hi all,
I'm a bit confused with this and I hope you can help me:
I have a "Mother" class and a "child" that extends Mother.
The child's constructor should call Mother's constructor.
Now the question is:
How should child's constructor call mother's constructor?
a) Mother::Mother();
b) $this->Mother();
I guess the second way is the right one, but I'm confused because:
1) both methods work;
2) both methods are in the manual;
can you help me to understand this (so I can sleep again ;-) )?
TIA

The code:
<?php
class Mother
{
var $v;
function Mother()
{
echo "I'm the Mother<br>\n";
$this->v=1;
}
}
class ChildA extends Mother
{
function ChildA()
{
Mother::Mother(); // <--- is this correct? why?
echo "I'm the childA<br>\n";
}
}
class ChildB extends Mother
{
function ChildB()
{
$this->Mother(); // <--- is this correct? why?
echo "I'm the childB<br>\n";
}
}
$a=new childA();
$b=new childB();
echo "\$a->v: $a->v<br>\n";
echo "\$b->v: $b->v<br>\n";
?>
