Need help with php foreach statement

[jmar]

Hi,

I am just finishing up my cell.php script that includes the forecast on the page here"
http://www.hrmweather.com/cell.php

And as can be seen, the ec forecast is returning 7 icons but the page only really accommodates 5.

This is the statement in the middle of the code that needs to be changed and I need a php guru to keep my sanity I think.

if ($fcstorg == 'EC') {
  foreach ($forecasticon as $i => $temp) {
   $forecasticons[$i] = $forecasttitles[$i] . "<br />\n" .
                        $forecasticon[$i] . "\n" .
                        $forecasttext[$i] . "\n";
  }
  $forecasttext = $forecastdetail;
  foreach ($forecastdays as $i => $temp) {
     $t = explode('<br />',$forecastdays[$i]);
     $forecasttitles[$i] = $t[0];
  }

Is there a way to modify the "foreach"  statements to limit it to the first 5 items in the arrays/ or loops?

Many thanks for the assistance,
Jim

Maybe instead of a foreach, use a for loop instead like:

  for ($i=0;$i<min(5,count($forecasticons));$i++) {

which should take the minimum of 5 or the number of forecasticons less than 5.

Best regards,

Thanks Ken,
I tried that but it didn't work out for the page.

Then I read the forecast.php file's complete instructions (a la Ken True!   ) and followed your advice regarding setting up the page with individual variables being printed out like I do in my main website's dashboard. So I made a duplicate forecast.php page and customized it. This approach worked perfectly! Here is the test page for cell/wap on my site. Following the instructions on the top of your php forecast pages I was able to move the forecast into header'd sections and only use 5 icons across the page as desired for the phones. Still some work to do but this worked well.
