PHP JSON Chinese garbled solution encyclopedia

We know that in the use of AJAX technology and PHP background interaction, the Chinese garbled is often the case, JSON as a similar to XML data Interchange Format, in PHP for interaction will also appear in Chinese garbled situation, to solve the PHP JSON Chinese garbled method of thinking in fact, and PHP Ajax to pass the value of character garbled solution similar to the following I take the form of a tutorial in detail to solve the PHP JSON Chinese garbled method.

　　Why does PHP have Chinese garbled characters when interacting with JSON?

Because JSON is the same as JS, the characters for the client are processed in UTF8 form, that is, JSON submits or accepts the returned characters as UTF8, and when interacting with PHP, if the database Code, PHP page encoding is not in UTF8 format, When PHP interacts with JSON, it will produce garbled characters.

　　Ways to solve PHP json Chinese garbled

In the knowledge of the PHP and JSON interaction between the reasons for the Chinese garbled solution is actually a lot simpler.

　　To solve the PHP JSON Chinese garbled method one: To ensure that the database, front and back PHP page code consistent

The simplest way to solve the PHP JSON Chinese garbled method is to ensure that the database code, PHP page encoding unified using UTF8 format, for the PHP beginners to build a station when the database is best to use the UTF8 format, can reduce a lot of trouble.

Commonly used functions have iconv, because iconv need PHP configuration environment support, if not supported, you can write GBK and UTF8 code conversion function to achieve the code conversion, specific reference to PHP Ajax transfer values in the text character garbled solution tutorial.

At this point, PHP JSON characters garbled three kinds of solutions are introduced, in fact, in PHP development, encountered similar to PHP and Ajax/js interaction, the production of Chinese garbled when the basic use of these methods, the idea is similar.
