But, when I had my text editor show invisible characters, there were some on that line and line 10. Do you have a text editor that can show invisible characters? On the Mac, the one I really like (and is free) is TextWrangler (http://www.barebones.com/products/textwrangler/ ) and has this capability. This may be part of your problem. Once I got rid of the invisible characters, the example worked without any problems. Also, are you certain there are no spaces or anything (even invisible characters) before ?php? Whenever I've gotten a similar error in the past, that was nearly always the problem. You are welcome to compress the text file and send it to me directly so I can see exactly what it contains. Since you're a PHP rookie, to sum it up: there can not be any output before you start a session. When PHP interprets a file (include or otherwise) it considers anything before ?php as HTML, so it outputs it as HTML (newlines, spaces, whatever). So if you have whitespace before the ?php, then the PHP interpreter outputs it, thus the output before the session_start() error. -Shawn It's an easy mistake to make, not just reserved for rookies ;) I had a similar problem streaming video to the browser, and found that for some reason all the video files were larger than the original and wouldn't play. Turned out (after some very strong words aimed in the general direction of my laptop) that I'd included a header file which was outputting some HTML!

[PHP] Public in Classes
Hi, Just started with object oriented programming and glad I have come across it, just need a few things clearing up. When I make a variable or method public, does this mean that it can be used outside of classes, for instance in other classes or as well as instantiating classes? So if I made it private, it wouldn't be able to be instantiated or extended in other classes, am I right? I have never added public when I am creating methods so I presume its already set as default if you don't add it? Hope you can understand my question. Cheers.

yes, and the answer nearly always lies in trying it out, run this

Re: [PHP] Re: geolocation
This is a slightly OT but along the same lines. I've found that the main way that ISP's and large content hosts control who can access their site and from where is by using BGP routing (Border Gateway Protocol), and other advanced things that are beyond the control of the majority of webserver admins. It allows them to change the routing that information, which is for example, how your ISPs servers know where to forward your data packet to next. However with some funky router, you can get 'magic' IP addresses, like Akami and most ISP's DNS server have. E.g, You will request to access data on a certain Akami IP address, instead and taking 200ms to hit some server on the other side of the world, and come back, it could go to a server sitting in your nearest capital city in 50ms, which is great for video content, and AJAX calls. The thing is, someone in another country could request the same data from the same IP, and the request will automatically be sent to a completely different server, most likely that of one in their capital city (or at least the closest place that has an Akami server containing the required info). Above is just another example of how you can't purely rely on IP addresses, although it is the easiest thing from a webservers PoV, and usually right 90% of the time (as far as I am aware, although haven't tested, nor have any good ways of testing besides Traceroute).

Re: [PHP] Public in Classes
Hi,
I have this piece of code that I have created:
class userQueries {
public function numberUsers() {
$get_users=mysql_query(SELECT * FROM `users` WHERE `online`
NOW()) or exit(../includes/error.php);
}
}
class usersOnline extends userQueries {
public function usersOnline() {
echo mysql_num_rows($this-numberUsers);
}
}
How do I request specific methods in other classes? The error that comes up
is:
mysql_num_rows(): supplied argument is not a valid MySQL result resource
which is somewhat expected as $this only refers to the variables and there
are no variables called numberUsers.

Definitely no ??? I've always found this confusing. If one uses a br tag, you'll get a single line break and everything validates per W3C -- as long as you're not using a xml doctype. If you use br/ or br / tags, then both will generate a line break, but both will also generate W3C shorttag validation warnings. If you use br/br, then you'll get a single line break, but that will also generate a W3C validation error, which is worse than a warning. However, if you read this: http://www.w3.org/TR/2006/REC-xml-20060816/#dt-empty One would think that using br/br or br/ tags are fine, but they're not -- and br isn't even mentioned. So considering all the different ways one can do this, the one that's the least problematic is br. Of course, one could use: div nbsp; /div and side-step the entire issue.

[PHP] Calling methods from others classes
Hi,
I have this piece of code that I have created:
class userQueries {
public function numberUsers() {
$get_users=mysql_query(SELECT * FROM `users` WHERE `online`
NOW()) or exit(../includes/error.php);
}
}
class usersOnline extends userQueries {
public function usersOnline() {
echo mysql_num_rows($this-numberUsers);
}
}
How do I request specific methods in other classes? The error that comes up
is:
mysql_num_rows(): supplied argument is not a valid MySQL result resource
which is somewhat expected as $this only refers to the variables and there
are no variables called numberUsers.
Cheers!

