Output:
public protected private
im a bit confused. ive been googling around and came across this explination
i am referring to shankars post
in his post in the protected explination he instantiated the grandpa class and tries to access the name property but says it would return a fatal error. but with the child class daddy it has no problem of accessing the name property. why is that??

@NogDogAug 28.2019 — #PS: Quick example I threw together:<i>
</i><?php
class Foo
{
public $one = 1;
protected $two = 2;
private $three = 3;
}
class Bar extends Foo
{
public function test($name)
{
if(isset($this->$name))
{
echo "This worked: '$name' is {$this->$name}n";
}
else
{
echo "Nothing found for '$name'n";
}
}
}
$test = new Bar();
foreach(array('one', 'two', 'three') as $name) {
echo "$name:n";
$test->test($name);
if(isset($test->$name))
{
echo '$test->$name = '.$test->$name."n";
}
else
{
echo '$test->$name is not known.'."n";
}
}
Output:
<i>
</i>one:
This worked: 'one' is 1
$test->$name = 1
two:
This worked: 'two' is 2
$test->$name is not known.
three:
Nothing found for 'three'
$test->$name is not known.
