//Exercise in try catch  




<?php

$iDivider = $_GET['divider'];
 
// If divider is 0, don't continue.
 
if ($iDivider == 0) {
    echo "Sorry, number cannot be 0.";
} else {
    echo "Total: " . (5/$iDivider);
}

?>



The exact functionality above can be replicated using the try…catch exception:


<?php
	
$iDivider = $_GET['divider'];
 
// If divider is 0, don't continue.
 
try {
 
    if ($iDivider == 0) {
        throw new Exception("Sorry, number cannot be 0.");
    }
    echo "Total: " . (5/$iDivider);
 
} catch (Exception $e) {
 
    echo $e->getMessage();
 
}

?>
