Convert from String to Integer

Anon

I got 2 variables, $word and $letter, which I get with an HTML form. Here's a part of the code:

<form action="calc.php" method="post">
<font size=2>Word</font><br>
<input type=text name="word" size=20 maxlength=19>
<font size=2>Letter</font>
<input type=text name="letter" size=3 maxlength=1><br>

Now, I want to convert these 2 variables into 2 Integer variables, so I can then multiply these 2. Anyone know how?

may be you can use this code:

<?
settype ($word, "integer");
settype ($letter, "integer");
?>

then, you can treat them as integer for calculation.

PHP does not have strict types, you can just do

$iOutput = $word * $letter;

But ofcourse, this only works if you type numbers into the $word and $letter variable.

Just do it.

$result = $word * 2;

PHP is easy

Thanks guys, but it doesn't work ^¸
It work when I use numbers, but when I try with letters, the result is always 0.

You mean the fields are

"one" and "four" for example?

Then it's going to be hard, because you have to be able to handle every number that fits in an integer! so, it'd be better if you can limit your fields...for example, if you limit them to be only 1 digit numbers, then you just have 10 if statements and that'll work.
