PHP获取汉字拼音首字母的方法

gena2.0

PHP获取汉字拼音首字母的方。封装PHP函数,如果只想获得中文字符串第一个字的拼音首字母,见方法:

function pinyin1($zh){
$ret = "";
    $s1 = iconv("UTF-8","gb2312", $zh);
    $s2 = iconv("gb2312","UTF-8", $s1);
    if($s2 == $zh){$zh = $s1;}
 
    $s1 = substr($zh,$i,1);
    $p = ord($s1);
    if($p > 160){
        $s2 = substr($zh,$i++,2);
        $ret .= getfirstchar($s2);
    }else{
        $ret .= $s1;
    }
return $ret;
}

结果如下:
这是中文字符串:Z
测试:C
你好:N
Cf:C
第i:D
李四:L
显卡:X

取每个汉字的拼音首字母方法:

function getfirstchar($s0){   
	$fchar = ord($s0{0});
	if($fchar >= ord("A") and $fchar < = ord("z") )return strtoupper($s0{0});
	$s1 = iconv("UTF-8","gb2312", $s0);
	$s2 = iconv("gb2312","UTF-8", $s1);
	if($s2 == $s0){$s = $s1;}else{$s = $s0;}
	$asc = ord($s{0}) * 256 + ord($s{1}) - 65536;
	if($asc >= -20319 and $asc < = -20284) return "A";
	if($asc >= -20283 and $asc < = -19776) return "B";
	if($asc >= -19775 and $asc < = -19219) return "C";
	if($asc >= -19218 and $asc < = -18711) return "D";
	if($asc >= -18710 and $asc < = -18527) return "E";
	if($asc >= -18526 and $asc < = -18240) return "F";
	if($asc >= -18239 and $asc < = -17923) return "G";
	if($asc >= -17922 and $asc < = -17418) return "I";
	if($asc >= -17417 and $asc < = -16475) return "J";
	if($asc >= -16474 and $asc < = -16213) return "K";
	if($asc >= -16212 and $asc < = -15641) return "L";
	if($asc >= -15640 and $asc < = -15166) return "M";
	if($asc >= -15165 and $asc < = -14923) return "N";
	if($asc >= -14922 and $asc < = -14915) return "O";
	if($asc >= -14914 and $asc < = -14631) return "P";
	if($asc >= -14630 and $asc < = -14150) return "Q";
	if($asc >= -14149 and $asc < = -14091) return "R";
	if($asc >= -14090 and $asc < = -13319) return "S";
	if($asc >= -13318 and $asc < = -12839) return "T";
	if($asc >= -12838 and $asc < = -12557) return "W";
	if($asc >= -12556 and $asc < = -11848) return "X";
	if($asc >= -11847 and $asc < = -11056) return "Y";
	if($asc >= -11055 and $asc < = -10247) return "Z";
	return null;
}

function pinyin1($zh){
	$ret = "";
    $s1 = iconv("UTF-8","gb2312", $zh);
    $s2 = iconv("gb2312","UTF-8", $s1);
    if($s2 == $zh){$zh = $s1;}
	for($i = 0; $i < strlen($zh); $i++){ 		
		$s1 = substr($zh,$i,1); 		
		$p = ord($s1); 		
		if($p > 160){
			$s2 = substr($zh,$i++,2);
			$ret .= getfirstchar($s2);
		}else{
			$ret .= $s1;
		}
        //echo $ret."<br/>";
	}
	return $ret;
}
echo "这是中文字符串:";
echo pinyin1('这是中文字符串').<br/>"";
$a = array("测试","这","Af","第i","李四","显卡");
foreach($a as $v){
    echo $v.":".pinyin1($v).<br/>"";
}

结果如下:
这是中文字符串:ZSZWZFC
测试:CS
这:Z
Af:Af
第i:Di
李四:LS
显卡:XK
