Question

Thanks for the contributions so far – I can see now that $rowq is not a single array but lots of them – I’d like to bring all the rows back in the array, any suggestions?

First off, the code which brings back my data into an array:

function fetch_questions($page) {
global $link;
$proc = mysqli_prepare($link, "SELECT * FROM tques WHERE page = ?");
mysqli_stmt_bind_param($proc, "i", $page);
mysqli_stmt_execute($proc);


$rowq = array();
stmt_bind_assoc($proc, $rowq);

// loop through all result rows
while ($proc->fetch()) {
//      print_r($rowq);
}


mysqli_stmt_close($proc);
mysqli_clean_connection($link);
return($rowq);
} 

Now, when I `print_r($rowq);’ I get the following, which is all good:

Array ( [questions] => q1 [qnum] => 1 [qtext] => I find my job meaningful [page] => 1 ) Array ( [questions] => q2 [qnum] => 2 [qtext] => I find my job interesting [page] => 1 ) Array ( [questions] => q3 [qnum] => 3 [qtext] => My work supports ABC's objective [page] => 1 ) Array ( [questions] => q4 [qnum] => 4 [qtext] => I am able to balance my work and home life [page] => 1 ) Array ( [questions] => q5 [qnum] => 5 [qtext] => I am clear about what is expected of me in my job [page] => 1 ) Array ( [questions] => q6 [qnum] => 6 [qtext] => My induction helped me to settle into my job [page] => 1 ) Array ( [questions] => q7 [qnum] => 7 [qtext] => I understand the ABC vision [page] => 1 ) Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 )

Now, in my php page I have the following piece of script:

$questions = fetch_questions($page);

And when I print_r $questions, as below:

print_r($questions);

I only get the following back from the array, 1 row:

Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 )

Any ideas why that might be?

Thanks in advance,

Homer.

Your $rowq variable is only holding the last row that was fetched. When you print_r during your fetch loop, each row is fetched into the $rowq variable, and then immediately printed, but because you overwrite the variable each iteration, when the loop completes only the final row is contained within $rowq.

If you want to hang onto all the rows, you can augment your function:

function fetch_questions($page) {
  // ...

  $rows = array();
  while ($proc->fetch()) {
    $rows[] = $rowq;
  }

  // ...

  return $rows;
}

With this code (only the relevant parts are included), every time a row is fetched, it is placed within an array $rows, which then contains all rows when the loop completes.
