On this page there are many abbreviation / acronym entries: http://abbreviations.wordcrow.com/acronyms/D/
They are generated in PHP:
I used rawurlencode because many acronyms contain bizarre characters such as #, & and even /.PHP Code:
<a href="/define/<?php echo rawurlencode($abbreviation['title'])?>/">
<strong><?php echo $abbreviation['title']?></strong>
And the URL requests such as:
Would first be fed to rawurldecode():
And then used in database queries.PHP Code:
$acronym = rawurldecode('DA%26E'); // $acronym would be 'DA&E'.
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? Ain't that / already encoded into '%2F'?? Really weird. Any help would be appreciated!
