Encoder Url Online

In Java, I want to convert this:

https%3A%2F%2Fmywebsite%2Fdocs%2Fenglish%2Fsite%2Fmybook.do%3Frequest_type

To this:

https://mywebsite/docs/english/site/mybook.do&request_type

This is what I have so far:

class StringUTF {    public static void main(String[] args)     {        try{            String url =                "https%3A%2F%2Fmywebsite%2Fdocs%2Fenglish%2Fsite%2Fmybook.do" +               "%3Frequest_type%3D%26type%3Dprivate";            System.out.println(url+"Hello World!------->" +                new String(url.getBytes("UTF-8"),"ASCII"));        }        catch(Exception E){        }    }}

But it doesn't work right. What are these %3A and %2F formats called and how do I convert them?

I want to create a search which searches some other website from my website,The problem is that other website is uses - instead of + for example: https://somewebsite.com/?search=example-search-query but when I use this code:

<form class="example" method="get" action="https://europixhd.io/svop2/zznewsrv4" style="margin:auto;max-width:300px">  <input type="text" placeholder="Movie Name Here..." name="search">  <button type="submit"><i class="fa fa-play"></i></button></form>

It of course adds a + instead of a -any help would be appreciated, Thanks!

I have no problem using one or the other... I'm more curious about the history / rationale behind it.

I mean, why use + when all other ASCII characters where addressed with the %HH notation?

I'm guessing there might have been some some legacy reason behind it which would be neat to know. Lord knows I've written enough stuff shortsightedly that still has some reverse compatible functionality in production years later. If I had to guess, I'd say it was probably an early mechanism to support spaces in file/folder names and then the %HH took over, while leaving + supported. However, I'm usually wrong.

I'm unsure of the terminology for all of this so please bare with me

I have just created an HTML or URL link for multiple URLs, however, it is not compatible with mobile phones. Is there any coding that I can put into the HTML to make it compatible?THanks

I'm trying to get the format of Date/Time from the URL with the $_GET and put it into a input field:

This is the format: 09/11/2019 14:48 CDT 09/11/2019 14:48 CDT

$stime = "09/11/2019 14:48 CDT 09/11/2019 14:48 CDT";$etime = "";

This is part of the code when the form is submitted:

includes/connect.inc.php

    if (empty($stime) || empty($etime)) {            header("Location: ../home.php?error=emptyfields&stime=".rawurlencode($stime)."");            exit();}

This is the code where the form/input fields are:

home.php

if (isset($_GET['error'])) {    $stime = ($_GET['stime']);}else {    $stime = "";}<form method="post" action="includes/connect.inc.php" enctype="multipart/form-data"><li>Start Time : <input type="text" name="stime" id="dato8" value=<?php echo rawurldecode($stime); ?> ></li><input type="submit" value="Submit" class="button"></form>

All works fine but the string that returns to the input field is just: "09/11/2019", missing the rest of the original string.

Any idea of what am i doing wrong?

I did a test in a separate file with this code:

<?php$dateDecoded = "09%2F11%2F2019%2014%3A48%20CDT%2009%2F11%2F2019%2014%3A48%20CDT";$dateToEncode = "09/11/2019 14:48 CDT 09/11/2019 14:48 CDT";echo rawurldecode($dateDecoded);echo "<br>";echo rawurlencode(dateToEncode); ?>

And works perfect, does the result i'm looking for, this is the output of the above test:

09/11/2019 14:48 CDT 09/11/2019 14:48 CDT09%2F11%2F2019%2014%3A48%20CDT%2009%2F11%2F2019%2014%3A48%20CDT

Thanks in advance.
