Php code conversion. Encoding and conversion this code is in the ThinkPHP framework and is often used. let's take a look at it separately. Functionauto_charset ($ fContents, $ from, $ to) {if (str encoding and conversion code is in the ThinkPHP framework. it feels very common, so let's take it out separately. let's take a look.

Function auto_charset ($ fContents, $ from = '', $ to = '')
{

// If the encoding is the same or the non-string scalar, the conversion is not performed.

$ To = strtoupper ($ to) = 'utf8 '? 'Utf-8': $;
If (is_string ($ fContents )){
If (function_exists ('MB _ convert_encoding ')){
Return mb_convert_encoding ($ fContents, $ to, $ from );
