puts array format , trying data variable in calling file can work data.

 calling.php      $x = new obj();     $x -> method_y();   objectfile.php      public function method_y(){        ..... code stuff .....        print_r($array);     }      array(          [0] => array              (                  [key1] => value1                  [key2] => value2                  [key3] => value3              )           [1] => array              (                  [key1] => value1                  [key2] => value2                  [key3] => value3               )     ) 

is better use echo, return, or print method , should use json_encode return it. how returned data out of object can work with. instance using json_encode in method json json_decode wants string.

again have read number of answers on not getting it.

thanks in advance.

you can return array itself, , traverse array using loops, maybe this

public function method_y(){     ..... code stuff .....     return $array; }  $var = $x -> method_y();  foreach($var $element) {     foreach($element $key => $value) {           echo $key;           echo $value;     } }
