Use `pathinfo()`. And searchbar. – BlitZ Oct 04 '13 at 10:51

Even typing in "file extension" into the search box on http://php.net would have led you on the right path... – deceze Oct 04 '13 at 10:53

If your input is `sample.jpg.txt` the extension is `.txt`. – deceze Oct 04 '13 at 10:54

This will have been asked multiple times before. Use the search facility or even Google next time. – Martin Bean Oct 04 '13 at 11:02

You can try with explode
$file_name = "sample.jpg";
$pieces = explode(".", $file_name);
echo $pieces[0]; // sample
echo '.'.$pieces[count($pieces)-1]; // .jpg
You can also use this:
$ext = pathinfo($file_name, PATHINFO_EXTENSION);
echo $ext;//jpg

Here one way to find:
<?php
$filename = "sample.txt.jpg";
$ext = substr($filename, strrpos($filename, "."));
echo $ext;
?>

1LOL! :-D Uhm... no. File names do not *require* an extension. Sorry to disappoint. – deceze Oct 04 '13 at 11:03

1Believe him. I've made this error a long time ago, and the result was katastrophal :-) – Luca Rainone Oct 04 '13 at 11:05

Or if the system provide it like that... which means file names do not *require* an extension, and your code needs to consider this! – deceze Oct 04 '13 at 11:09

Cool :) It is core basic without pathinfo we can. Kinda logic useful for developers – Nes Oct 04 '13 at 11:16
