_Construct question

[John Comerford <johnc@xxxxxxxxxxxxxxxxxxxx>]

Hi Folks,

I am still pretty new to PHP and I have a question regarding classes and 
using _construct.  Up until now I have been creating my classes as follows:

class test1 {
var $name;
function test1($pName) {
  $this->name = $pName;
}
}

So I when I create a new class I can assign 'name' by doing '$t1 = new 
test1("test1");'

As part of another thread I noticed the _construct function which (if I 
am correct) does more or less the same thing:

class test2 {
var $name;
function _construct($pName) {
  $this->name = $pName;
}
}

I have fished around a bit and cannot find why one might be better than 
the other.  The only thing I can think is that maybe you need to use 
_construct to be able to use "extends" ?

Is this the case ?   What is the advantage/disadvantage of using 
_construct as opposed to using a function with the classname ?

Thanks,
 JC
