ok let say that you have 2 or more variables with same name but there are
difference in numbering And Values like this :
$var1 = 1 ;
$var2 = 12 ;
// etc ..
now you must now how much of number of this varibles before you deal with it
or you must store it on array to know how to count it in the fly like this :
$var[var1] = 1;
$var[var2] = 12;
// etc ..
$var_count = count($var); // give you the count
now you can deal with vars like this :
$i = 1;
do {
$NewVar[NewVar.$i] = $var[var.$i] * $WhatEver ;
$i++;
}
while ($i = $var_count );
And finally you can extract vars by extract() to make them in normal shape
if you get my point

Subject: RE: [PHP] Newbie Question: Variables on the fly
Thanks for the reply Denis,
Let me elaborate a bit.
I have a php page which I want to pass a series of variables via a url
string.
eg
myPage.php?dataPoint1=10dataPoint2=20dataPoint3=30
The thing is I won;t know until runtime how many dataPoints there will be
so I have also included 1 additional url variable
eg
myPage.php?totalDataPoints=3dataPoint1=10dataPoint2=20dataPoint3=30
From there I want to take those data points and do several things with
each of them. The keep things simple lets say I want to multiply each by
3
and then divide it by 2 and put it into a new variable (under the same
naming system).
eg
$xtemp=$HTTP_GET_VARS[totalDataPoints];
do {
A line here which will take each dataPoint and multiply by 3 and
divide by 2 and assign it to a new variable with the same numbering system
(eg $myNewVar1=$HTTP_GET_VARS[dataPoint1]*3/2;
$xtemp--;
} while ($xtemp0);
Make any more sense?
Thanks.

Maybe others will catch on to your intention, but I think you need to
provide a bit more information. For example, what variables do you want
to
create (drawn from a file source, or create on the fly)? Where will they
come from (a database, perhaps)? You could create a script that creates
variables from scratch, following a (hopefully) finite mathematical
formula. Or you could manipulate data that already exists, turning this
data into some kind of variables.
Ultimately, you'll have to give a better of sense of the end result you'd
like.

Subject: [PHP] Newbie Question: Variables on the fly
Hello,
I'm sure this is a newbie question but I don't know the syntax.
I want to create a series of variables within a php script at runtime
with
a for loop.
eg
myVar1
myVar2
myVar3
etc
What is the proper syntax to do this?
Thanks,
Tim
