JSON format in PHP

Question

{"required_items":[
                   {
                    "filename":"abcd",
                    "no":"3"
                   },
                   {
                    "filename":"abc",
                    "no":"2"
                   }
                  ]}

I am not getting the code of the JSON format in PHP - I want to insert the filename and no through a loop.

Answer 1

Pass the JSON to json_decode and you'll end up with an regular PHP data structure you can operate on. Use var_dump to take a look at it. When you're done manipulating it, turn it back into JSON with json_encode

I don't know if it's typos on your part, but the format you pasted isn't valid JSON.

Answer 2

If you're asking how to generate the above JSON code in PHP, do something like this:

$object->required_items = array();

for( ... your loop here ... )
{
    $item->filename = 'filename';
    $item->no = 1;
    $object->required_items[] = $item;
}

$json = json_encode( $object );
