Merge csv files [closed]

Answer 1

To do this in PHP you would do something in the lines of:

1. Open a file handle where the merged csv data can be written to
2. Read all the filenames from the source dir
3. For every file that ends with ".csv", append its content to the merge file

Ex.

$csvdir = './csvdir';
$result = fopen('./merge.csv', 'w');

if ($handle = opendir($csvdir)) {
    while (false !== ($entry = readdir($handle))) {
        if (substr($entry, -4) === ".csv") {
            $csvcontent = file_get_contents($entry);
            fwrite($result, $csvcontent);
        }
    }

    closedir($handle);
}

fclose($result);
