Question

I’ve found several useful and helpful tutorials and forum posts on this subject. But none I could find display an exact example and implementation of my current scenario.

I am trying to convert my completed query results array into csv format, so I can download the results, properly formatted, in .csv format.

Below is my code:

This is my download action:

<script>
    function getcsv(){
    window.location="script_4.php";
}
</script>
<input type="button" onclick="getcsv()" value="Download CSV">

This is my while() loop merging my query data into a sequential numeric array:

while ($row = mysql_fetch_row($result)) {
$industries = explode(",", $row[3]);
unset($row[3]);
$merge = array_merge($row, $industries);
echo "<pre>";
print_r($merge);
echo "</pre>";
}

My print_r() above echoes out like this:

Array
(
    [0] => 3561
    [1] => The Ace Company
    [2] => [e-mail]
    [3] => Waterproofing
)
Array
(
    [0] => 3562
    [1] => JOJO Associates, Inc.
    [2] => [e-mail]
    [3] => Lab Equipment & Casework
)
Array
(
    [0] => 3564
    [1] => Southern Style Pipe
    [2] => [e-mail]
    [3] => Plumbing
    [4] => Piping
    [5] => Pipe Inspection
)

This is where I am at with the download script, and when I attempt it it loads my html and entire array into the csv with no csv formatting of array data.

header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");

outputCSV($merge);

function outputCSV($data) {
    $outstream = fopen("php://output", "w");
    function __outputCSV(&$vals, $key, $filehandler) {
        fputcsv($filehandler, $vals);
    }
    array_walk($data, "__outputCSV", $outstream);
    fclose($outstream);
}

I solved the problem like so:

header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=exhibitors-$date.csv");
header("Pragma: no-cache");
header("Expires: 0");

// create a file pointer connected to the output stream
$output = fopen('php://output', 'w');
// output the column headings
fputcsv($output, array('ID', 'Company', 'Email', 'Address1', 'Address2', 'City',     'State', 'Province', 'Zip', 'Phone', 'Fax', 'Toll Free', 'Site'));

while ($row = mysql_fetch_row($result)) {
        $industries = explode(",", $row[13]);
        unset($row[13]);
    $merge = array_merge($row, $industries);
    fputcsv($output, $merge);
}
