json_encode和JSON.parse不协调

Question

I get this output on my php page with json_encode

{"id":"761","user":"Moderator","message":"test"} 
{"id":"760","user":"Patrick","message":"test"}

Now i want to parse theses values with JSON.parse in javascript, to get an array. But it does not work.

It works only if i have one json Objekt.

What is the best way to solve this?

To split at '}' and parse every string that i will get?

Answer 1

{}{} is not valid JSON. You need to have an array wrap these and separate them with commas like [{},{}] . You can do this in PHP via:

$entries = array();
foreach ($database_entry as $array) {
    $entries[] = $array;
}
echo json_encode($entries);

That is you should only call json_encode once .

Answer 2

This output is not a proper JSON object or array. What you want to do is wrap your objects in square brackets, and separate them with commas. The output should look like this:

[{"id":"761","user":"Moderator","message":"test"}, 
{"id":"760","user":"Patrick","message":"test"}]

You will need to change your PHP to generate the output in this way.

Answer 3

JSON.parse applies only strings:

JSON.parse(text[, reviver])

text is the string to parse as JSON. See the JSON object for a description of JSON syntax. MDN .

Answer 4

You'll need to output the objects into a JSON array, with each object/array item separated by a comma:

{ 
  "users": [
      {"id":"761","user":"Moderator","message":"test"}, 
      {"id":"760","user":"Patrick","message":"test"}
  ]
}
