Another useful property of traits:
<?php
namespace Traits;
trait Properties{
public function __get($var){
$var = '_' . $var;
$getter = '_get' . $var;
if(method_exists($this, $getter)){
try{
$val = $this->$getter();
}catch(\Exception $e){
throw new \Exception($e);
}
return $val;
}
throw new \Exception('Can not get property: ' . $var . ', method ' . $getter .
' not exists');
}
public function __set($var, $val){
$var = '_' . $var;
$setter = '_set' . $var;
if(method_exists($this->$setter) && isset($this->$var)){
try{
$setval = $this->$setter($val);
}catch(\Exception $e){
throw new \Exception($e);
}
$this->$var = ($setval === NULL) ? $this->$var : $setval;
}else{
throw new \Exception('Can not set property: ' . $var . ', method ' . $setter
. ' not exists');
}
}
}
class Some{
use \Chidori\Traits\Properties;
// Magic begin
protected $_var = 42;
protected function _get_var(){ return $this->_var; }
protected function _set_var($val){ return NULL; }
}
$s = new Some();
$s->var = 23; \\ set value
echo $s->var; \\ return 42? where is my 23? =)
