[RESOLVED] Ending stings with a period

[OwenTheSamoan]

I have a string which is a paragraph. I would like to end this sting with a period. I know there are many functions in which I can remove the last character in a string, but what I can't figure out is how can I determine if the last character in a string is a comma, period or exclamation mark? If the last character is not one of these I would like to add a period at the end of the string. In my research in the manuals, I can only find how to cut off the last character in the string. Any thoughts?

Thanks in advance.

Basically, find the string length. With the string length, you can subtract one to get the index of the last character. Then just compare and append a period if necessary:

$len = strlen($str);
if ($len > 0 && $str[$len - 1] != '.')
{
    $str .= '.';
}

That works perfectly. Thank you very much for your help.
