Import CSV file into array - php

Question

Thank you for the response. I will give it a try and update my question, I have my own code but it is a bit messy to show all. My problem is that I do not get the indexes right.
I use:
$products = array();
$lines = file('data_stock.csv', FILE_IGNORE_NEW_LINES);
foreach ($lines as $key => $value)
{
$products[$key] = str_getcsv($value);
}
And I manage to read the data, but this will give me an error:
if ((int)$products[$_sku] > 0 && isset($products[$_sku])) {
Error: Notice: Undefined index: test-product-1 in....
The 'test-product-1' is from the sku column in the csv file
Output from
echo '<pre>';
print_r($products);
echo '</pre>';
gives:
Array
(
[0] => Array
(
[0] => sku
[1] => qty
)
[1] => Array
(
[0] => test-product-1
[1] => 3
)
[2] => Array
(
[0] => test-product-2
[1] => 6
)
[3] => Array
(
[0] => test-product-3
[1] => 30
)
)
I am trying to use a csv file to be imported into the array to replace
$products = [
'test-product-1' => 3,
'test-product-2' => 6,
'test-product-3' => 30
];
But I can not produce the same array when I import from the CSV file, which will cause problems. Examples for CSV to array: http://php.net/manual/en/function.str-getcsv.php
CSV file:
sku,qty
test-product-1,3
test-product-2,6
test-product-3,30
Next step is to extend the script to handle prices. I need to be able to pick up these variables from the CSV file too. And use them inside the for loop.
sku,qty,price,special_price
test-product-1,3,100,50
test-product-2,6,99,
test-product-3,30,500,300

I think the problem is that when you store the row, your storing it indexed by the row number ($key will be the line number in the file). Instead I think you want to index it by the first column of the CSV file. So extract the data first (using str_getcsv() as you do already) and index by the first column ([0])...
$products = array();
$lines = file('data_stock.csv', FILE_IGNORE_NEW_LINES);
foreach ($lines as $value)
{
$data = str_getcsv($value);
$products[$data[0]] = $data;
}
If you want to add the first row as a header and use it to key the data...
$products = array();
$lines = file('data_stock.csv', FILE_IGNORE_NEW_LINES);
$headers = str_getcsv(array_shift($lines));
$products = array();
foreach ( $lines as $value ) {
$data = str_getcsv($value);
$products[$data[0]] = array_combine($headers, $data);
}
The removes the first row of the array using array_shift() and then uses this row in the array_combine() as the keys for each row. With your test data, you would get something like...
Array
(
[test-product-1] => Array
(
[sku] => test-product-1
[qty] => 3
[price] => 100
[special_price] => 50
)

I used following code in my project and its working fine for me.
I used csv_reader PHP library for it.
You have to put this library in your library folder and import it into file where you want to read your csv.
include_once('../csv_reader.php');
$read = new CSV_Reader;
$read->strFilePath = "file_name_with_path";
$read->strOutPutMode = 0; // 1 will show as HTML 0 will return an array
$read->setDefaultConfiguration();
$read->readTheCsv();
$dataArr = array();
$dataArr = $read->arrOutPut;
In $dataArr, i will get the result,
