Question

I have a form on a website that once completed holds the values in an array. I wish to put the contents of the array into a txt file, each submission on a new line, values seperated by ‘-‘:

info-info-info-info
info-info-info-info

I’ve tried using:

foreach ($clean as $info) {
    $file = fopen("userinfo.txt", "w");
    fwrite($file, $info);
    fclose($file);
}

This only put the last part of the array in the text file and overwrites the file on each submission.

Using:

$results = var_export($clean, true); 
file_put_contents('userinfo.txt', $results);

writes all the info to the file correctly but stores as a var dump, and overwrites on each submission. I don’t know how to format it to achieve what I need. Any help greatly appreciated.

Answer 1

You are basically writing a CSV (comma-separated values) file. PHP has the right function to do the job builtin: fputcsv (As an added bonus it will also properly handle escaping of values containing the separator themselves);

if($h = fopen('./path/to/file', 'a')) {
  fputcsv($h, $clean, '-');
  fclose($h);
}

Use fgetcsv to retrieve the data at a later point.
