how would i use the while loop to add the extra array to a foreach loop?

at 1st i thought id have to to the array_combine.. ...that way i can make an extra key and value using the 2 arrays i need. But i still can't figure how to get the extra item into the foreach....once i combined my arrays i tried this

$details = array_combine($ _POST['photoT'], $_POST['captionT']);

// Loop through the POST items
foreach ( (($_POST['picT'] as $picT => $picStart)) && ($details as $photoName => $picCaption)) )

{

$nameCapsA = $xmlobj->addChild($picS tart);
$nameCapsA->addAttribute(" name", $photoName);
$nameCapsA->addAttribute(" caption", $picCaption);

}

You can only use 1 array as a foreach() loop's argument.

Am I right in thinking the amount of files you upload will be the same as the amount of captions you have?

The reason I suggested you do it all in one loop, is because (if you are having the same number of items -- above) you could use the array key given from the foreach loop to access the same index of a different array.

Consider this:

Expand|Select|Wrap|Line Numbers
  1. $array_1 = array ( 1, 2, 3, 4, 5, 6 );
  2. $array_2 = array ( "one", "two", "three", "four", "five", "six" );
  3.  
  4. foreach ( $array_1 as $key => $value )
  5. {
  6.     echo "{$value} = {$array_2[$key]}<br />";
  7. }
  8. // Produces:
  9. // 1 = one
  10. // 2 = two
  11. // ... etc.

yes you are right in suggesting that but as i have three arrays it's not that easy......ahhhh h but?

what if i have a while loop to generate one and and the use a foreach loop within the while loop for the $key & $value...would that work better? I will do a test and post my code here

Do you mean you have a multi-dimensional array, or 3 seperate arrays?

Can I please see your upload form; I can't make sense of what's happening here.

the form fields are generated with php, below is what is generated. I'm trying to make an array that can be used within the foreach....i dont really know how many arrays I need but i have 3 picT, photoT, captionT.....i' ve named the fields picT[] photoT[] and captionT[] as to use them as an array when i generate the xml file



code....
Expand|Select|Wrap|Line Numbers
  1.             echo '<td><center><p><a href="'.$img_path .'"><img src= "'.$path.$item[$n] .'" height="100" width="100"></a></p></center>';
  2.             echo '<center><p><input type="hidden" name="picT[]" value="pic'.$pn++.'"/></p></center>';
  3.             echo '<center><p><input type="hidden" name="photoT[]" value="PHOTO '.$pto++.'"/></p></center>';
  4.             echo '<center><p><input type="text" name="captionT[]" value=""/></p></center>';
  5.             echo "<center><p><a href=imgEdit.php?img=$img_path> > Edit Image < </a></p></center><br></td>";

Folks, Ever since reading an interesting article in Linux Format on PHP whereby suggested code writing was made that could enhance performance on a server, I've started testing various bits of code everytime I found more than one method to perform a single task.

What about an enhancement of foreach loops which allows a syntax like that: foeach(int i in 1..10) { } // forward foeach(int i in 99..2) { } // backwards foeach(char c in 'a'..'z') { } // chars foeach(Color c in Red..Blue) { } // using enums It should work with all integral datatypes. Maybe we can step a bit further: foeach(int i in 1..10, 30..100) { } // from 1 to 10 and 30 to hundred

I came across a reference on a web site (http://www.personalmicrocosms.com/html/dotnettips.html#richtextbox_lines ) that said to speed up access to a rich text box's lines that you needed to use a "foreach" loop instead of a "for" loop. This made absolutely no sense to me, but the author had posted his code and timing results. The "foreach" (a VB and other languages construct) was 0.01 seconds to access 1000 lines in rich text box,...

Summary: Use foreach(..) instead of while(list(..)=each(..)). --==-- Foreach is a language construct, meant for looping through arrays. There are two syntaxes; the second is a minor but useful extension of the first: foreach (array_expression as $value) statement

Is it safe to remove elements from an array that foreach is working on? (normally this is not the case but not sure in php) If so is there an efficient way to handle it? (I could add the indexes to a temp array and delete afterwards if necessary but since I'm actually working in a nested situation this could get a little messy. I guess I could set there values to null and remove them afterwards? Thanks, Jon
