使用if、elseif及else,不进判定直接输出else里的,是数据库表头类型难点要么语句错误?

在向来不现身emoji字符在此以前,算字符串的尺寸就很简短,直接遍历字符串,找寻个中的国语和别的字符一贯算出长度就能够。可是现身emoji之后,就从未有过那么轻巧了。

运用if、elseif及else,不进决断直接输出else里的,是数据库表头类型难题还是语句错误?

意气风发:先介绍多少个基本概念:

企望各位能付与支持!

1
编码:Computer内部无法储存字符,只好存款和储蓄数字,数字与字符或标记的对待表,就是编码(比方ascll编码)

以下是语句:

$sql="select * from `shipin` where id =".$zyid;$result=mysql_query($sql,$conn);$shipin=mysql_fetch_array;$sql="select * from `peizhi` where id =1";$user=queryall(user,$type);$peizhi=queryall(peizhi,"where id='1'");$totalMoney=$ubomoney;if($peizhi[al]>0){if(($peizhi[al]=="1")or($user[al]=="1")){ if{ $shipin=queryall(shipin,"where id='$zyid'"); if(intval($shipin[al])){ $totalMoney=$shipin[al];//金额 自定义 } }}elseif(($peizhi[al]=="2")or($user[al]=="2")){ $shipin=queryall(shipin,"where id='$zyid'"); if($shipin['is_lei']==1){ $totalMoney=$ubomoney*100;//金额 百倍 } }}else{ $shipin=queryall(shipin,"where id='$zyid'"); $totalMoney=$ubomoney;//正常} 

*$peizhi[al]是总按键,设置0/54%个别为正规、自定义、百倍。

$user[al]是单独主宰开关,设置0/51%分头为正规、自定义、百倍。*

施行的话不走if($peizhi[al]>0 里的判别··而是直接走else的。怎么破?

2 UTF :即Unicode Transformation formats (Unicode
调换格式),一个字符恐怕适合用Unicode表示的数字。(UTF8
是八个字符用8位表示,32即三十几人代表)

以下数据库详细情况:

peizhi表:
必威官网手机版 1

shipin表:
必威官网手机版 2

user表:
必威官网手机版 3

3 码点,码元:Unicode
差十分的少为世界上每后生可畏种字符恐怕符号定义了唯豆蔻梢头的一个数字,即码点;叁个码点不常候对应四个码元,不经常候多少个。多少个合起来的码元对应叁个码元即代理对。

4 nsstring 与 Unicode:nsstring 的length是字符串中隐含的码元个数。

5 nsstring
字符串中大概带有组合字符种类、代理对、变体字符体系,所以length的长度并非您看看的。

二:判定汉字和emoj的办法

1 决断汉字

  • (BOOL)isChineseChar:(int)ch

{

if( ch >=0x4e00 && ch <0x9fa5){

returnYES;

}else{

returnNO;

}

}

2 判断emoji

– (BOOL)isEmoji:(NSString*)substring

{

BOOLreturnValue =NO;

constunicharhs = [substringcharacterAtIndex:0];

// surrogate pair

if(0xd800<= hs && hs <=0xdbff) {

if(substring.length>1) {

constunicharls = [substringcharacterAtIndex:1];

constintuc = ((hs -0xd800) *0x400) + (ls -0xdc00) +0x10000;

if(0x1d000<= uc && uc <=0x1f9c0) {

returnValue =YES;

}

}

}elseif(substring.length>1) {

constunicharls = [substringcharacterAtIndex:1];

if(ls ==0x20e3) {

returnValue =YES;

}

}else{

// non surrogate

if(0x2100<= hs && hs <=0x27ff) {

returnValue =YES;

}elseif(0x2B05<= hs && hs <=0x2b07) {

returnValue =YES;

}elseif(0x2934<= hs && hs <=0x2935) {

returnValue =YES;

}elseif(0x3297<= hs && hs <=0x3299) {

returnValue =YES;

}elseif(hs ==0xa9|| hs ==0xae|| hs ==0x303d|| hs ==0x3030|| hs
==0x2b55|| hs ==0x2b1c|| hs ==0x2b1b|| hs ==0x2b50) {

returnValue =YES;

}

}

return returnValue;

}

有关此外的字符小编都归为黄金时代类了。

计量字符的长短

– (NSInteger)numberOfString:(NSString*)str

{

if(![str isNotEmpty])

{

return0;

}

__block NSInteger characterNum =0;

[str enumerateSubstringsInRange:NSMakeRange(0, str.length)

options:NSStringEnumerationByComposedCharacterSequences

usingBlock:^(NSString*_Nullablesubstring,NSRangesubstringRange,NSRangeenclosingRange,BOOL*_Nonnullstop)
{

if([[selfclass]isChineseChar:[substring characterAtIndex:0]])

{

characterNum +=2;

}elseif([self isEmoji:substring])

{

characterNum +=2;

}else

{

characterNum ++;

}

}];

returncharacterNum;

}
