PHP export products from database into csv - php

Question

I have to export all my products from database into a csv file when executing the following script but i can't manage to put together the function that returns all my products from database into an array or iterator. My php code is put below. What am i doing wrong? Thank you.
<?php
require_once("config/db-connect.php");
function toate_produsele_active() {
$array_produse = mysqli_query($mysqli, "SELECT product_id, product_name, category_url, product_short_desc, product_price, product_photo FROM mb95_products");
while ($row = mysqli_fetch_assoc($array_produse)) {
print_r($row);
}
}
$f = fopen('php://output', 'wb');
if($f) {
foreach(toate_produsele_active() as $produs) {
$coloane = array(
$produs['product_id'],
$produs['product_name'],
$produs['category_url'],
$produs['product_short_desc'],
$produs['product_price'],
implode('[,]', str_replace('[,]', '[%2C]', $produs['product_photo'])),
);
fputcsv($f, $coloane, ';', '"');
}
fclose($f);
}
?>
My final desired result should look something like this:
1;Titlu produs1;categorie;Descriere produs1;RON;60;5;product_photo.jpg

Answer 1

let's say that toate_produsele_active() it's working as expected. I have created three functions, so the code can be reused and i have added the comments in the code:
<?php
// Create the header for the csv file (ID, Titlu, Descriere, Pret)
function getHeader()
{
$csv = '';
$headerData = array();
$header = 'ID, Titlu, Descriere, Pret';
$columns = explode(',', $header);
foreach ($columns as $column) {
$headerData[] = $column;
}
// the titles are separated by the semicolon
$csv .= implode(';', $headerData) . "\n";
return $csv;
}
// add the products data into an array and then fill the csv file
// with rows. Separated by semicolon
function iterateItems($csv)
{
$data = [];
foreach (toate_produsele_active() as $produs) {
$data[] = $produs['product_id'];
$data[] = $produs['product_name'];
$data[] = $produs['category_url'];
$data[] = $produs['product_short_desc'];
$csv .= implode(';', $data) . "\n";
}
return $csv;
}
function exportAll()
{
// name and location of the file
$csvFile = 'products.csv';
// create the header: ID, Titlu, Descriere, Pret
$csvHeader = getHeader();
// add the header and then the product data into the csv file
$csv = iterateItems($csvHeader);
// save he file (location, file)
file_put_contents($csvFile, $csv);
}
// call the function
exportAll();
