[RESOLVED] foreach loop using array

[twitch]

Hello gurus,

I've been pounding my head against the wall on this one. It must be something simple I'm missing. I have a text field that posts ($_POST['case_ids']) a comma separated value such as 10067,10076 When I use explode to break it up it should make it an array. However when I use it in a foreach loop I get an invalid argument error. If I do a check for is_array() it fails the check.

If I print the array I get:

Array ( [0] => 10067 [1] => 10076 ) 

So I thought maybe I get the error because the individual array elements don't have commas between them so I wrote this to put commas in between each element except the last:

$cases = array();
	$numItems = count($case_ids);//get count of array
$i = 0;//initialize counter
foreach($case_ids as $key => $value){
	if($i+1 != $numItems) {
	$cases[$key] = $value.',';
}else{
	$cases[$key] = $value;
}//end if $i+1
$i++;
}

However this new array still gets the invalid argument error. Are these not valid arrays?

Any help would be greatly appreciated.

Thanks in advance,
Twitch

The output in your first example is valid.

<?php

$s="10067,10076";

$a=explode(",",$s);

foreach ($a as $key=>$value) {
   echo "\t $key \t $value \n";
}

?>

I mean, this works.

You shouldn't need to mangle the thing by adding commas. What part of your code is producing the error?

Well after more testing I'm convinced my code is correct as well. I was using this code to generate a PDF using mPDF and I'm thinking the issue is lying with the mPDF class because when I get rid of all mPDF code I don't get the invalid argument error.

Thanks for the reply, dalecosp. Much appreciated.
