Smarty remove everything after last character

Question

I have a Smarty variable thats called{$url} and it contains following URL:

$url = https://www.example.com/?parameter=hello:world:itsme

I want everything after the last ":" to be removed.

The result should look like this:

$result = https://www.example.com/?parameter=hello:world

With my knowledge it was only possible for me that I get the following result:

$result = https://www.example.com/?parameter=hello

How can I get this result with Smarty?

Thanks for your help!

Answer 1

Try with explode,array_slice and implode
Like this :-

$url = 'https://www.example.com/?parameter=hello:world:itsme';
$array=explode(':',$url);
$array=array_slice($array, 0, 3);
$url=implode(':',$array);
https://www.example.com/?parameter=hello:world //as o/p

Modified:-
For removing everything after the last ":" use array_pop
Like this

$url = 'https://www.example.com/?parameter=hello:world:itsme:itsme2';
$array=explode(':',$url);
array_pop($array);
$url=implode(':',$array);
https://www.example.com/?parameter=hello:world:itsme //as o/p
