Is "$filename" correctly initialized?

Hi -

1. The reason you're seeing "Jan 1, 1970" is because you're passing in a date value of "0".

2. I'm guessing this is probably because "$filename" wasn't initialized correctly, in which case "filectime()" will return "0" and pass it to "date()".

3. Outside of that, your code appears fine. Here's a sample that runs fine (it prints out "found" and the correct date if test file "/tmp/tmp.txt" exists; it prints out "not found" if it doesn't):

PHP Code:
  if (
"<h2>File " $fname " exists!</h2>";
$d date ("F d Y H:i:s."filectime($fname));
"d: " $d;
"<h2>File " $fname " doesn't exist...</h2>";

'Hope that helps .. PSM

Hate to ruin your day, buy you can't get the file creation time...

Three fields in the inode structure contain the last access, change, and modification times: atime, ctime, and mtime. The atime field is updated each time the pointer to the file's data blocks is followed and the file's data is read. The mtime field is updated each time the file's data changes. The ctime field is updated each time the file's inode changes. The ctime is NOT creation time; there is no way under standard Unix to find a file's creation time.


Sorry about that ...
