Just do json Encode using Php function json_encode()

$json=json_encode($json_array);

Just create the data structure you want with php arrays and then json_encode($data);

If you want an additional array wrapper: (I'm using the more modern array syntax)

$data = [[ //or array(array( "dir"=>$tmp[0], "sym"=>$tmp[1], "bid"=>$tmp[2], "ask"=>$tmp[3] ]]; // or )) $data = json_encode($data);

Also don't forget to first set your content type header: header('Content-type: application/json');

You need to json_enoce of your array:

$json_array=array( "dir"=>$tmp[0], "sym"=>$tmp[1], "bid"=>$tmp[2], "ask"=>$tmp[3] ); print_r(json_encode($json_array));

It will print the JSON representation of $json_array

$json_array=array(); json_object1=array( "dir"=>$tmp[0], "sym"=>$tmp[1], "bid"=>$tmp[2], "ask"=>$tmp[3] ); $json_array[]=json_object1; $json_object2=array( "dir"=>$tmp[0], "sym"=>$tmp[1], "bid"=>$tmp[2], "ask"=>$tmp[3] ); $json_array[]=json_object2; json_encode($json_array);

Use Json Encode to convert it to a PHP.

$data = array( "dir"=>$tmp[0], "sym"=>$tmp[1], "bid"=>$tmp[2], "ask"=>$tmp[3] ); echo json_encode($data);

Try this .

$json_array=array( "dir"=>$tmp[0], "sym"=>$tmp[1], "bid"=>$tmp[2], "ask"=>$tmp[3] ); echo json_encode(array($json_array));

Output :

[{"dir":null,"sym":null,"bid":null,"ask":null}]
