PHP function library provides functions for encoding/decoding JSON: json_encode() and json_decode(), which can more conveniently pass arrays or objects to javascript

Because of the requirements of the interface party, use js to process data , so the PHP program needs to retrieve the value from the database and assign it to the JS array. I haven't found a good way yet, because the data encoding of PHP arrays is different from the encoding format of JS arrays and cannot be output directly.

After searching on the Internet, I found the solution:

The PHP function library provides a function for encoding/decoding JSON: json_encode( ) and json_decode(), which can more conveniently pass arrays or objects to javascript. Note: The JSON extension is only bound to PHP 5.2 and above.

Write as follows in php:

The code is as follows:

$arr = array('1',array('2','3'),array('new','old')); $new_arr = json_encode($arr);//new_arr的输出结果是;["1",["2","3"],["new","old"]] echo "var data =". $new_arr;
Copy after login

After referencing the above php file in the page, directly in js Data can be manipulated.
