如何在URL中传递斜杠/？

Question

On this page there are many abbreviation / acronym entries: http://abbreviations.wordcrow.com/acronyms/D/

They are generated in PHP:

<a href="/define/<?php echo rawurlencode($abbreviation['title'])?>/">
    <strong><?php echo $abbreviation['title']?></strong>
</a>

I used rawurlencode because many acronyms contain bizarre characters such as #, & and even /.

And the URL requests such as:

http://abbreviations.wordcrow.com/define/DA%26E/

Would first be fed to rawurldecode():

$acronym = rawurldecode('DA%26E'); // $acronym would be 'DA&E'.

And then used in database queries.

While DA&E is all right, DA/C is not. Try this URL http://abbreviations.wordcrow.com/define/DA%2FC/ and you would end up with http://abbreviations.wordcrow.com/define/DA/C/ which is an error page.

I can extend more code to recognize /define/DA/C/ but it's just weird and non-sensible. I tried both Chrome and Firefox and they all automatically convert DA%2FC to DA/C. But with DA%26E, they don't.

What am I doing wrong?

While you need to do what you need to do -

An option i finally used when AllowEncodedSlashes On didn't work was found here... (using slugs) - not only faster on the lookup/creation of them, but it [main point] solved my situation faster and had more 'url juice' :).

Found originally here:

Used the modified here [used in my own files]:
