Question

How to escape string in JSON? Seems that JSON will escape back slashes.
How do I json_encode(array('name'=>'what\'s the name'))?

Answer 1

Well firstly, you can start by doing this:

json_encode(array("name" => "what's the name"));

PHP, Python, Javascript, etc. all allow the use of both single- and double-quotes for just such an occasion. Use them!

Secondly, the way you want to do this is probably not just ', but \', which means you actually need \\\'. Try this:

json_encode(array('name'=>'what\\\'s the name'));

Thirdly, since you’re getting the information from $_POST, the string is already known-good. Simply:

array_push($info, array('name'=>$_POST['name']));
json_encode($info);
