How to remove all data after last dot using php ?

I test my code. It's echo just aaa

I want to show aaa.bbb.ccc

How can i do that ?

<?PHP
$test = "aaa.bbb.ccc.gif";
$test = substr($test, 0, strpos($test, "."));
echo $test;
?>

You need `strrpos` instead of `strpos`. – jeroen Feb 08 '16 at 09:21 — jeroen, Feb 08 '16 at 09:21

You can utilize the function of pathinfo() to get everything before the dot

$str = "aaa.bbb.ccc.gif";
echo pathinfo($str, PATHINFO_FILENAME); // aaa.bbb.ccc

`pathinfo` would be best for files. – Sougata Bose Feb 08 '16 at 09:27
@Andrew, interesting solution!) – maximkou Feb 08 '16 at 09:27

@Sougata true, the reason I propose this solution is that I saw the string end with .gif and to me every string accepted function is just a way to manipulate a string :D – Andrew Feb 08 '16 at 09:44
if the string is a url it will strip everything but the filename – Francesco Oct 27 '17 at 00:56
This didn't quite format correctly for files with characters such as `「` or `」` – Typewar Nov 24 '19 at 23:04

You can try this also -

$test = "aaa.bbb.ccc.gif";

$temp = explode('.', $test);

unset($temp[count($temp) - 1]);

echo implode('.', $temp);

O/P

aaa.bbb.ccc

strpos — Find the position of the first occurrence of a substring in a string

You need to use strrpos

strrpos — Find the position of the last occurrence of a substring in a string

$test = "aaa.bbb.ccc.gif";
$test = substr($test, 0, strrpos($test, "."));
echo $test;

O/P

aaa.bbb.ccc
