How does PHP generate such nested JSON

------ Solution --------------------

/** Format Json data

* @ Param Mixed $ data

* @ Param String $ indent character. the default value is 4 spaces.

* @ Return JSON

*/

Function jsonFormat ($ data, $ indent = null ){

// Recursive urlencode operation on each element in the array to protect Chinese characters

Array_pai_recursive ($ data, 'jsonformatprotect ');

// Json encode

$ Data = json_encode ($ data );

// Urlencode the content in urldecode

$ Data = urldecode ($ data );

// Indent processing

$ Ret = '';

$ Pos = 0;

$ Length = strlen ($ data );

$ Indent = isset ($ indent )? $ Indent :'';

$ Newline = "\ n ";

$ Prevchar = '';

$ Outofquotes = true;

For ($ I = 0; $ I <= $ length; $ I ++ ){

$ Char = substr ($ data, $ I, 1 );

If ($ char = '"' & $ prevchar! = '\\'){

$ Outofquotes =! $ Outofquotes;

} Elseif ($ char = '}' ------ solution -------------------- $ char = ']') & $ outofquotes ){

$ Ret. = $ newline;

$ Pos --;

For ($ j = 0; $ j <$ pos; $ j ++ ){

$ Ret. = $ indent;

}

}

$ Ret. = $ char;

If ($ char = ',' ------ solution ------------------ $ char = '{' ------ solution -------------------- $ char = '[') & $ outofquotes ){

$ Ret. = $ newline;

If ($ char = '{' ------ solution ------------------ $ char = '['){

$ Pos ++;

}

For ($ j = 0; $ j <$ pos; $ j ++ ){

$ Ret. = $ indent;

}

}

$ Prevchar = $ char;

}

Return $ ret;

}

/** Urlencode the array element

* @ Param String $ val

*/

Function jsonFormatProtect (& $ val ){

If ($ val! = True & $ val! = False & $ val! = Null ){

$ Val = urlencode ($ val );

}

}

Header ('content-type: application/json; charset = utf8 ');

$ Arr = array (

'A' => array (

Array (

'Id' => 0,

'Title' => 'title'

), Array ('id' => 1, 'title' => 'title'),), 'BB '=> array ('id' => 2, 'title' => 'title'), array ('id' => 3, 'title' => 'title'),); echo jsonFormat ($ arr ); {"aa": [{"Id": "0", "title": "title" },{ "Id": "1", "title ": "title"}], "bb": [{"Id": "2", "title": "title" },{ "Id": "3 ", "title": "title"}]}
