Hello, I have a JSON string and I want to parse it to an object (to do some query after that). This is user specified.īitmask of JSON decode. Let's start with writing a JSON collection to a file using streams. To handle such large files in a memory-efficient way, we need to work with smaller chunks at a time. We’ll create two instance variables for the book’s instance and encode the object using jsonencode ().

Syntax: json_decode(json_string, assoc, depth, options)Ī JSON encoded string.
