Lamez Posted March 23, 2008 Share Posted March 23, 2008 1. I am working with images, and is there a function where I can resize a picture? 2.This is one is kinda hard to explain, so let me explain what I need a certain function for: Alright, when a user uploads a image, I want the script to delete their old one, well the image name is hased, except the last part of the name is their username. The image name looks like this: 5c435de5d9db471ca31b5b028eaf2acd-lamez.png here is the code to get the image name. md5($new_filename)."-".$user.".".getExt($bfilename); as you can see, before the extension is their username, so is there a function that can take last part of the filename before the extension, and tell if it is the user that is trying to upload a new image?

To retrieve the username from the filename of a file use: $image = '5c435de5d9db471ca31b5b028eaf2acd-lamez.png'; list($image_name_hash, $username) = explode('-', pathinfo($image, PATHINFO_FILENAME)); echo 'Hash: ' . $image_name_hash . '<br />'; echo 'Username: ' . $username; Link to comment https://forums.phpfreaks.com/topic/97466-functions-questions/#findComment-498736 Share on other sites More sharing options...
