Hi there!
I'm making an upload script, where I want to replace ":" with "-" - ex: "USER_ID:1345" with "USER_ID-1345". Also I was wondering how I can find the file extension - ex: ".rar".

I want to replace
try
def. mixed str_replace ( mixed search, mixed replace, mixed subject [, int &count])
how I can find the file extention
explode() the file name string against . (period) and the last element of the arry is your extension. or
try
def. string substr ( string string, int start [, int length]) to check last 4 cahrs == '.rar'
there is a file out there called php.chm Try to find this. this is the php ref manual. this file is extremely helpful.

Like this?
Code: Select all
str_replace($userid, "USER_ID:", "USER_ID-")
and
Code: Select all
$file_extension = substr($filename , strrpos($filename , '. ') +1);
if($file_extension != "rar") {
echo "The file isn't a rar file!";
}
