Why does _GET in PHP wrongly decodes slash?
- by Boaz
Hi,
Today I run into some oddity with PHP, which I fail find a proper explanation for in the documentation. Consider the following code:
<?php
echo $_GET['t']. PHP_EOL;
?>
The code is simple - it takes a single t parameter on the url and outputs it back. So if you call it with test.php?t=%5Ca (%5c is a '\'), I expected to see:
\a
However, this is what I got:
$ curl http://localhost/~boaz/test.php?t=%5Ca
\\a
Notice the double slash. Can anyone explains what's going on and give recipe for retrieving the strings as it was supplied on the URL?
Thanks,
Boaz
