How to convert Chinese characters to Pinyin in PHP program_PHP tutorial
In order to do a pinyin keyword search in the database, I thought of generating pinyin of the product name as a keyword and storing it in the database, so I collected information online and came up with something like this
/**
* Chinese Pinyin conversion class
* @author julian.song
* Some code sources are from the Internet, and the copyright belongs to the original author
*/
class Pinyin{
Public function __construct()
{
}
/**
* Convert string to Pinyin
* @param $string ASCII code
* @param $charset encoding
*/
Public function getPinyin($string, $charset='gb2312')
{
