How to break<br> when a specific amount of characters is encountered?

[janhouse00]

Hello,
1)I have a variable that contains about 300+ characters and it will be printed out. And I want to have exactly 50 characters displayed in each single line. So how can I
perform break,<br> on it?

2)I am using the following logic to validate the form that is submitted via POST method, anyway I realize that the user can easily override the entire stuff by using QUERY STRING, say thescript.php?valid=1. Any idea?

<?
if($_POST['username'])
$valid=1;
else
$valid=0;

Sorry if these questions have been raised for tons of times.Thank you.

For the first question, try using substr() and for the second one, if that condition evaluates to true, perform some opperations, if not perform other opperations. Avoid using that $valid.

Last first:
if(!empty($valid)) {
die("Bad, bad guy!!");
} else {
if($_POST['username'])
$valid=1;
else
$valid=0;
}

The first:
Do you want a line break unconditionally? No matter if it's in the middle of a word?
A normal way to do the breaking would be to set the table width to app. accept 50chrs width, then let the spacing do the breaks 😉
