如何将数组转换为包含PHP中的双引号的json？

Question

I want to convert an array into JSON. My problem is that one of that elements in that array contain single quotes, double quotes etc.

<textarea name="description" id="description">
   Tesla is the living definition of bad*** and mad scientist. 
   During Tesla's later years, he made claims concerning a 
   "teleforce" weapon after studying the Van de Graaff generator. 
   The press called it a "peace ray" or death ray. Tesla described 
   the weapon as being able to be used against ground-based infantry 
   or for antiaircraft purposes.
</textarea>

When I submit it I got:

$description = $_POST['description'];
json_encode($description);

When I decode it, I got only a part of string.

Answer 1

Or maybe you could try with addcslashes, which is more adapted (you can define a list of parameters to escape).
