Re: [PHP] Someone please help me with this PHP script.
Aside from the 20 suggestions you've already got, let me add this one:
elseif( ($page != one) or ($page != two) or ($page != NULL) ) {
Echo htmlheadtitleUndefined!/title/headbodypage isn't
defined correctly!/body/html;
}
is useless code. Why?
$page = null; never happens (you made sure of that further up the page).
$page = one; never happens (you already pulled that one out earlier).
$page = two; never happens (you already pulled that one out earlier).
So... if *any* of those returns true you show an error... may I suggest
just changing it to an else instead? a lot more logical(!).
Besides that, were you to move this to its own if() you'd notice it
would always display because if the page is one it *can not* be two
or null, and will thus be displayed. Which means that you'd have an
error which would always display...
oh well, ignore my rant and first make sure to follow the suggestions
provided by others

Hi Johnson,
what is not working in this code?
what is the problem? It will always execute the first part of if condition,
i.e.
It will print
htmlheadtitlePage One/title/headbodyIt works!!bra
href=http://lom.game-host.org/uploads/erik/index.php?page=two;Nice.../a
/body/html
What you are expecting from this script?
One recommendation, it is better to use isset function to check if variable
has been set or not.

Well. Here's an example of the page --
http://lom.game-host.org/uploads/erik/
It is just loading the second page, no matter what. I haven't added the
isset thing yet, but I'll try it. BTW: I'm only 14, so I have yet to use an
older version, and upgrade to a newer PHP. ;-)

The ? And : are a shortcut for ifelse, that could also be written
If (isset($_GET['page'])
{
$page = $_GET['page'];
}
else
{
$page = null;
}
The shortcut is a lot quicker to write (if you understand it) but not as

isset just returns true if a variable has been set, false if not :)

Fwd: [PHP] Someone please help me with this PHP script.
I understand that some people aren't nice to newer people that try their hardest to figure out a problem. Older, more experienced people see this and they think that it's an easy fix, and that they just aren't trying, but in essence.. they are trying just as hard as someone much more experienced. Since they are new, they can have just as much trouble as another person, so they deserve just as much respect in my eyes. Anyway, I have been trying to figure out this problem, and it's just stumped me. It doesn't look as if anything's wrong, and other people've tested it and it works fine. I think I just need someone to make sure my PHP.ini file is normal.. hence the reason I made the phpinfo() file to give much of the information that may help. If anyone needs it (e-mail a yes/no), and I'll send it as an attachment.

Re: [PHP] Someone please help me with this PHP script.
Actually, I disagree with the explenation here. The reasoning behind it
is correct, but the explenation contains a number of incorrect statements.
The = (a single '=') is the so-called assignment operator. This operator
assigns the right-hand value to the left-hand variable. So, when you
write $a = 5; you'll assign the right-hand value (5) to the left-hand
variable ($a).
The == (a double '=') is the comparation operator. This operator
compares the right-hand value to the left-hand value, and returns the
boolean true if it is the same, or false if it is not.
The === (a triple '=') is also a comparation operator, however this one
is more strict. This means (in most cases) that where '==' doesn't care
about if the left-hand value and right-hand value are of different types
(eg. integer vs. string), this one does. So, you could say that when ===
returns true, == would also return true. However, when === returns
false, == doesn't necesserily need to return false aswell.
Now, the assignment operator, as each operator, has a return value. And
the return value of the assignment operator is what probably confused
you. Basically, what happens is that the assignment operator returns
the value it just assigned. So, if you do $a = 5; the return value will
be 5. This is why you can do $a = $b = 5. This will be interpreted as
being $a = ($b = 5); which means: $b = 5 returns 5, which is then
assigned to $a, which makes $a have the value 5.
In most cases, the return value of the thing is ignored. eg. if you do
$a = 5; 5 will be assigned to $a, and the result (5) will be returned.
But since we don't do anything with the return value, it's silently ignored.
So, how do if() and such constructs work with this, you wonder?
if(), and most other language constructs (while(), elseif(), etc) take
an expression as its argument, compare it to true (lazy comparing), and
will continue if it returns true, or stop/skip if it's false.
if() could also be written as if(expression == true), where expression
is anything with a return value (including operators!).
So, if you write if(2 == 2), the return value will be true, which equals
true, and thus the if() will be executed. However, if you have if(3 ==
2) it'll return false (2 is NOT the same as 3), which is obviously not
true, and thus the if() will be skipped.
When we said before, assignment operators return the value they just
assigned, you'll see that: if($a = true) will return true, which is
equal to true, and which will cause the if() to be executed. On the
other side, doing if($a = false) will return false, which is not equal
to true, and which will make PHP skip the if().
Because php uses lazy comparing in the if(), it will not check the
type of the variable/value! This means that for the if, this is true:
if(2 == '2'). And also if($a = 2) (all values are true, except NULL,
false, an empty string, or zero. There is a full table showing these in
the manual). So, doing if($a = 0) will return false, and will skip the
if(). Of course, doing if('2' === 2) will also return false (due to the
use of ===) and will skip the if aswell.
Hope that clears up any misunderstandings that might have been left.
Also, I urgently recommend you to have a look at the wonderful PHP
manual (one of THE best programming/scripting language manuals, if I may
be so bold). A few pages which will surely help you (and also explain
the above):
http://www.php.net/manual/en/language.operators.assignment.php
http://www.php.net/manual/en/language.operators.comparison.php
http://www.php.net/manual/en/types.comparisons.php
http://www.php.net/manual/en/language.control-structures.php
etc.
Please read the manual first, it will answer a lot of your questions.

so if You write
if ($a=5) {...}
it will always be executed (therefore else isn't executed), as
assignment always returns true :]
so when using 'if' You always need to do
if ($a==5) {...}
unless of course Youd want to do an assingment and some code, but then
why not do
$a=5;
...
? :)

[PHP] Someone please help me with this PHP script.
I do not know why this isn't working, but it would be very helpful if
someone looked over it.

$defaultpage = http://lom.game-host.org/uploads/erik/;;
If($page == NULL) {
$page = one;
}
if($page == one) {
Echo htmlheadtitlePage One/title/headbodyIt works!!bra

elseif($page == two) {
Echo htmlheadtitlePage Two/title/headbodyThis is page .
$page . -- a href=\ . $defaultpage . index.php

What is this magical $page variable? Did you conjure it from thin air?
Or are you one of those coders still using a years old deprecated
feature called register_globals who just upgraded their version of PHP
to a version that disables it by default? Since you're the latter (yes I
can read minds from afar), then what you really want is the following
before you start using $page:
$page = isset( $_GET['page'] ) ? $_GET['page'] : null;
Cheers,
Rob.

What is it doing, or not doing?
Try changing the ? to ?php and see if that works.
