If you have a piece of php code sitting in a file, you can use it anytime by
including or requiring it. Say you have a file named add.php and in it you
have:
--- Top of file ---
<?php
function add($addend1, $addend2) {
return ($addend1 + $addend2);
}
?>
--- End of file ---
in another file named page calc.php you can do a:
--- Top of file ---
<?php
require 'add.php';
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$sum = add($_POST['addend1'],$_POST['addend2']);
echo "<br>The sum of {$_POST['addend1']} and {$_POST['addend2']} is
$sum<br>\n";
}
?>
<form method="post" action="calc.php">
<input type="text" name="addend1" size="10"><br>
<input type="text" name="addend2" size="10"><br>
<input type="submit" name="submit" value="Add them">
</form>
--- End of file ---
