First item in POST array

[run_GMoney]

will $POST[0] return the first item in the array and likewise would $POST[$n] return the nth item? Do I need to know the name of the form value it's retrieving the info from?

AFAIK, you cannot access the $_POST array with numerical indexes, as those arrays use associative indexes only. Depending on your PHP config settings, you may be able to use $argc and $argv instead.

You can use the array_keys function to generate a list of the names of all posted variables and then cycle through it.

I don't get anything displayed when I set the value of $row like this:

$row = mysql_fetch_array($result);

And I try to display $row[1].

So in this instance, does $row also not get indexed with numbers like $row[0], $row[1], $row[2], etc...?

Essentially what I want to do is store some numbers that I retrieve from a database in an array and then loop with a for statement.

mysql_fetch_array() works with numerical indices. Are you sure your query returned a result ?

I get a value for the first item ($row[0]) but nothing after that. I have tested to make sure it successfully executing the loop, and it is. My incrementing variable is also increasing by one each time, which it should. But for some reason, it's not grabbing the next value.

Do your loop like this, so you don't have to worry about counter values...

do {
print values here
} while ($row = mysql_fetch_array($result));

I can get values to print out with a while loop, that's not an issue. But I need to incorporate my print statements with a for loop that's already created. So that's why I need numerical indices. I'm using a for loop to show all the items in the $POST array.

$form_fields = array_keys($_POST);

for ($i = 0; $i < sizeof($form_fields); $i++)
{
...

You want to see the values of the $_POST array?

Try this:

    while($x = each($_POST)) {
            echo "$x[0] => $x[1]<BR>";
    }

No I've got that part working. I can get the values from the POST array with the for loop code that I just posted. What I needed was to be able to incorporate a second array into that loop. A was hoping to be able to associate numerical indices with the

$row = mysql_fetch_array($result);

That way I could put it all together like this:

$form_fields = array_keys($_POST);
$row = mysql_fetch_array($result);
for ($i = 0; $i < sizeof($form_fields); $i++)
{
  $curField = $form_fields[$i];
  $curValue = $_POST[$curField];
  echo $curValue;
  echo $row[$i];
}

Unfortunately with this code, only the first value in the $row() array is printed, even though every item in the form_field() array gets printed.
