Renaming a file but preserving the extension

[laredotornado@zipmail.com]

Hi,

A question for those of you who always seem to know the one line way
of doing things. I'm using php 4.4.4 and I want to rename the first
part of the file to a particular string. For example, if my input
string were

$input = "/path/to/my/file/12345.jpg";

I would want my result to be "/path/to/my/file/header.jpg", assuming
"header" was my fixed string.

Any slick ways to do this?

Thanks, - Dave

How do you define "extension" ? In the file "nedit-5.5-src.tar.gz" which of
these parts is the "extension" ?

.gz
.tar.gz
.5-src.tar.gz

Good question. You can assume for the purposes of this question that
extension is anything following the "." in which there will be exactly
one "." in the file name.

$x = pathinfo('/path/to/file.txt');
$X = $x['dirname'] . '/' . 'foo' . '.' . $x['extension'];
print $X;

A little more involved, but this will allow for extensions like tar.gz
or tar.bz2, etc. It gets the position in the file name, of the first
".", and keeps everything after.

$p = '/path/to/archive.tar.gz' ;
$file = basename($p);
$p2 = dirname($p) . '/newname' . substr($file,st rpos($file,'.') );
echo $p2;

What about "nedit-5.5-src.tar.gz"? Your code will rename it to
"newname.5-src.tar.gz" whereas ideally it would be named "newname.tar.gz ".

Oh, I see what you meant now. I guess, if needed, one could store some
file extensions in an array to aid with more accurate renaming. Hehe,
I thought I had it. :P
