- json_encode() escaping forward slashes 3 answers
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

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() 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.
