I am developing a site. I upload image files to a directory "images". using SQL query I generate a list of my required images and each image has a REMOVE link in front of it.
I have not given any href value to any REMOVE link yet. I want to use a secure way to delete the file (So that none of my directory info appears anywhere). What Should I do that When I click on the REMOVE link, the File should be removed.

解决方案

You should call the unlink(string filename)[^] function...

Really easy to use... check it and come back if you have some issues...

HTH! :thumbsup:

PS: anyway a simple "delete files PHP" search in google would have given the same result...

Have a parameter action that specifies the action and also a parameter that identifies the image in the database (an ID column for instance). When the page is called with an action that corresponds to a delete take the parameter ID and fetch the path where it is in your directory structure from the database. Now you can delete it and nobody has seen anything for your directory structure.

Hope that helps you get started.
