as a wallpaper website administrator i use php for many of our projects. sometimes its necessary to find out if an image file already exist and to prompt the user to upload a different file because we already have the file in our database. finding out whether a file already exists is easy if you are using php. i dont know much about other languages like asp or cgi, but with php you can use the files_exists() function for checking to see if a file already exits in a website.

so if you want to know how you can check if a file exists with php, you can use the
file_exists() function,

EXAMPLE PHP CODE:

<?php
$filename = '/pathto/file.php';

if (file_exists($filename)) {
echo "The file $filename exists";
} else {
echo "The file $filename does not exist";
}
?>

if you want to give it a try, create a file called checkfile.php and copy and paste the code above and upload to your site. just make sure to change the value of $filename to the file you want to verify and confirm if you already have it in your directories.

hope that helps.

please note, my english is not that good. i speak spanish and im trying to help anyone who can benefit from my knowledge. if you have any comments, please reply to my page here, i would appreciate your comments.

This does not work for me. I'm testing to see if my main masthead graphic is found, and it comes back negative. The file IS there, but the program says it's not.

Please help!

It's good, yes, but what if you just want to check for ANY file, regardless filename or filetype. Like if a directory exists, but is empty?

thanks! i couldn't even tell you weren't a native english speaker until you said so.

stone deft, check out this link: tizag /phpt/fileread.php

once you read the data from a file, you can easily compare it to information you pull from a database. hope that helps!
