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;
?>

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
