PHP :: How Do You Assign A Various Number Of Variables?

Trying To Assign Number To Image..
I am working on a countdown script that will display the number of days to go to an event. I am after a graphical version. I have the code working that displays the amount of days to go to the event but I now want to display that number as a graphic.

Whats the way of parsing the varible with "19" in it to make up a graphic? I have graphics for digits 0 - 9 made. Do you use some sort of array?

side, correct?

Right now i have ot build a for loop to assign the values

The Same Operation On A Number Of Variables.
I have a big number of variables, mostly data from the form.
I want to convert all empty variables into "NULL".
Obviously for each variable I could write:
if (empty($a)) $a=="NULL";
if (empty($b)) $b=="NULL";...and so on....
But let's say I have like a hundred of them.
Is there any way to write it in just a few rows ???

Multiply A Number Of Variables...
I been wondering which way is the correct way to code this .... i have 5 variables i need to add together then multiply by 5.

So i got this:

$Total = $StrengthInput + $DexterityInput + $DefenceInput + $AgilityInput * 5;

Then i wondered would it be better to do this:

$Total = $StrengthInput + $DexterityInput + $DefenceInput + $AgilityInput;
$NewTotal = $Total * 5;

Get Unknown Number Of Variables From POST Or GET.
I am trying to create a page that redirects users to an advertiser's page. The reason for the redirect is statistics about who clicks where.

The situation is simple when I only need to redirect them to a page, but some of the ads on my site include forms which put data in either POST or GET and I need to know how to allow my redirect page to take that data from POST or GET, whatever that data is, and pass it on to the page that the data were intended for.

I think that once I get the data I can simply create a hidden form, on the redirect page, with the data from POST or GET already in it. However, I don't know how to get an arbitrary number of variables from POST or GET.

Cannot Re-assign $this ...
I'm one more guy having the cannot re-assign $this problem.

someone left a php4 file here containing the lines

|function linkbar()
|{
|if(func_num_args() == 1)
|{

|$this = func_get_arg(0);
|return;
}
...
|}

inside a php4 class definition. func_get_arg(0) in this case delivers
an object - working fine in php4. I struggled a bit with the &
referencing (while not really understanding it and the problem) but
gave up. how must I modify the code to get it to work in php5?

PHP 5 Re-assign $this PROBLEM
Just a quickie, in case it's been covered, like a million times or
something. I'm self taught, and thought I was being pretty clever when building a "messaging" class.

The idea was to abstract "html email", "text email" and "sms message" up a
layer into a "message". To get a message started, I call on something like this:

$msg = new Message("sms");
Message (which re-assigns the $this variable) then looks something like
this:

class Message{
var $message_hash;
var $message_path;//this can be changed, in case stuff is moved in future...
function ryan_Message($type=""){//starts the whole thing
switch($type){
case "html"://this means an html email
include_once("HtmlMessage.php");
$this = new HtmlMessage();
break;
case "text"://this means a text mail
include_once("TextMessage.php");
$this = new TextMessage();
break;
case "sms"://this means an sms message
include_once("SmsMessage.php");
$this = new SmsMessage();
break;
}// end switch
}// end function
}// end class

Each class has methods that are named the same, but act a little
differently, so, basically, I can use the same set of commands to compose a
message and send it, regardless of what type of message it is.

Things work fantastically under php4, but I know that when I swap over to
php5, it's going to throw a hissy fit, because reassigning $this is not
allowed.

Aside from going around the Message class, and just starting messages of a
particular type from scratch:

Is there some sort of cunning retro-fit I could do to the Message class, so
I don't have to trawl through thousands of lines of code?

Assign Value To Variable
Is there any way I can use a function to create a variable and assign
a value to it? I have a Perl script that returns some LDAP
information:

sn=Shore
givenname=Mike
logintime=20041008153445Z
logindisabled=FALSE

Instead of parsing this text and assigning the values, I was wondering
if a function exists where I can pass a variable name and a value, and
the variable would be created.

ie. somefunc("sn", "Shore")

Would create the variable $sn and assign the value "Shore" to it.

Fatal Error: Cannot Re-assign $this
i am running a code created with php4 on a php5 engine and I am running into problems with the $this . In php4 its a variable and in php5 its a ref to a class object (if am right)

I get the following error in a class "Fatal error: Cannot re-assign $this in {path}" which is caused by this line "$this = new $db( $serv, $user, $pass, $dbName );"

How can i resolve this ? am thinking of renaming $this to something like $this_var but then this is likely not to work.

Assign Table Value As A Session??

Assign Function Output To Variable??
I've found some references to this topic at :
http://forums.devshed.com/showthrea...ion+to+variable
but it does not seem to be working for me.

here's a snippet...

<? PHP
function listPeople ($getArray)
{
foreach ( $getArray as $val )
{
echo "$val, ";
}
}

$foo = listPeople($splitDirector);

The function works, and as you can see i'm simply trying to assign the output of the function to $foo. But instead, the output is written to the page where I assign it... like a print or echo statement, and the variable $foo is empty.

How To Assign Data In A Table Field To A Variable

Assign MySQL Function Result To PHP Variable
I know to use: mysql_fetch_row($result) to convert a row from a SQL query result set into an array for use with PHP. but in the case of SQL queries that return one value, such as calls to MySQL functions, is there another PHP mysql api function I should use.

For example, right now I use a "workaround" technique from PHPBuilder:
$result=mysql_query("SELECT COUNT(*) FROM tablename");
list($numrows)=mysql_fetch_row($result);

Rather than using this "workaround" code is there a way to simply assign the result of the MySQL function query to a variable.

