如何使用 PHP 使用来自外部 CSV 文件链接的数据更新 CSV 文件？

Question

I need help with my PHP code.

We have an e-commerce site made with wordpress and woocommerce. The site needs to import products from another site's CSV-file through a datafeed.

The datafeed setup requires a PHP-file in the website's file system and a Cron Job that executes the PHP-file.

The PHP-file takes the data from 4dkmiglm.csv (cdn.sandberg.world) and appends it to pricelist_206876.csv (in our system)

These two CSV files differ in number of columns.

The PHP-code looks like this:

`<?php
$current = file_get_contents("https://cdn.sandberg.world/feeds/5dkmiglm.csv");

$pricefile = "/pricelist_206876.csv"; 

file_put_contents($pricefile,$current); 
?>`

I placed the PHP-file in the same folder as the pricelist that needs to be updated but nothing happens. pricelist_206876 is not updated as it should be.

The Cron Job is not in the wp-admin panel, but in the control panel (DirectAdmin) of our web host Inleed. The Cron Job command looks like this: /usr/bin/php -q /dev/null "/home/goffero/domains/goffero.com/datafeedcode.php "

I tried modifying the PHP code in various ways with no result. realpath() didn't work.

I changed the write/read/execute system permissions for the files but that didn't solve the problem.

I have a project in magento and the import of the products is done the same way as you want. We take a csv with 10 or more columns but we export only qty and sku in this case.

Here what we have done

    <?php 

    // downloaded file path
    $filesRoot = BP.'/pub/path/to/your/folder/';

    //If folder doesn't exist, create it
    if (!file_exists($filesRoot)) {
        mkdir($filesRoot, 0777, true);
    }

    //their file
    $fileIn = $filesRoot.'5dkmiglm.csv';

    //your file
    $fileOut = $filesRoot.'pricelist_206876.csv';

    $url = 'https://cdn.sandberg.world/feeds/5dkmiglm.csv';

    //Download their csv in your environment
    if(!file_put_contents($fileIn, file_get_contents($url))) {
        die('errore download file');
    } 

    $countLine = 0;
    $fileInOpn = fopen($fileIn, 'r');
    $fileOutOpn = fopen($fileOut, 'w');
    while (($line = fgetcsv($fileInOpn)) !== FALSE) {     

        //position of each column
        if($countLine==0){
            $keyQty = array_search('qty', $line);
            $keySku = array_search('sku', $line);
        }
        $newLineRev = [];
        foreach ($line as $key => $el) {
            if ($key == $keyQty || $key == $keySku) {
                $newLineRev[$keyQty] = $line[$keyQty];
                $newLineRev[$keySku] = $line[$keySku];
                continue;
            }
        }

        // Write in your file
        fputcsv($fileOutOpn, $newLineRev);
        $countLine++;
    }
    fclose($fileInOpn);
    fclose($fileOutOpn);
