Json Array problems, online, etc.

Json Array problems, online and other json Array problems, as an interface to output json, online, etc.
There are two arrays $ result1 and $ result2. when the json Array is output, echo json_encode ($ result1); echo json_encode ($ result2); can two arrays be output in this way? It seems that only one output is allowed. how to combine the two into one and output echo json_encode ($ result );

Reply to discussion (solution)

Echo json_encode (array ($ result1, $ result2 ));

Echo json_encode (array ('result1' => $ result1, 'result2' => $ result2 ));

Same as above. you can concatenate two arrays into one and separate them on the browser end.

Combination first? One ???, Then in? Line json_encode
$ Result = array ($ result1, $ result2 );
Echo json_encode ($ result );
