A simple calculator written in PHP. Later versions will include more operators.

<!---Head--->
The first box is the first number to calculate, the second is the operator (* / + -) and the third is the second number.

<!---Body--->


 <?php

/* Calculator */


if($submit)
{
if($operator == '*')
{
echo $numa * $numb;
} elseif($operator == '/')
{
echo $numa / $numb;
} elseif($operator == '+')
{
echo $numa + $numb;
} elseif($operator == '-')
{
echo $numa - $numb;
}
} else { ?>
<form method="POST" action="<?php $_SERVER['PHP_SELF']; ?>">
<input type="text" name="numa" size="10">
<input type="text" name="operator" size="2">
<input type="text" name="numb" size="10">
<input type="submit" value="Calculate" name="submit">
</form>
<?php } ?>
