PHP generates nested JSON solution ideas

PHP generates nested JSON

({

"AA": [

{

"Id": "0",

"title": "Titles",

},

{

"Id": "1",

"title": "Titles",

}

],

"BB": [

{

...

},

{

....

}

]

})

How PHP generates this nested JSON

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

/** JSON data format

* @param Mixed $data data

* @param String $indent indent characters, default 4 spaces

* @return JSON

*/

function Jsonformat ($data, $indent =null) {

Each element in the array is recursively urlencode to protect the Chinese character

Array_walk_recursive ($data, ' jsonformatprotect ');

JSON encode

$data = Json_encode ($data);

UrlDecode the contents of the UrlEncode

$data = UrlDecode ($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;

}

/** the array elements to UrlEncode

* @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 (

' AA ' => array (

Array

' Id ' => 0,

' title ' => ' titles '

), array (' ID ' => 1, ' title ' => ' caption '), ' BB ' => Array (array (' ID ' => 2, ' title ' => ' title '), Array ( ' Id ' => 3, ' title ' => ']); Echo Jsonformat ($arr); {"AA": [{"Id": "0", "title": "title"}, {"id": "1", "title": "title"}, "BB": [{"Id": "2", "title": "title"}, {"id": "3", "title": "title"}]}
