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 ?

$test = substr($test, 0, strpos($test, "."));
echo $test;
?>

You need strrpos instead of strpos. – Americanism

Answer 1

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

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. – Wiggle

@Andrew, interesting solution!) – Octane

@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 – Experientialism

if the string is a url it will strip everything but the filename – Expediency

This didn't quite format correctly for files with characters such as 「 or 」 – Helm
