We often see an error message "Username must be between 5 to 10 characters" displayed on a site while registering for an account.Do you know how to put this feature on your website.Yes,you can and its just a 1 minute game.We use a string function "strlen" to find the length of a string.So we apply this here in our script.

if( strlen($username) <6 || strlen($username) >12)
{
print "Username must be between 6 to 12 characters!";
}

Perhaps you can apply some more security on this script.You can also apply this script on the password textbox.

PHP stands for PHP: Hypertext Processor which is a server-side scripting language and it processes HTML Forms outputs.The basic syntax for PHP is:-

echo "Hello World!";
?>

Now i'm giving you a simple PHP poll script which you can use anywhere in your website as it is an open source script.
So for this you will need two pages: index.php and poll.php

Index.php- Now put the following code in your index.php file.









poll.php- Now put the following code in your poll.php file.


$vote = $_REQUEST['vote'];
$filename = "poll_result.txt";
$content = file($filename);
$array = explode("||", $content[0]);
$yes = $array[0];
$no = $array[1];
if($vote == 0)
{
$yes = $yes + 1;
}
if($vote == 1)
{
$no = $no + 1;
}
$insertvote = $yes."||".$no;
$fp = fopen($filename,"w");
fputs($fp,$insertvote);
fclose($fp);
?>
