It looks like you're building your array just fine. Here though, your
second foreach needs to look like this:
[code]
foreach ($arr as $project)
{
echo $projectbr;
}
[/code]
Your temprorary $arr variable contains only your array of titles, not
an entire row of your 2-dimensional $sonsor_id array. So you do not
need to use the $sponsor key to get at that array.
HTH,

Thanks so much for pointing out that error on $arr, John. You are very
right. Now I realize it's such an obvious error. But I did not notice it
before I posted.

[PHP] help with multidimentional arrays
Hello,
What I intend to do is put the database query results in a
multidimentional array like this.
$sponsor_id['sponsor1'] = ('project1 title', 'project2 title', 'project3
title');
$sponsor_id['sponsor2'] = ('project1 title','project7 title');
Here is the code snippet for doing that:
==
while( ($rec = odbtp_fetch_array($qry)) ) {
if (empty($sponsor_id[$rec[1]])) {
$sponsor_id[$rec[1]] = array();
} else {
array_push($sponsor_id[$rec[1]], $rec[0]);
}
}
==
Now, when the following code is used to print the array $sponsor_id, it
only prints out the keys of the array which are:
sponsor1
sponsor2
Those project titles are not printed out.
==
foreach ($sponsor_id as $sponsor = $arr)
echo $sponsor:;
foreach ($arr[$sponsor] as $project) {
echo $projectbr;
}
==
My expected output should be like:
sponsor1:
project1 title
project2 title
project3 title
sponsor2
project1 title
project7 title
What is wrong? I'd appreciate any help.
Thanks,
Bing
