17.     #Este metodo devuelve recibe un arreglo y lo codifica en utf8 para no causar problemas en json
18.     function utf8_converter($array){
19.       array_walk_recursive($array, function(&$item, $key){
20.           if(!mb_detect_encoding($item, 'utf-8', true)){
21.                   $item = utf8_encode($item);
22.           }
23.       });
24.  
25.       return $array;
26.     }
27.   }
28. ?>
29.  

but instead of give m the array, or a string with only the db array, it returns me the whole code in an string
"<?php
class conexion{......"
