PHP- count function?

Question

Anyone know a PHP function that allows you to count characters in a text box?

I'd like to let users, who register on my website, know if the password or username they are trying to register is longer than, oh, say 8 characters.

I can't seem to find any function for this. I guess it would have to count the amount of characters within a variable.

Answer 1

If you want to stick with PHP rather than embedding the previously suggested Javascript, you should use the STRLEN function as documented here http://www.php.net/strlen

Answer 2

You don't need to count.
You use strlen()
But you will have to use the trim() function to make sure that you have removed any leading or trailing spaces first.

Answer 3

If you just want to show the user how many characters they are typing, i would use something like this...

script type="text/javascript">
function countChar(str)
{
textcount = str.length + " characters typed";
document.getElementById('textCount') = textcount;
}
