Loading An array

[perrio]

Problem:

Misunderstanding of how an associative array is loaded.

Issue:

I have some code like this: (this is exact)
while($data[] = mysql_fetch_array($result,MYSQL_ASSOC)) {
}

The variable $data is passed to a function that will print a pdf table.

I'd like to manipulate some values on the rows as the '$data' variable is loaded. Then I'd like to pass it to the pdf function.

If I try to manipulate values in the loop above I get: "Notice: index 'such and such' is undefined.

Anyone have a suggestions?
(I do not want to change the pdf function that i pass data to.)

Thank You.

Building an array using $data[] will result in numeric indexes. Same as doing this:
$data[0] = myaql_fetch(... // 1st row
$data[1] = mysql_fetch(... // 2nd row
...
So you have an array of arrays. To manupilate a given value do something like:
$data[1]['whatever'] = 'Something else';

Or do the manupilating as the records are being fetched.

while($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
  // Manupilate $row
  $row['whatever'] = 'Value';

  //Store
  $data[] = $row;
}
