Hi,
when i extend a class containing a private variable and then access the variable in the extended class it doesn't produce any error and works fine and when i access the variable using the object of the extended class it works even then, i think private variable should not be accessable in an extended class neither by object of that extended class
here is the code
<?php
class textbox{
var $body_text, $body_text1;
private $body_private="this is private value";
protected $body_protect="this is protected value";
function __construct($text_in, $text_out){
$this->body_text=$text_in;
$this->body_text1=$text_out;
}
function display(){
echo "$this->body_text<br>";
echo "<i>";
echo "$this->body_text1</i><br>";
echo "$this->body_private<br/>";
echo "$this->body_protect<br/>";
}
function test_new(){
echo "see if this private echo works";
}
}
$box=new textbox("any new value","any old value" );
$box->display();
$box->body_text="this is public thats why i can access it";
$box->body_text1="this is public thats why i can access it";
/*$box->body_private="this is private value changed"; //you will see we can't access the private and protected memebers from outside
$box->body_protect="this is protected value changed"; */
$box->display();
$box->test_new();
class textboxbold extends textbox{
function __construct($text_on, $text_off, $text_get, $text_go)
{$this->body_text=$text_on;
$this->body_text1=$text_off;
$this->body_protect=$text_get;
$this->body_private=$text_go;
}
function display(){
echo "<b>$this->body_text</b><br>";
echo "<b>$this->body_text1</b><br>";
echo "<b>$this->body_protect</b><br>";
echo "<i>$this->body_private</i><br>";
}
}
$boxnew=new textboxbold("new Bold text", "text in bold","protected member","private");
$boxnew->display();
$boxnew->body_private="this is simple text taken from outside";
$boxnew->display();
$boxnew->test_new();
?>
please recommend, is it working as it should be
