how can I remove a ? from a user input

[shadiadiph]

Hi I am wondering is it possible to remove a ? using php

 

I have a user input field which is called question where the user has to enter a question but it is hard to say if the user would type "What is my middle name" or "what is my middle name?" what I am trying to achieve is that if the user adds it I can remove the ? before storing it to the database any ideas?

Remove all "?" from a string:

<?php
$str = str_replace('?','',$str);
?>

 

To remove only the last character if it's a '?'

<?php
if (substr($str,-1) == '?') $str = substr($str,0,-1);
?>

thanks

 

this would probably be the best one right?

 

$question = str_replace('?','',$question);

 

as I dont know maybe the user might put a period after the ?.
