PHP Image Upload

[Redapple]

Goodmorning everybody.

Im started using PHP yesterday and i was wondering if anybody has a fully non-bug example of a php upload script. I want to learn how to upload a image true PHP with the follow functions:

- Rename the file once uploaded (Like random name).
- 2,5 MB Max (I believe php is doing bytes so that will be 2500000)

Im sorry if this is the wrong forum, But i just want to learn

Thanks!

if you want to learn why are you asking for a functional fully debugged script? This is not the way it works on a forum. You make an attempt yourself then ask for assistance when you are struggling.
Anyway your request is rather vague. Upload from where to where?

Sorry, I did not know that, I will keep that in mind.

I had a script that just uploaded it to images/ but i doesnt have it anymore. Overwrote it with other sample's.

this function copyes a file or folder, it needs another function (ls_a):
this works perfect.
////////////////////////////////////////////////////////
/// cp function/////////////////////////////////
////////////////////////////////////////////////////////
function cp($wf, $wto){ // it moves $wf to $wto
mkdir($wto,0777);
$arr=ls_a($wf);
foreach ($arr as $fn){
if($fn){
$fl="$wf/$fn";
$flto="$wto/$fn";
if(is_dir($fl)) cp($fl,$flto);
else copy($fl,$flto);
}
}
}
///////////////////////////////////////////////////
/// ls_a function////////////////////////
// This function lists a directory.
// ANd is needed for the cp function.
function ls_a($wh){
if ($handle = opendir($wh)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != ".." ) {
if(!$files) $files="$file";
else $files="$file\n$files";
}
}
closedir($handle);
}
$arr=explode("\n",$files);
return $arr;
}
