php - fopen() in PHP not creating or writing to txt file

问题描述

I get the following Warning:

Warning: fopen(Uploaded_Files/dataFile1.txt): failed to open stream: Permission denied in /opt/lampp/htdocs/PHP_Course_Practice/Superglobals/data_upload.php on line 17

I am using XAMPP for 7.4.8-0
Using my MacBook as a Localhost to learn PHP. I am quite new to coding.
I've tried:
- writing the whole Path to the file dataFile1.txt in fopen() but it's not solving the problem
- Checked in PHP.ini that allow_url_fopen is on
- included whole path at the top of PHP file but also not solving the problem
- Also tried chown -R www-data:www-data folder (where folder was full path to the folder) and Terminal said chown: www-data: illegal group name
- Also tried sudo dseditgroup -o edit -a daemon -t user wheel (first to Superglobals Folder and then later to root folder of Xampp)
The full Path that fopen() is trying to reach and write to file is: /opt/lampp/htdocs/PHP_Course_Practice/Superglobals/Uploaded_Files/dataFile1.txt
I'm not keen on using 777 as I read in various articles that it's not safe to use.

The Code is:

<?php
$document_root = $_SERVER["DOCUMENT_ROOT"];
$fileRoot = $document_root . "/PHP_Course_Practice/Superglobals/Uploaded_Files/dataFile1.txt";
echo "Root: $document_root";
include($document_root . "/PHP_Course_Practice/Superglobals/Uploaded_Files/dataFile1.txt");
?>
<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title></title>
  </head>
  <body>

<?php
if (isset($_POST["submit"])) {
  $dataFile1 = fopen("Uploaded_Files/dataFile1.txt", "w");
  $dataFile1Txt = "My age is " . $_POST["age"] . ".";
  fwrite($dataFile1, $dataFile1Txt);
  echo $dataFile1;
  fclose($dataFile1);
}
?>

<form action="data_upload.php" method="post">
  <input type="text" name="age">
  <input type="submit" name="submit">
</form>

  </body>
</html>
