server-side maximum character limit for textarea?

[ewwatson]

Hello everyone, I found a few methods but this stuff is still somewhat greek to me, so which do you guys prefer? Thanks!

$clipped_string=substr($_POST['textarea'],0,512);

or

<?
$position=14; // Define how many character you want to display.
$message="You are now joining over 2000 current";
$post = substr($message, 0, $position);
echo $post;
echo "...";
?>

or

$charLimit = 500;
if (strlen($_POST['desc']) <= $charLimit)
{
// do something
} else {
// do error
}

or

<?php
if (strlen($_POST['input']) > 300) {
// appropriate rejecting mechanism
} else {
// do what you want with it.
}
?>

Hello, I want to set a maximum amount of characters in my textarea on the server side. I already have this set on the client side. So I am just looking for the best method to add to my pre-existing formmail.php. Thanks!

It depends on whether or not you want to clip the text at the last character in the middle of a word or not. If you don't care, then using substr [php.net] will be fine. If you want to make sure you don't clip a word you could use wordwrap [php.net].
