Verify a file exists

[justinbriggs1]

I seem to be having trouble figuring out a way to search a web server directory to verify that a file exists. For example:1. A user inputs a file name into an input box that he wants to associate with a database record.2. PHP makes sure the file exists before processing the request.Any ideas? Thanks,JW

file_exists does exactly what you need

Oh yeah...thanks maybe you could help me figure out whats wrong with this code:if(!file_exists($folder.$bonus_file))//print "File does not exist";header('Location:http://www.foo.com/bonusadd.php?ERROR=nofile');It seems to work fine when I test it with "print", but won't direct when I try to use the header. Any ideas?THanks,JW

if you want to use header to redirect to another page, you shouldn't output anything above header, so remove print "File does not exist";

That's commented out, I just left it to show that when I swapped the two commands, it functions fine. If I only have the header line, the command is skipped.
