如何在PHP中回显正斜杠
[英]How do I echo forward slash in php
问题描述
I want to echo forward slash in php as follows 
我想在PHP中回显正斜杠，如下所示
<a class="submenu" href="<?php echo base_url('products').'/'.rawurlencode('Agarbatte/Candle');?>"
Agarbatte/Candle is not a directory but when i do this, href takes this as directory and give me the error page not found. Agarbatte/Candle不是目录，但是当我执行此操作时， href将此目录作为目录并给我未找到的错误页面。
Any help will be appreciated. 任何帮助将不胜感激。

A slash in the URL will always be treated as a directory separator. URL中的斜杠将始终被视为目录分隔符。 And if you replace it with something else you won't have a slash anymore. 而且，如果将其替换为其他东西，您将不再有任何斜线。 But that's most likely the easiest solution.. 但这很可能是最简单的解决方案。
If you have a 1:1 mapping between the path in the URL and your filesystem you are out of luck. 如果URL路径和文件系统之间有1：1映射，那么您将很不走运。 If your application uses a "routing layer" though, you can modify it to not treat the / as a separator when some criterium is met. 但是，如果您的应用程序使用“路由层”，则可以修改它，使其在满足某些标准时不将/视为分隔符。

Just use 'urlencode' on the 'Agarbatte/Candle'. 只需在“ Agarbatte /蜡烛”上使用“ urlencode”。 I do not see a special need for 'rawurlencode'. 我对“ rawurlencode”没有特别的需求。

Though you can use the urlencode() function as others have said, I recommend not getting into this habit. 尽管您可以像其他人所说的那样使用urlencode()函数，但我还是建议您不要养成这种习惯。 Assuming you have these products in a database, use the id and you'll never run into these issues. 假设您将这些产品存储在数据库中，请使用id并且永远不会遇到这些问题。
For example if the Candle product has id of 6 in the database... the PHP should resolve to: <a class="submenu" href='products/6'> 例如，如果Candle产品在数据库中的id为6，则PHP应该解析为： <a class="submenu" href='products/6'>
Furthermore, there are some shortcuts you can take here which will help you in the long run. 此外，您可以在此处采取一些捷径，从长远来看将为您提供帮助。
- Instead of
<?php echo "something" ?>turn on php short tags in php.ini and use<?= "something" ?>代替<?php echo "something" ?>打开php.ini中的php short标签，并使用<?= "something" ?> - You don't need to call
base_urlevery time you write a link.您无需在每次编写base_url都调用base_url。 Use the<base>HTML tag appropriately:<base href="http://localhost/yourapp/">in<head>适当使用<base>HTML标记：<head><base href="http://localhost/yourapp/"><head>
So... with that said after using 1 and 2: 所以...使用1和2之后说
<a href='products/<?= $id;?>'><?= $name_of_product ?></a>