$result=mysql_query("SELECT COUNT(*) FROM tablename");
$numrows=mysteryfunction($result);

Order Number Or Tracking Number
I need to create some kind of random number within a persons session that can be inserted into a customer id column for their orders, customer, and credit card tables.

Unless their is a better way to link a customers information together between a few tables besides using auto increment. Things could get screwed up for me if I use auto increment, especially if someone submits their information but does not actually place an order.

My question is " How can I create a random order number that can be used within a persons session and will stay the same throughout the whole program for that one person? "

Same Named Variables.. Or Addressing Variables In A Loop
I'm just starting to program in PHP.. fairly new to programming in general... and I've run across a (probably simple) programming problem I hope someone can help me with. I'm sending variable names through an HTTP get that are generated through a foreach loop. The names are along the lines of name1=, begin1=, end1=, name2=, begin2=, end2=.. etc. The number is the number of the current cycle through the loop. My problem is addressing the variables on the next page... namely how do I evaluate those variables in a loop? I want the value of name1.. but obviously

for (i=1; i<3; i++)
{
echo "$name$i";
};

is not working. Is there an easy way to do this?

Passing Variables & Dummy Variables
Hi! thanks for all the previous help - I've made some progress & have dropdowns and a checkbox; however I have 2 probs which I can't figure out: grateful for any further help. THANKS!

1. Not sure how to code so that user can query from just 1 or all of the dropdowns (at the moment unless they select the correct answers from each dropdown - no results!) = defeats the whole purpose of searching. By selecting from menu options user selects from 2 diff tables.

[the page allows user to search catalogue by selecting year of release, artist, music type - results from 2 tables need to be selected & sent to mysql.

I just don't know how to code it so that user must make an initial selection to get any results, and whichever menu options they choose "add them together" if you like to make a complete query.... sorry my coding just isnt deep enough!

A friend suggested using a dummy variable but as I'm a bit out of my depth; I need to get some help!

The coding I've done so far;

Passing My Variables With Forms Variables
how to carry variables onto the next page along with the forms variables. I need to carry my own over too, but when I press submit on the form page only the forms variables carry over, not my own ?? I have two drop down menues on my form that provide two values "start & end" which I require to go with my own variables.I have tried "a href=" link which carries my variables but not the forms variables.

<?php
echo"<form method=get action=somepage.php?one=$one&two=$two&three=$three&four=$four>";?>
also tried
<a href=somepage.php?one=$one&two=$two&three=$three&four=$four&start=$start&end=$end

Persistant Variables - Application Variables
In the books I have read about PHP I haven't been able to find any descriptions of how to set variables that persist in the servers memory, in the way that Application variables persist in Cold Fusion.

In CF, if I set an application variable then any of the application pages that are run will have access to those variables. And you can put complex arrays of data in the Application Variables and then access these variables at any time, without having to reload those variables for each page when it loads. I expect you can do this is PHP, but I can't find any info about how to do this.

Variables That Change Session Variables
I'm currently writing a mulit-page form app that uses a session to
retain data from each form element in order for the user to jump
between pages, then the final data is passed to a calculation script.

However, I've noticed that if I assign a session variable to another
variable, which then performs a mathematical calculation, the session
variable changes.

i.e. $_SESSION["inflation"] = 4;

$temp_inf = $_SESSION["inflation"];
if ($_SESSION["inflation"] =="RPI") {
$inflation = $rpi;}
else {$inflation = ($temp_inf/100.0);}

now it equals = 0.04

How can I take a value from a session and perform operations on it
without altering the original session value.

Form Variables To Session Variables
I am writing a small script that consists of two pages: page one displays a bunch of values from a DB (ie. First Name, Last Name, Phone Number). On this page you will find a form that follows this format:

<input type="text" name="edit_firstname" size="20" maxlength="35" value='Bob'>
<input type="text" name="edit_lastname" size="20" maxlength="35" value='Smith'>
<input type="text" name="edit_phone" size="20" maxlength="35" value='5552222'>

So when you see the page there will already be a 'default' value in each line (which is information extracted from a DB). This works perfectly and has been tested thoroughly.

On the second page I have the following code:

$editfirstname = $_POST['edit_firstname'];
$editlastname = $_POST['edit_lastname'];
$editphone = $_POST['edit_phone'];

What I am trying to do is this: the default value for edit_firstname from the form is 'Bob' by default, but the user can change this in the input field on the first page. This value, whether changed or unchanged, should then be stored as edit_firstname and by calling up the function $_POST[''] on the second page I want to transfer the value to the variable $editfirstname.

However, it seems that $_POST['edit_firstname'] and the other fields do not return a value at all, hence $editfirstname = '' or $editfirstname = 'NULL'. I have never tried to do things this way before.

Number Of Records

What should I be using?

Help With Getting A Number Of Posts
Hi, I've been trying to make a message board of sorts, and I'm having trouble getting the number of posts in each forum to show correctly. The two tables in mysql im trying to use in order to do this are a table called info, and a table called forumlist. Forumlist has two columns, one with forum_id, and one with forumname. Right now it has three entries, Test Thread, Game Thread, and Discussion Thread, with forum_ids of 1, 2, and 3 respecitively. In the table info, there is a bunch of columns pertaining to the author, the description, but those don't really matter, the one column that does in info is the column forum_id which is an integer I am using to keep track of which thread is in which forum.

Right now there is only one entry in the info table, and that has a forum_id of 1. I have been trying to get it to show that there is one total post in the Test Thread, and 0 in the two others, but for some reason it keeps saying there is one in the Game Thread, and 0 in the others. I tried changing the forum_id to 2 in the info table, but then it said that I had one post in the Discussion Thread and 0 in the others. It seems to be jumping ahead by one for some reason. I could use some help, here is my code:
