What are the common challenges faced when trying to set up a PHP development environment like Xampp?

One common challenge when setting up a PHP development environment like Xampp is configuring the correct file permissions for the web server to access files in the htdocs directory. This can lead to issues with file uploads, writing to files, and executing scripts. To solve this, you can adjust the file permissions of the htdocs directory to allow the web server user (e.g., www-data) to read, write, and execute files. ```bash sudo chown -R www-data:www-data /opt/lampp/htdocs sudo chmod -R 755 /opt/lampp/htdocs ```
