Question

im trying to add table data from mysql to csv and output them to browser using php.

PHP:

$rows = $t->db->query("SELECT * from Animals");
$output = fopen('php://output', 'w');
fputcsv($output, array('Column 1', 'Column 2', 'Column 3'));
while ($row = $rows->result_array()) fputcsv($output, $row);

but im getting error:

Message: Array to string conversion

on the line where the while loop is, i don’t seem to see where the problem is.

thanks

Answer 1

result_array() returns all the results, which is an array of arrays.

Change

while ($row = $rows->result_array()) fputcsv($output, $row);

To

foreach ($rows->result_array() as $row) {
  fputcsv($output, $row);
}
