I am having array like bellow.I don't understand how it is created.
xyz Object ( [foo] => 10 [foo1:protected] => Array ( [b] => 5 [b1] => 6 ) )
my questions
What is xyz
How can i get the value of b1
How this array is created
How :protected is used in array
What is the difference between this one and normal or stdobject array
Thanks in advance
This is an instance of class xyz which contains fields : foo and foo1.
<?php
class xyz
{
var $foo=10;
protected $foo1=array("b"=>5,"b1"=>6);
public function getB1() { return $this->foo1["b1"];}
}
$a=new xyz();
print_r($a);
// print $a->foo1["b1"]; // can't be accessible due to protection
print $a->getB1();
?>
1) I believe that is the object or class name (can't remember which).
2) You can't outside of the class unless you have a public getter for the array (it's protected).
3) It's not an array, it's an object. It is initialised somewhere in your code.
4) Protected is a class access keyword, it's not used with arrays.
5) stdClass (assuming that's what you mean) wouldn't have a set var protected (somebody correct me if that's wrong).
xyzis an object, not an array. Read the manual.
