After cleaning up the code (I think the mail system might have stuck
in some weird characters, this is what I got:
<?php
error_reporting(-1);
ini_set('display_errors',true);
ini_set('display_startup_errors',true);
class TestClass {
public $a=20;
public $b=10;
public function TestClass($a= null, $b=null) {
if (!is_null($a))
{
$this->a = $a;
}
if(!is_null($b))
{
$this->b=$b;
}
}
public function printAB() {
echo $this->a." ".$this->b."\n";
}
}
$inst1 = new TestClass(3,50);
$inst2 = new TestClass();
$inst1->printAB();
$inst2->printAB();
?>
Outputs:
3 50 20 10
as you expect. What is the question?
