I am storing my data in the form of json to the database. User can input with quotes, so i am manually adding slashes before the quotes. So my data becomes like this

array:8 [▼ "buttonText" => "Large Button" "campName" => "Large\'s Button Test" "buttonSize" => "1" ]

But when i am converting it into json, the json_encode() function automatically added one more slash before my slash as

"{"buttonText":"Large Button","campName":"Large\\'s Button Test","buttonSize":"1"}"

Why the extra slash will be added, is there any option to prevent that

  • please provide more code. what you are experiencing usually happens due to implementing the json encode functions twice Commented Jun 27, 2017 at 7:26

    I can't think of any scenario where you need to add slashes manually. I have the impression that you're trying to prevent SQL injection but you're instead corrupting data. Commented Jun 27, 2017 at 7:28

    If you want to encode a value with a backslash, the correct JSON encoding for that is a doubled backslash. Why are you adding backslashes to your data in the first place?! Commented Jun 27, 2017 at 7:29

    @ravisachaniya — That's about forward slashes, not backslashes. Commented Jun 27, 2017 at 7:30

    "Why the extra slash will be added, is there any option to prevent that?" -- Do you want to prevent what? To prevent json_encode() create a valid JSON? Go ahead and remove the backslashes as you please. You will come back tomorrow with another question complaining that json_decode() cannot decode your malformed JSONs. Commented Jun 27, 2017 at 7:57

Why you do like this? Is totaly bad thing adding slashes manualy.

You can just generate JSON using arrays like:

$arr=array(); $arr['buttonText']="Large Button"; $arr['campName']="Large's Button Test"; $arr['buttonSize']=1; echo json_encode($arr);

Just use json_encode() to store values and json_decode() to get values.

Here is diferent aproach:

$arr=array( 'buttonText'=>"Large Button", 'campName'=>"Large's Button Test", 'buttonSize'=>1, ); echo json_encode($arr);

JSON ENCODE - Manual

JSON DECODE - Manual

json_encode() adding slashes automaticaly and json_decode() remove it. You don't need to think about that. Just don't worry and be happy.

Extra slashes are added because that's what json_encode will do. See this documentation

In your case if you're encoding data to store in database, you don't need to manually add slashed. json_encode will take care of all escaping.
