What are some best practices for troubleshooting PHP download link issues related to Apache configuration?

Issue: If you are experiencing issues with downloading files through PHP links, it may be due to Apache configuration settings not allowing the download of certain file types. To solve this issue, you can add specific directives to your Apache configuration file to allow the download of desired file types. ```apache <FilesMatch "\.(?i:pdf|docx|pptx)$"> ForceType application/octet-stream Header set Content-Disposition attachment </FilesMatch> ``` This code snippet will force the download of PDF, DOCX, and PPTX files by setting the Content-Type to application/octet-stream and adding a Content-Disposition header with the value "attachment". Make sure to adjust the file extensions in the regex pattern to match the file types you want to allow for download.
