Php Image Upload Problem?

[ColdEdge]

Hi, I made a PHP upload script that uploads image and adds extra things to the name.Here is the codeThe problem is that the image is upload however if the image name is say 59.png it will be upload as bf6-gsiu5cztf3ci_706h8m121h but, I don't not know how to add extension so for a .png image a .png ext will be added to this so it will look like this: bf6-gsiu5cztf3ci_706h8m121h.png since I tried doing this method$ext = ".jpg";this adds the .jpg text to the end result but when saved onto a computer Photoshop for example dosen't read it as a valid .jpg file since the original file was .pngWhat can I do to echo the extensions?Using either $HTTP_POST_FILES['ufile']['type'] to get the mine type and making php convert it to required echo statement, or is there a different way?-Thx

Extract the extension from the original file name, which is given in $_FILES['ufile']['name']

the problem is that I don't know how... +this line of code renames the file into something random...

$letters = '0123456789abcdefghijklm0123456789nopqrstuvwxyz0123456789ABCDEFGHIKLM0123456789NOPQRSTUVWXYZ0123456789';   srand((double) microtime() * 1000000);   $file_name = '';   for ($i = 1; $i <= rand(22,22); $i++) {   $q = rand() %33;   $file_name = $file_name . $letters[$q]; }

Do you want it to make it random or not?

Right after the loop, you would just add

$file_name = $file_name . "." . $ext;

$ext is the file extension that's extracted from the original file name.

nvm, got the extension to work ^^

You can get the extension using explode and pop:$ext = array_pop(explode('.', $_FILES['ufile']['name']));
