[SOLVED] String limit

[thefollower]

How do you stop a string input being too long by cutting off the remaining chars from the string once it exceeds a set number of chars ?

 

So like say max length was 50 characters.. and some one typed 52.. it will cut off the 2 characters at the end ?

<?php
$string = "too long string";
$length = 8;
$new_string = substr($string, 0, $length);
?>

Depends, if your DB is set to a length, yes, it will truncate.  So you want to verify length via PHP before writing it to the DB.

You could use substr with an if statement.  Something like this would probably do the trick:

 

if(strlen($_POST['input']) > 50){

$newstr = substr($_POST['input'], 0, -49

}
