How to generate a CSV file and send it as a POST request without saving it?

Question

PHP

Hello!
Tell me how to generate a CSV file and send it with a POST request without saving it?
How to generate is clear, but how to send the generated data via Guzzle or Http Client to Laravel without saving the file?

Answer 1

You can send a file to guzzle using multipart
https://docs.guzzlephp.org/en/stable/request-optio...
while the contents of the file itself can be a string: parametercontents

$csv_data = 'xxxx;yyy;zzz';

$client->request('POST', '/post', [
    'multipart' => [
        [
            'name'     => 'mycsv',
            'contents' => $csv_data,
            'filename' => 'custom_filename.csv'
        ],
