RE: [PHP] OO Question for PHP4
[snip]
Hi all. As the subject suggests, I am using PHP4 and am having something
going on that I don't think should be.
Presume the following code
class Foo {
function Foo () {
return Bar;
}
}
$foo = new Foo;
echo $foo;
$foo comes out as an object. Does this have to be done in two line like
this?:
class Foo {
function bar () {
return Bar;
}
}
$foo = new Foo;
$bar = $foo-bar;
[/snip]
This is correct.
$foo = new Foo; // calls $foo as the object
echo $foo; // echo's an object
Bar would then be a public member of $foo, hence $foo-bar.

Re: [PHP] OO Question for PHP4
Im sure you should be returning a value in your constructor at all?? Ill

Or is there a better design approach I should be reminded of or learn?
Thanks in advance!

From my experience, returning a value from a constructor currently does nothing, in either PHP4 or PHP5. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Constructors always return a reference to the object. A return statement
is disregarded.
Have a look at http://www.php.net/language.oop.constructor in particular
a post in the comments by steffen staehle.

You shouldn't be returning from a constructor.
}
}
$foo = new Foo;
echo $foo;
It's generally bad prcative to echo anything other than scalar types
(strings and numbers). Try using print_r() or var_dump() instead.
$foo comes out as an object. Does this have to be done in two line like
this?:
class Foo {
function bar () {
return Bar;
}
}
$foo = new Foo;
$bar = $foo-bar;
Yes, this has to be two lines. I'm not sure how you'd want to put this
as one. In addition, you should have parenthesis on your funciton
call:
$bar = $foo-bar();
Or is there a better design approach I should be reminded of or learn?
