php Filemtime function showing wrong date

Question

I would like to add the last modified date to the index page , the below code shows the 31/12/1969 is the last modified date.

echo date("d/m/Y",filemtime("index.php"));

Please show var_dump(filemtime("index.php")); - suspect you'll find it says bool(false). Make sure that index.php is the correct relative path to the file you are look for the modified time of. — DaveRandom

I guess the path is wrong. At last on your development system you should increase the error settings.

In case of an erro filemtime() returns false, what what gets casted into 0 by the date()-call.

You should refer your files on the filesystem using (pseudo-)absolute paths.

__DIR__ . '/path/to/index.php';

My guess is filemtime is not finding your file. filemtime will return 0, or something that equates to 0 like FALSE, and then applying date on time 0 will return 0 seconds since the epoch (1st Jan 1970).

Looks like that's what you're getting. I'm also guessing you're using PHP <= 5.1.

@BalluRocks Probably something to do with PHP returning negative numbers for pre-epoch times. I'd suggest DaveRandom's approach and dump out the result of filemtime and see what it says. If it's false, then it's still a path issue.
