<body>
<?php
$price = 3.95;
$tax_rate = 0.08;
$tax_amount = $price * $tax_rate;
$tatal_cost = $price + $tax_amount;
$username = 'james';
$domain = '@example.com';
$email_address = $username .$domain;
print 'the tax is ' .$tax_amount;
print "\n\n";
print 'the total cost is ' .$total_cost;
print "\n\n";
print $email_address;
?>
</body>
</html>
以上,執行結果是 the tax is 0.316 the total cost is 4.266000 james@example.com
很怪,因為我有加入"\n" 去空行啊 ？ 怎麼會有這麼奇怪的結果
請各位幫幫忙啊 ^^ ~~
