Question

PHP:

$var = "Sum Random'z String"s with quotemarks"
$send = base64_encode($var)

Then it sends the base64 encoded string to server.

Server part (Python) tryes to decode the base64-encoded content and write it into file:

f = open("/root/data.yml","w")
f.write(base64.b64decode(sys.argv[1]))
f.close()

sys.argv[1] is $send

However, when i open data.yml in nano or cat, i get this:

Sum Random\'z String\"s with quotemarks

I dont want \ there.
Is there a way so the \ character will not appear there, when i open it in nano or cat? What shall i change?
EDIT:
$var is taken from textarea where there are no \

Answer 1

You don’t need to escape both the single and double quote. You only need to escape what you’re quoting the string with (i.e. ")

$var = "Sum Random'z String\"s with quotemarks";

This may not be your only problem. But it is part of the problem.

UPDATE

Per your update of $var being set with data from a form textarea, you need to look at stripslashes()
