Creating csv file with php

Question

I want to create a csv file, but when I run the code, it returns a blank page and no csv file. I use PHP 5. I use the following code:

<?php
    $data = array ('aaa,bbb,ccc,dddd',
                   '123,456,789',
                   '"aaa","bbb"');

    $fp = fopen('data.csv', 'w');
    foreach($data as $line){
             $val = explode(",",$line);
             fputcsv($fp, $val);
    }
    fclose($fp);
?>

Thank you!

Answer 1

Its blank because you are writing to file. you should write to output using php://output instead and also send header information to indicate that it's csv.

Example

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');
$data = array(
        'aaa,bbb,ccc,dddd',
        '123,456,789',
        '"aaa","bbb"'
);

$fp = fopen('php://output', 'wb');
foreach ( $data as $line ) {
    $val = explode(",", $line);
    fputcsv($fp, $val);
}
fclose($fp);
