Analysis of the problem in the use of json_encode in php and inarray in jQuery!

If the array is an sequential array and starts from 0, such as:

public static $service_gid = array(11430, 11431, 11432);

Then

Check whether there are special products in the product list, if there is, a dialog box will pop up: Whether you need to arrange after-sales personnel, please select Yes

Now

The array index starts from 0, the generated js array

At this time, through InArray, it will detect whether 11430 is in the array, and it will return 0;

If

public static $service_gid = array(2=>11430, 3=>11431, 4=>11432);

Then

js array returned by php array starting from 2

At this time, through InArray, it will detect whether 11430 is in the array, and it will return -1;

Therefore, it can be explained that there is still a difference between inArray and Array_search in PHP. The array index must start from 0 to retrieve whether it contains this value, otherwise it is not possible!