You forgot to return $get_users; from your numberUsers() function
Also in your code you will never free the result nicely which is bad.
In order to count the users, you should possibly also use SELECT
COUNT(*) FROM... and then use the single value that is returned as this
will be more efficient (does not require all the data to be fetched and
sent).

[PHP] OOP - Calling methods from classes that are inheriting?
Hi, How do I call methods from classes that are inherited? I want to add a mysql_num_rows() function to a second class that is an addon to a MySQL query in the first class. The first class will be used in several different classes for different parts of the site so I don't want to directly add the num_rows to the first class method as the query won't just be used for this function. Hope I have made myself as clear as possible! Cheers!

This is exactly the same; you don't need $_SESSION's in this case because all you're doing is POST'ing the data every time.. And that's what you are missing -- it's not continued POSTing! Follow closely, http://www.webbytedd.com/bb/php-run-php/ While I'm using a Submit Post button to go from this script to the next script I am NOT sending any data via the POST. To prove it, use FF and see what's passed. All data is passed/available to the next script because the next script is an include. For example, this parent script has the variable: $test = This is a test; And the next script (either a.php, or b.php, or c.php -- your choice) simply echo's $test. Please note, the contents of the variable $test was NOT passed via a POST, but rather retained because the parent script included the next script. Do you see the difference? Here's another example presenting the same technique in a different way: http://www.webbytedd.com/bb/tedd/index.php All the variables remain intact AND there is nothing in the REQUEST, SESSION nor COOKIE arrays. I have a hard time trying to get people to understand this simple concept. It's so simple that people often overlook how powerful it is. For example, with a little forethought, I think there isn't a script I've written that I could not have used this technique and dispensed with SESSION's all together. That's pretty powerful, don't you think? Do you understand what I'm doing now? no ill-intention meant. That's Okay -- I realize you meant no ill-intent. Neither do I -- I realize that occasionally simple concepts are hard for you smarter guys to get because you have to dumb down a lot to consider what we're talking about. But I think it's an interesting concept to consider. Cheers, tedd at it's simplest is this correct..? index.php ?php $variables = $_POST; include 'anotherscript.php'; ? anotherscript.php ?php print_r( $variables ); //include has access to $variables from parent print_r( $_POST ); //include has access to post data as well ?

1. don't double post, a bit of patience is in order.
2. this has nothing to do with public/private methods.
3. use braces to call a method ... methods are not variables.
4. you can't pass an include file to exit and expect it to run that file
(it will just echo out the string you gave it)
5. the 'foo() or exit()' error handling strategy is rather crap (imho)
... you could do it gracefully instead of just killing the script.
6. I doubt whether `online` NOW() will give you the result your looking for
class userQueries {
public function numberUsers($where = 1) {
$r = mysql_query(SELECT * FROM `users` WHERE $where) or
$this-killMe();

Hi,
Just started with object oriented programming and glad I have come across
it, just need a few things clearing up.
When I make a variable or method public, does this mean that it can be
used
outside of classes, for instance in other classes or as well as
instantiating classes? So if I made it private, it wouldn't be able to be
instantiated or extended in other classes, am I right?
I have never added public when I am creating methods so I presume its
already set as default if you don't add it?
Hope you can understand my question.
yes, and the answer nearly always lies in trying it out, run this
(and if/when you hit a fatal error, comment the offending line and run it
again):

oh yes, it's that simple.
2 things to remember:
1. If you want to see output, actually make sure the function you call
RETURNS any output in the first place. ($hello = Yay!!; isn't
returning anything)
2. parent::* calls on the parent class in a static context. If your
class extends another, it automatically inherits all functions from that
class, unless it overwrites it itself. So you can simply use

oh yes, it's that simple.
2 things to remember:
1. If you want to see output, actually make sure the function you call
RETURNS any output in the first place. ($hello = Yay!!; isn't
returning anything)
2. parent::* calls on the parent class in a static context. If your
class extends another, it automatically inherits all functions from that
class, unless it overwrites it itself. So you can simply use
$this-func() in your child class.
not true (well you can use $this-func() in this case) ... but
parent::* assumes the context your in (i.e. static or not):
?php
class Test
{
static function func1() { echo __METHOD__,\n; }
function func2() { echo __METHOD__, called from , get_class($this),
\n; }
}
class TestTwo extends Test
{
static function func1() { parent::func1(); }
function func2() { parent::func2(); }
}
$t2 = new TestTwo;
TestTwo::func1();
$t2-func2();

use a return statement, just like standalone functions, assuming
you want to output the Yah!!.

In perl it would be (roughly):
