Php array conversion js array operations and usage of json_encode

Php array conversion js array operation and json_encode usage. For more information, see JSON.

For php, I personally feel that I am familiar with array and string operations. php itself has a lot of functions for operating arrays and strings. today, when I create a function, the store information needs to be dynamically created using Js. This information needs to be added from the backend. if you want to use php to read the database, obtain the array, and then convert the array into a js array as required,
Php array format:
The code is as follows:
$ NewArray = array ('region' => 'Beijing', 'items '=> '10 ', 'detail' => array (0 => array ('shop name' => 'flagship Store ', 'URL' => 'http: // www. '), 1 => array ('shop name' => 'jjjj', 'URL' => 'http: // www. fdd '))),
Array ('region' => 'Shanghai', 'items '=> '11 ', 'detail' => array (0 => array ('shop name' => 'flagship Store ', 'URL' => 'http: // www. '), 1 => array ('shop name' => 'jjjj', 'URL' => 'http: // www. fdd '))),
);

A very convenient function is used here: json_encode ();
Var jsarray = new Array ();
Jsarray = ;
Use console. log (); to view the jsarray structure.

How to construct such a qualified php array here? (I am using a phpcms system)
The code is as follows:
$ SQL = 'SELECT catid, catname, items from category where parentid = 10 ';
$ Result = mysql_query ($ SQL );
While ($ row = mysql_fetch_array ($ result )){
$ ArrArea ['region'] = $ row ['catname'];
$ ArrArea ['items '] = $ row ['items'];
Unset ($ arrArea ['detail']); // This step is critical. Otherwise, the information will be accumulated.
$ Sql2 = 'SELECT title, url from news where catid = '. $ row ['catid'];
$ Fendian = mysql_query ($ sql2 );
While ($ re = mysql_fetch_assoc ($ fendian )){
$ Item ['shop name'] = $ re ['title'];
$ Item ['URL'] = $ re ['URL'];
$ ArrArea ['detail'] [] = $ item;
}
$ Newwarr [] = $ arrArea;
}
Var_dump ($ newwarr );

Json_encode: JSON encoding of the variable, which can only accept data encoded by the UTF-8.

Corresponding to json_decode, the second parameter is true, returns an array, and executes the inverse process.

Json can only use objects and arrays.
