在PHP中使用字符串末尾的问号

Question

I'm new to php, but wasn't able to find a straight answer online, so decided to ask Stack Overflow.

I have a variable, and I want to make a statement similar to the following:

if ($var has a question mark at end)
{
$var = ($var - question mark)
}

Thanks in advance!

--EDIT--

I ended up using the following:

if (substr($var, -1) == "?")
{
$var = rtrim($input, "?");
}

Thanks again for the quick feedback. God I love this site.

Simple answer:

$var = rtrim($var, '?');
