why are there ":" in every input-element?

<html>
<title>
test
</title>
<body>
<div align="center">????
<form id="form1" name="form1" method="post" action="1.php">
??:<input type="text" name="username" id="username" />
??:<input type="text" name="pass" id="pass" />
??:<input type="text" name="email" id="email" />
<input type="submit" name="button" id="button" value="??" />
</form>
</div>
</body>
</html>

and the 1.php:

<?php if(isset($_POST['button'])) {
echo "??????: ".$_POST["username"]."";
echo "?????: ".$_POST["pass"]."";
echo "?????: ".$_POST["email"]."";
echo "????: ".$_POST["button"]."";
}
?>

Yes in the PHP Manual you will find everywhere

This feature has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

in functions for global Variables like $_GET, $_POST, $_SERVER

But I don't know any solutions for this problem, sorry

Please Pay P80.

<?php

//CONDITIONAL STATEMENTS - PROBLEM SOLVING
if ($_POST['amount'] <> null )
{
if ($_POST['amount'] > 80)
{
$change = $_POST['amount'] - 80;
echo "You're change is :". $change." ";
}
else if ($_POST['amount'] < 80)
{
$change = ($_POST['amount'] - 80) * -1;
echo "Not enough. Please pay additional :". $change." ";
}
else
{
echo "Thank you for giving exact amount.";
}
}
?>

Hi aiioef, Its not a big problem , Try this, <?php error_reporting(E_ALL ^ E_NOTICE); ?> include this code on every top of the php file. That's all
