Display array results to the user

Question

I have seen and tried a lot of examples here on display array results to the user but none of them has worked for me.

The closest to what I am looking for, I suppose, is this:

How to display array result

Again, tried it but it doesn't work.

It doesn't work - meaning the page is coming up blank.

When I try varDump(...) and print_r(...), I get results but I can't seem to display the results to the user.

Does anyone know what modifications I need to make to the code below to get to display the results of sourcename, sourceaddress1 and income1?

$rowIDs = $_POST['rowIDs'];
if (is_array($rowIDs) || is_object($rowIDs))
{
foreach ($rowIDs as $id) {
 $sourcename1 = $_POST['sourcename1'. $id];
 $sourceaddress1 = $_POST['sourceaddress1'. $id];
 $income1 = $_POST['income1'. $id];
 echo $id;
 echo $sourcename;
 echo $sourceaddress1;
 echo $income1;
}

[rowIDs] => 1
[sourcename1] => Array
    (
        [0] => Jane Doe
    )

[sourceaddress1] => Array
    (
        [0] => 123 Main Street
    )

[income1] => Array
    (
        [0] => $89,000.00
    )

Answer 1

$_POST['rowids'] is a number, not an array, so foreach ($_POST['rowids'] as $id) is wrong. I'm guessing this contains the number of elements in the other input arrays, so it should be:

for ($id = 0; $id < $rowIDs; $id++)

You also shouldn't have if (is_array($postIDs) || is_object($postIDs)), since the code should run when this input is a number.

The other inputs are arrays, so you need to use array indexing to access them, not string concatenation.

$sourcename1 = $_POST['sourcename1'][$id];

and similar for the other inputs.

Answer 2

sourcename1, sourceaddress1 and income1 are arrays containing one item. For example, $sourcename[0] would return Jane Doe.

For more information regarding arrays please read the documentation.
