see blow, and I think you will find out the reason:
<?php
class Example{
private $p1;
function __construct($a){
$this->p1=$a;
}
function __get($elmname){
echo "Call_get()!"; //In order to follow the method __get()
}
function __unset($name){
unset($this->$name);
}
}
$example = new Example("v1");
unset($example->p1);
echo $example->p1;

Description:
------------
<?php
class Example{
private $p1;
private $p2;
function __construct($a){
$this->p1=$a;
}
function __get($elmname){
echo "Call_get()!"; //In order to follow the method __get()
return $this->$elmname;
}
function __isset($name){
return isset($this->$name);
}
function __unset($name){
unset($this->$name);
}
}
$example=new Example("v1","v2");
echo $example->p1."<br/>";
var_dump(isset($example->p2));//p2 is uninitialized,the result is bool(false)
echo $example->p2;//This time,__get is called by 1 time.
unset($example->p1);
var_dump(isset($example->p1));//Because of __unset,the result is bool(false)
echo $example->p1;//Amazingï¼I call the __get just once,but it seems that the
__get method has bean called two times!
?>
Expected result:
----------------
Call_get()! v1
bool(false) Call_get()ï¼bool(false) Call_get()ï¼
Actual result:
--------------
Call_get()! v1
bool(false) Call_get()ï¼bool(false) Call_get()ï¼Call_get()ï¼
