Export database to CSV with columns PHP - php

Question

Here my php script to export database info to CSV file.
I dont arrive to put any structure to correctly tidy my infos in my CSV file.
For example, put all names in a name column, all emails in an email column... etc
include_once('conf.php');
include_once('BDD.php');
header('charset=UTF-8');
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
$bdd = new BDD($conf['bddhost'], $conf['bddport'], $conf['bddname'], $conf['bdduser'], $conf['bddpass']);
$sql = "SELECT * FROM user";
$qry = $bdd->prepare($sql);
// Execute the statement
$qry->execute();
$data = fopen('/tmp/db_user_export_".time().".csv', 'w');
while ($row = $qry->fetch(PDO::FETCH_ASSOC))
{
// Export every row to a file
fputcsv($data, $row);
echo ''.$row['prenom'].' '
.$row['nom'].' '
.$row['email'].' '
.$row['cp'].' '
.$row['information'].'
';
}
fclose($data);

Answer 1

You don't want to use echo as you are creating the file with fputcsv
while ($row = $qry->fetch(PDO::FETCH_ASSOC))
{
// Export every row to a file
fputcsv($data, $row);
}
// reset the file pointer to the beginning of the file
rewind($data);
// dump the csv file and stop the script
fpassthru($data);
exit;

Answer 2

Syntax errors:
$data = fopen('/tmp/db_user_export_".time().".csv', 'w');
^-- ^-- ^-- ^---
You're mixing string quoting styles, so your filename is literally going to contain the characters ", ., t, etc... in it.
Try
$data = fopen('/tmp/db_user_export_' .time() .'.csv', 'w');
^----------^---
instead. Note the change from " -> '.

Since your result is an array, this may help you out:
Convert php array to csv string
if(!function_exists('str_putcsv'))
{
function str_putcsv($input, $delimiter = ',', $enclosure = '"')
{
// Open a memory "file" for read/write...
$fp = fopen('php://temp', 'r+');
// ... write the $input array to the "file" using fputcsv()...
fputcsv($fp, $input, $delimiter, $enclosure);
// ... rewind the "file" so we can read what we just wrote...
rewind($fp);
// ... read the entire line into a variable...
$data = fread($fp, 1048576);
// ... close the "file"...
fclose($fp);
// ... and return the $data to the caller, with the trailing newline from fgets() removed.
return rtrim($data, "\n");
}
}
$csvString = '';
foreach ($list as $fields) {
$csvString .= str_putcsv($fp, $fields);
}
