Scenario/problem description:

The Ajax submission page is encoded as gb2312, and the database is encoded as utf8. Data is inserted without modifying the page and database encoding.

Custom functions:

The code is as follows: Copy code
Function array_iconv ($ in_charset, $ out_charset, $ arr ){
Return eval ('Return '. iconv ($ in_charset, $ out_charset, var_export ($ arr, true ).';'));

Function description:
Var_export sets the second parameter to true, returns the array prototype string, converts the string to UTF-8 encoding, and then uses eval to execute the return.

Example:

The code is as follows: Copy code
$ Postdata =$ _ POST;
$ Data = array_iconv ('gb2312', 'utf-8', $ postdata)
Print_r ($ data );

With the Firefox firebug component, we can see that:

Let's look at the Database again:

 

We can see that the encoding is normal and the database is successfully imported.
