how to combine code

Bar2aYunie

Hello,

I've got a some parts of code that I cannot seem to combine together in such a way that it works...

here's the first part:

$arrays = array(
  array($price1, $price6, $price11),
  array($price2, $price7, $price12),
  array($price3, $price8, $price13),
  array($price4, $price9, $price14),
  array($price5, $price10, $price15)
); 

base_m=5; 
   {$item['arrays'] = round ((($item['arrays']+5) *1.85),0);  

         $item['arraysfinal'] = $base_m*(ceil(($item['arrays'])/$base_m));}
//the arrays are now renamed to arraysfinal

Well that was basically the idea, but it doesn't work... I got 5 arrays with each three prices in every array. but I cannot seem to get them to work.

Right now, it works if I put that same part of code (the last bit) seperately for all 15 prices. That gives 15 rows of code and I'm looking for a way to combine that with the help of an array.

Anybody any idea? Thank you very much!

There's no way that this code is complete. What have you left out?

I didn't leave anything out, it was just two pieces of code, though I had no idea how to combine those... I got somebody to help me out so that's fixed.

Though maybe you can help me with the second question?

I got a part of my code endlessly double... I have certain amounts I want to show on the page, underneath each other. And in the worst case, there can ben 24 different amounts. Anyway, in case there isn't an amount in the db, it has to ignore that fact. So the value must always be bigger than 0.

The way I did that is:

<?php 
if ($item['amount1'] > "0") { echo $item['amount1'] ?> <br /> <?php }
if ($item['amount2'] > "0") { echo $item['amount2'] ?> <br /> <?php }
// and so on

As you can see, I am checking for a value bigger than 0 for every single amount, then display it. Do you have any idea how I can put this in an array or something, but then display this with one line of code?

First of all, don't jump in and out of PHP just to print out "<br />".

<?php
if ($item['amount1'] > "0") echo $item['amount1'] . "<br />";
if ($item['amount2'] > "0") echo $item['amount2'] . "<br />";
?>

Secondly, I still don't see where this information is coming from, thus to me, it is incomplete. If you are pulling from a database, for example, you might use:

$result = mysql_query($some_query);
while($row = mysql_fetch_assoc($result))
  {
  if ($row['amount1'] > "0") echo $row['amount1'] . "<br />";
  if ($row['amount2'] > "0") echo $row['amount2'] . "<br />";
  }

Whereas, if you are pulling the data from a tab-delimited file:

$file = fopen($some_file_location, "r");
while(!feof($file))
  {
  // read a line
  $line = fgets($file);
  // split columns into array
  $value = explode("\t", $line);
  // Output columns
  if($value[0] > 0) echo $value[0] . "<br />";
  if($value[1] > 0) echo $value[1] . "<br />";
  }
fclose($file);

Yes, I know that it is incomplete, I just stated the part that I needed help with. Yes, it is pulling the information from a database, so those lines come first. And thx for the suggestion bout the
<br>´s.

Though these lines go on from amount 1 to amount 24 tops. So to avoid using the same lines 24 times, do you know how I can get a repeat action or something?
