This article describes how to implement php recursive json classes. Share it with you for your reference.

The specific implementation code is as follows:

Copy codeThe Code is as follows: <? Php
/*

Class json {
Private $ Arr = array (); // input an array
// Constructor
Public function json ($ array)
{

}
// Parse the main function
Public function MainArr ()

}
Else
{

}
Return $ json;
}
// Parse the Index Array
