Php Guys, Are you aware of any function or method where I can prevent downloads ? Imagine a page with a lot of links. Like: links to pages and links to imgs or links to downloads. Now, imagine I fetched that page with curl and the user is viewing the links present on the page. Q1a. Now, if I were to prevent any downloads from the download links. How would I do it ? Q1b -. Any php function that manages this prevention ? Q1b - If not, then any workarounds you can think of ? I'm thinking of str_replacing the download links so they no longer showup as download links but as something else such as nothing. Q2a. How would you get your cURL script to spot a download link and get it to not appear on your user's screen ? Q2b. Would you get the script to check for the file extension that would reveal if it's a viewable file (html page, img file, etc.) or a downloading file ? Q2c. What are the long list of download file extensions ? When I cURL fetch or build my own web proxy or build my crawler, have to make sure they ignore download links.
