This code works like a champ:

$michelle="select actor_id, actor_display_name, posted_time, geo_coords_lat, geo_coords_lon, location_name from twitter_csv_test where geo_coords_lat BETWEEN '$lat_1' AND '$lat_2' and geo_coords_lon BETWEEN '$lon_2' and '$lon_1'";
$michelle_query=mysqli_query($cxn, $michelle);
if(!$michelle_query)
{
$rats=mysqli_errno($cxn).': '.mysqli_error($cxn);
die($rats);
}
$michelle_columns=mysqli_field_count($cxn);

//gets the field names from your table and sets them up as the first row in your csv file

$heading=mysqli_fetch_fields($michelle_query);

foreach ($heading as $val)
{
	$output .='"'.$val->name .'",';
}
$output .="\n";


while($michelle_row=mysqli_fetch_array($michelle_query))
{
	for($i=0; $i<$michelle_columns; $i++)
	{
		$output .='"'.$michelle_row["$i"].'",';
	}
$output .="\n";
}

$filename="twitter.csv";
header('Content-type:application/csv');
header('Content-Disposition: attachment; filename='.$filename);
echo $output;

Open in new window


The challenge, however, is that my user wants the headers named "lat" and "long" as opposed to "geo_coords_lat" and "geo_coords_lon." How can I dictate the way the headers appear without changing their name in the database?

Why not change the name in the database?  You might try it like this.  Sure wish we had that test data set!  You might have to quote "long" - can't remember.  I always called it "lon" instead.

$michelle
=
"
SELECT
  actor_id
, actor_display_name
, posted_time
, geo_coords_lat AS lat
, geo_coords_lon AS long
, location_name 
FROM twitter_csv_test 
WHERE lat  BETWEEN '$lat_1' AND '$lat_2' 
AND   long BETWEEN '$lon_2' and '$lon_1'
"
;


$michelle_query=mysqli_query($cxn, $michelle);
if(!$michelle_query)
{
$rats=mysqli_errno($cxn).': '.mysqli_error($cxn);
die($rats);
}
$michelle_columns=mysqli_field_count($cxn);

//gets the field names from your table and sets them up as the first row in your csv file

$heading=mysqli_fetch_fields($michelle_query);

foreach ($heading as $val)
{
	$output .='"'.$val->name .'",';
}
$output .="\n";


while($michelle_row=mysqli_fetch_array($michelle_query))
{
	for($i=0; $i<$michelle_columns; $i++)
	{
		$output .='"'.$michelle_row["$i"].'",';
	}
$output .="\n";
}

$filename="twitter.csv";
header('Content-type:application/csv');
header('Content-Disposition: attachment; filename='.$filename);
echo $output;
