How to rename extension of file in directory with PHP?

Question

I have a file in a directory name.processing and I want rename this file in name.processed

I have this code:

$fn1 = str_replace(".processed", ".processing", $fn);
rename($fn1,$fn);

$fn contain the complete path.

Why the file did not got rename in directory?

I think this is not a duplicate because i know how replace a part of string but i don't know how replace an extension of file in directory

PHP is not always predictable in parameter sequence, you should consult the documentation.

// processing -> processed
// str_replace($search, $replace, $haystack)
$fn_new = str_replace(".processing", ".processed", $fn);
// rename($oldname, $newname)
$rename = rename($fn,$fn_new);
echo "old: $fn, fn_new: $fn_new, rename: ", $rename ? 'success' : 'failure';

http://php.net/manual/en/function.str-replace.php http://php.net/manual/en/function.rename.php

Edit: If it still doesn't work: https://stackoverflow.com/search?q=php+rename

I don't know why but not work :-( – mydb Jul 05 '16 at 17:31
does it return success or failure? – PaulH Jul 05 '16 at 17:39
obtain this: old: , fn_new: C:/wamp/www/prove/WORKSPACE/8bf50820/1467739866.processed, rename: failure – mydb Jul 05 '16 at 17:41
so the string rename is ok, but in directory the file is not renamed – mydb Jul 05 '16 at 17:52
Yeay, sorry typo:`old: $fn`. Now go for http://stackoverflow.com/search?q=php+rename – PaulH Jul 05 '16 at 17:53
sorry i don't understand – mydb Jul 05 '16 at 17:56
@mydb you obtained `old: , fn_new: ...`. The text between `old: ` and `, fn_new` was empty, that was because I had a mistake in my answer. That mistake is corrected. – PaulH Jul 05 '16 at 17:59

Looks like you have the paramters for str_replace backwards.http://php.net/manual/en/function.str-replace.php

Try $fn1 = str_replace(".processing", ".processed", $fn);

(You missed the rename being back to front) – Damien Jul 05 '16 at 17:25
