In reality, we often see such a description, ranking in no order, by name first letter to sort. This is the sort of method most Chinese use. So how do you do it in a PHP program?
The following to share in the PHP program to obtain the first letter of Chinese pinyin method, the most of the online search is problematic, this is a small series of practical application, really can use OH.
PHP gets Chinese character phonetic initials function Getfirstcharter ($STR) {if (empty ($STR)) {return ';}
$fchar =ord ($str {0});
if ($fchar >=ord (' A ') && $fchar <=ord (' z ')) return Strtoupper ($str {0});
$s 1=iconv (' UTF-8 ', ' gb2312 ', $str);
$s 2=iconv (' gb2312 ', ' UTF-8 ', $s 1);
$s = $s 2== $str? $s 1: $str;
$asc =ord ($s {0}) *256+ord ($s {1})-65536;
if ($asc >=-20319&& $asc <=-20284) return ' A ';
if ($asc >=-20283&& $asc <=-19776) return ' B ';
if ($asc >=-19775&& $asc <=-19219) return ' C ';
if ($asc >=-19218&& $asc <=-18711) return ' D ';
if ($asc >=-18710&& $asc <=-18527) return ' E ';
if ($asc >=-18526&& $asc <=-18240) return ' F ';
if ($asc >=-18239&& $asc <=-17923) return ' G ';
if ($asc >=-17922&& $asc <=-17418) return ' H ';
if ($asc >=-17417&& $asc <=-16475) return ' J ';
if ($asc >=-16474&& $asc <=-16213) return ' K ';
if ($asc >=-16212&& $asc <=-15641) return ' L '; if ($asc >=-15640&& $asc <=-15166) return ' M ';
if ($asc >=-15165&& $asc <=-14923) return ' N ';
if ($asc >=-14922&& $asc <=-14915) return ' O ';
if ($asc >=-14914&& $asc <=-14631) return ' P ';
if ($asc >=-14630&& $asc <=-14150) return ' Q ';
if ($asc >=-14149&& $asc <=-14091) return ' R ';
if ($asc >=-14090&& $asc <=-13319) return ' S ';
if ($asc >=-13318&& $asc <=-12839) return ' T ';
if ($asc >=-12838&& $asc <=-12557) return ' W ';
if ($asc >=-12556&& $asc <=-11848) return ' X ';
if ($asc >=-11847&& $asc <=-11056) return ' Y ';
if ($asc >=-11055&& $asc <=-10247) return ' Z ';
return null; }
Examples are as follows:
The above is the PHP to get Chinese characters Pinyin first letter function, hope to be able to help everyone better learning PHP programming.
