Recover plain text from a string which is a result of base64 decoding a plain text itself

I made an ajax request to my server and sent some data(plain text) as a query string variable. I saved that data into a text file after using base64_decode() function in php which obviously saves gibberish.

Now I want to recover the plain text from the gibberish data saved in my text file. How do I do that?

Any help appreciated
test.php

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
data = '12345';
$.ajax({url:'sample.php?data='+data,success:function(){}});
</script>

sample.php

<?php

file_put_contents('file.txt','data='.base64_decode($_REQUEST['data'])."\r    \n",FILE_APPEND);

?>

`base64_encode`? – Musa Jul 03 '18 at 12:19
I decoded the plain text. Not encoded anything – Alisa Darya Jul 03 '18 at 12:26
original data -> base64_decode -> new data -> base64_encode -> original data – Musa Jul 03 '18 at 12:33
Make sure you're explicit with your character encoding on both the encode and decode operations. – Pseudonymous Jul 03 '18 at 15:03
@Musa encoding the new data doesnt return the original data – Alisa Darya Jul 04 '18 at 04:04
Let's see some code, example data etc – Musa Jul 04 '18 at 04:10

You have an example data set as `12345` which in not base64 encoded, so why are you decoding it? – Musa Jul 04 '18 at 12:09
See. I accidentally decoded the plain text. But now I want to recover that text from the gibberish data that got saved in my text fle – Alisa Darya Jul 05 '18 at 09:11
