Foreach() Question

[Blaine HIlton]

I've been trying for 2 days now to solve this problem, which should be
pretty simple, but it is turning off to not be as simple.

I am trying to pull data out from a form that was POSTed on a previous
page. The code that I have that works is below:

<?php
for ($i = 2; $i <= $stoped; $i++) {
echo '<tr>'
.'<td>Step '."$i".'</td>'
.'<td>Input X</td>'
.'</tr>' ;
}

What I need to do is replace "Input X" with $step1, $step 2, ect..
until $stoped is reached. Before this code I added lines such

$step2 = $_POST["step2"] ;
$step3 = $_POST["step3"] ;
$step4 = $_POST["step4"] ;

to try to isolate the problem. I would perfer to be able to put
$_POST["step2"] directly in the for loop. All of my tries though
ened up with me just printing the line and not pulling the data from
the form.

I was also looking at foreach() and thought this might be what I am
looking for. Something that will loop through the $_POST array.
However what I have tried so far has not worked.

Any help would be greatly appreciated

Huh? What's bad style about echo?

Why is `print' better? print() always returns true, echo doesn't return
anything. AFAIK that's the only difference.

Re: Foreach() Question

Thanks alot for that advice, it really worked well. I am using your
code now and have come up with another problem that perhaps you can
solve. The code I am using is:

$i = -1 ;
foreach ($_POST as $key => $value) {
If (strlen($value) >0 AND $key != "title" AND $key != "author"
AND $key != "submit" ) {
$E->writerange("sh eet1","A1","$va lue");
}
$i++;
}


What I need to do is loop through all of the POST data and write it to
the sheet in cells that go A1, then A2, then B1, B2, C1, C2, D1, D2,
ect.... All the way to 100 possibilities. How would I even begin to
replace A1 in the line:

$E->writerange("sh eet1","A1","$va lue");

with something that will change like that?

Thanks again

PS. Also can you tell me more why you think print is better then echo
?

And because if this, is actually faster (although you'll probably
never physically see the difference without benchmarking).

I only use print() for debugging.

<?php $R = mysql_query("SE LECT ..."); ?>

becomes:

<?php $R = mysql_query(pri nt "SELECT ..."); ?>

or else the code will break.
