How to fix link output in parsed json?

Question

JSON

json. when displaying information from the database - let's say a picture, the database is stored with all the text, let's say: Hello everyone <img src="images/news/0_180e93_bc8e44dc_orig.jpg"> and everything is fine, but when outputting json information, it gives such a link - < img src="\"/images/news/0_180e93_bc8e44dc_orig.jpg\"">, the same with the video if the html code of the video is copied from YouTube, here's how to fix it \/ "" characters and unnecessary quotes
and immediately another question arose yet one, let's say in the upload file those - url: 'load.php', the information is not immediately taken, but first passes through the variables, those $name =" $soname ";
the question is why does it drop?
