Run a small phpinfo() script on both servers... take note of the version numbers being used, and take not of the config setting register_globals on both... my guess is that register_glabals is set to OFF on your local machine, being a newer install.

Question: Does PHP4 code have to be written differently for Windows servers? If so, is there a code resource describing the differences? (the only information I can find is on installation on Win servers) No, not really. There are a few functions that won't work on windows because they access things that are in unix (crypt() for one, I think). But, any basic code will run on any server with PHP. Now, if you're using special modules, then they must be installed on each server, obviously. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] novice question
JD,
This is how you would do it:
?
$ab = add($a,$b);
echo$ab;
?
- or you could do it directly like this -
?
echo add($a,$b);
?
- or my personal preference -
?=add($a,$b)?
===
?
function add($a,$b)
{
$ab =$a+$b;
return $ab;
}
?
A quick read of the section on functions in the online manual would be a
great resource. In fact, I recommend checking the manual before posting to
this list. It's a great tool and contains user comments. Chances are that
if you have a problem, someone else has already run into it and posted the
solution in the manual. Here's a link:

Hi thanks for reading this.
This problem is difficult to get across, this is what happens:
A) On a html page I ask users how many inputs they wish to enter, say 3. The
3 is stored as a variable called $NoPols.
B) Then in the code below, a loop creates $NoPols (3) forms to take the
users inputs.
The problem is that the same name($Yourpol) is used in each of the created
forms, and i dont know how to get around this problem.
I would like to know if it is possible to create a page which has a number
of forms, the number of which is decided by the user(on a start page), so
the user can submit as many inputs as they want from one page.
Sorry if I've wasted your time,
I'd be very grateful for any assisstance with this problem,
thanks a million,
Brendan

RE: [PHP] Novice Question
name each field with an array name. I know the following works with
checkboxes; try it with text fields:
input type=text name=poly[] value=
input type=text name=poly[] value=
input type=text name=poly[] value=
input type=text name=poly[] value=
then, in your php script called from the form, you'll access the polynomials
using poly[0], poly[1], poly[2], poly[3], etc.
You know how many fields were created, because you created them; so you
could pass the number of created fields in a HIDDEN value ($NoPols) from the
form. As you examine each field, you'll determine if it's empty or not.
for( $idx=0; $idx$NoPols; $idx++ )

if( strcmp( , $poly[$idx] )

Re: [PHP] Novice Question
yeah, it definitely works with text fields too. You can also do something
like:
input type=text name=poly[?=$i;?]
where $i will then be the key of the resulting array $poly. it doesn't seem
necessary in this case, since the numbers will probably be consecutive, but
if you wanted an associative array for some reason this can be useful.

I would like to know if it is possible to create a page which has a number
of forms, the number of which is decided by the user(on a start page), so
the user can submit as many inputs as they want from one page.
Sorry if I've wasted your time,
I'd be very grateful for any assisstance with this problem,
thanks a million,
Brendan

with this type of naming convention, how would you write a javascript
function to access these form elements for client side
validation? JavaScript vomits when accessing
window.document.frmName.poly[].value???

input type=text name=poly[] value=
input type=text name=poly[] value=
input type=text name=poly[] value=
input type=text name=poly[] value=
then, in your php script called from the form, you'll access the
polynomials
using poly[0], poly[1], poly[2], poly[3], etc.
You know how many fields were created, because you created them; so you
could pass the number of created fields in a HIDDEN value ($NoPols) from
the
form. As you examine each field, you'll determine if it's empty or not.
for( $idx=0; $idx$NoPols; $idx++ )
{
if( strcmp( , $poly[$idx] )
{
... do something with field ...
}

I wish to create multiple input fields on a single form, I think(sorry
..could you advise?)
I'd like a page that has multiple input fields, but I dont know how to
access the individual inputs.
Say the user wanted to enter three inputs(polynommials in this case)
so they get a page with three input boxes,
Enter polynommial here:
Enter polynommial here:
Enter polynommial here:
How would I dynammicaly create the input boxes and name the inputs. Thanks
for your time on this, I sorry I didnt explain this clearer in the first
place,
Thanks,

Hi thanks for reading this.
This problem is difficult to get across, this is what happens:
A) On a html page I ask users how many inputs they wish to enter, say 3.
The
3 is stored as a variable called $NoPols.
B) Then in the code below, a loop creates $NoPols (3) forms to take the
users inputs.
The problem is that the same name($Yourpol) is used in each of the
created
forms, and i dont know how to get around this problem.
I would like to know if it is possible to create a page which has a
number
of forms, the number of which is decided by the user(on a start page), so
the user can submit as many inputs as they want from one page.

Hi,thanks for reading this!
This problem has got me beat! I cant figure out how to insert a minus sign
into each element in an array of strings.
I keep getting the error that the first element in array_push has to be an
array, no matter what method I've tried, and I cant think of any more!
Im trying to isolate terms in polynommials, which Ive stored in an array m[]
like this:
$m[0]=-3x_1^6/7-4x_2^3/5;
$m[1]=-4x_3^2/3-7x_4/7;
/*Each element in m has two terms, and I want to isolate these by exploding
on the minus sign, thus giving me four elements, which then need to have a
minus inserted into them.
I take one of the four elements in $ss, and for each character I push it
into a temporary storage array $test, then I reverse $test so the term is in
the correct order, and then I insert the minus sign at the start. But
funnily enough, there seems to be a flaw in my logic or code. What Ive
written so far is*/
$ss=explode(-,$m);
for($cnt=1;$cntcount($ss);$cnt++)
{
for($waa=0;$waa$cnt;$c++)
{
array_push($test,$ss[$waa])
}
array_reverse($test);
array_push($test,-);
array_push($real,$test);
I would be extremely grateful for anyones assistance, thanks a million,
Regards
Bren

Hi,
THANK YOU for reading this.I would really appreciate it if someone
could
please email me if they know any easy way or an existing function for
removing an unknown ammount of space characters from an array.
Iam having an awful lot of trouble trying to remove multiple space
characters from an array,
ie. x + y
123456789
where there are three or more spaces in a row(rep'd above by 234 678),
basically weird user input.
I have written code already, but I cant see where Ive gone wrong, here it
is
if you care to look at it, and have a good chuckle, told you I was a
novice!
I included the start page that allows you to see what the code does, in
you
want to look at it.
Thank you for your time, I'd really appreciate any replies!

Not sure what this means.
Also I cant get the sizeof function to work no matter what syntax i use, i

If the above doesn't work, then maybe there's something wrong with
your install.
