Pull customer data into all columns in a csv file - php

Question

This is my current code which pulls all data into a single column. I would like it
to pull data into its own column. Thanks for any help
<?php
include('codelibrary/inc/variables.php');
include("session.php");
$obj= new database_class();
$query = $obj->getAnyTableAllData($obj->getTable("var_customer")," and email != '' order by email ");
$filename = 'customer_email.csv';
$fp = fopen($filename, 'w');
foreach ($query as $k=>$v) {
$_csv_data= $v["email"]. "\n";
fwrite( $fp, $_csv_data );
}
foreach ($query as $k=>$v) {
$_csv_data= $v["first_name"]. "\n";
fwrite( $fp, $_csv_data );
}
foreach ($query as $k=>$v) {
$_csv_data= $v["business"]. "\n";
fwrite( $fp, $_csv_data );
}
foreach ($query as $k=>$v) {
$_csv_data= $v["phone_no"]. "\n";
fwrite( $fp, $_csv_data );
}
foreach ($query as $k=>$v) {
$_csv_data= $v["shipping_address"]. "\n";
fwrite( $fp, $_csv_data );
}
fclose($fp);
if(is_file($filename))
{
$size=filesize("$filename");
header("Content-type: application/csv");
header("Content-Length: $size");
header("Content-Disposition: attachment; filename=$filename");
header("Pragma: no-cache");
header("Expires: 0");
readfile($filename);
exit;
}
else
{
echo "Invalid file!";
}
?>
This is my first post on here and I've found all the info here very informative. Thanks for all you do.
EDIT:
Here is the current code with the syntax error
<?php
include('codelibrary/inc/variables.php');
include("session.php");
$obj= new database_class();
$query = $obj->getAnyTableAllData($obj->getTable("var_customer")," and email != '' order by email ");
$filename = 'customer_email.csv';
$fp = fopen($filename, 'w');
# let's get keys into an order that you like
$fields = array('email','first_name','business','phone_no','shipping_address');
foreach ($query as $k=>$v) {
// put the fields for this row into an array
foreach ($fields as $field) {
$data[] = $v[$field];
}
fputcsv($fp, $data);
unset($data);
}
fclose($fp);
if(is_file($filename))
{
$size=filesize("$filename");
header("Content-type: application/csv");
header("Content-Length: $size");
header("Content-Disposition: attachment; filename=$filename");
header("Pragma: no-cache");
header("Expires: 0");
readfile($filename);
exit;
}
else
{
echo "Invalid file!";
}
?>

Answer 1

For CSVs, instead of fwrite, you can use fputcsv, you just pass it an array of columns to insert in the row.
$array = array('column one contents', 'column two contents');
fputcsv($fp, $array);

Answer 2

I would suggest looking into fputcsv.

Answer 3

It looks like your code was looping through all the data, printing out the email. Then looping again and printing out the first_name... I haven't tested it, but this uses fputcsv to write the file - I changed only those parts of the code.
<?php
include('codelibrary/inc/variables.php');
include("session.php");
$obj= new database_class();
$query = $obj->getAnyTableAllData($obj->getTable("var_customer")," and email != '' order by email ");
$filename = 'customer_email.csv';
$fp = fopen($filename, 'w');
# let's get keys into an order that you like
$fields = array('email','first_name','business','phone_no','shipping_address');
foreach ($query as $k=>$v) {
// put the fields for this row into an array
foreach ($fields as $field) {
$data[] = $v[$field];
}
$lines[] = $data; // add the row of data to $lines
unset($data);
}
fputcsv($fp, $lines);
fclose($fp);
if(is_file($filename))
{
$size=filesize("$filename");
header("Content-type: application/csv");
header("Content-Length: $size");
header("Content-Disposition: attachment; filename=$filename");
header("Pragma: no-cache");
header("Expires: 0");
readfile($filename);
exit;
}
else
{
echo "Invalid file!";
}
?>
