Not being able to fetch csv with class method - php

Question

I'm having a headache trying to figure this out.
My folder structure is as follows:
index.php
helpers:
API.php
helpers.php
assets:
products.csv
debug:
debug_info.txt
My index file looks as follows:
<?php
require_once 'helpers/API.php';
file_put_contents('debug/debug_info.txt', "New request started");
if (in_array($_GET['action'],array('insertOrder','updateOrder'))){
$date = date(DATE_RFC2822);
$api = new API();
file_put_contents('debug/debug_info.txt', "New: {$_GET['action']} at {$date}\n", FILE_APPEND | LOCK_EX);
file_put_contents('debug/debug_info.txt', "This is the product " . $api->getOrder());
}
API.php
<?php
class API {
private $order;
private $product_table;
function __construct(){
$this->order = $this->setOrder();
$this->product_table = $this->setProductTable();
}
public function setOrder(){return $this->readJSON();}
public function setProductTable(){return $this->readProductsCSV(__DIR__ . '/../assets/products.csv');}
public function getOrder(){return $this->order;}
public function getProductsTable(){return $this->product_table;}
private function readJSON(){
$stream = fopen('php://input', 'rb');
$json = stream_get_contents($stream);
fclose($stream);
return print_r(json_decode($json, true), true);
}
private function readProductsCSV($csv = '', $delimiter = ','){
if (!file_exists($csv) || !is_readable($csv)){
return "Someone f*cked up -_-";
}
$header = NULL;
$data = array();
if (($handle = fopen($csv, 'r')) !== false){
while (($row = fgetcsv($csv, 100, $delimiter)) !== false){
if (!$header)
$header = $row;
else if($row[0] != ''){
$row = array_merge(array_slice($row,0,2), array_filter(array_slice($row, 2)));
$sku = $row[0];
$data[$sku]['productCode'] = $row[1];
$data[$sku]['Description'] = $row[2];
}
}
fclose($handle);
}
array_change_key_case($data, CASE_LOWER);
return print_r($data, true);
}
}
When I use file_put_contents('debug/debug_info.txt', $api->getOrder()); I get the data correctly ( I have to comment all the product_table parts for it to work tho ).
But I can't get the CSV file no matter what I do.
I've ran file_exists() && is_readable ( and they passed ) but still nothing.
If I declare the function readProductsCSV in the index.php it works.. but it seems using it as a method bugs everything.
Could someone please help me?

Logic bugs:
if (($handle = fopen($csv, 'r')) !== false){
^---your csv file handle
while (($row = fgetcsv($csv, 100, $delimiter)) !== false){
^---your csv filename, which SHOULD be the handle
Since you're trying to use a string as a filehandle, you get a boolean false back from fgetcsv() for failure, that false terminates the while loop, and $data stays an empty array.
