只是需要自己写一个uft8到unicode的转换函数
分类:热门资源

gb2312 和 unicode 间的编码转换 下面的例子是将 gb2312 转换为 ""这种形式 php4.3.1以后的iconv函数很好用的,只是需要自己写一个uft8到unicode的转换函数 查表(gb2312.txt)也行 代码如下: ? $text = "脚本之家"; preg_match_all("/[/x80-/xff]?./",$text,$ar); foreach($ar[0] as $v) echo "".utf8_unicode(iconv("GB2312","UTF-8",$v)).";"; ? ? // utf8 - unicode function utf8_unicode($c) { switch(strlen($c)) { case 1: return ord($c); case 2: $n = (ord($c[0]) & 0x3f) 6; $n += ord($c[1]) & 0x3f; return $n; case 3: $n = (ord($c[0]) & 0x1f) 12; $n += (ord($c[1]) & 0x3f) 6; $n += ord($c[2]) & 0x3f; return $n; case 4: $n = (ord($c[0]) & 0x0f) 18; $n += (ord($c[1]) & 0x3f) 12; $n += (ord($c[2]) & 0x3f) 6; $n += ord($c[3]) & 0x3f; return $n; } } ? 下面的例子是利用php将""这中编码转换为gb2312. 代码如下: ?php $str = "TTL"; $str = preg_replace("|([0-9]{1,5});|", "/".u2utf82gb(//1)./"", $str); $str = "/$str=/"$str/";"; eval($str); echo $str; function u2utf82gb($c){ $str=""; if ($c 0x80) { $str.=$c; } else if ($c 0x800) { $str.=chr(0xC0 | $c6); $str.=chr(0x80 | $c & 0x3F); } else if ($c 0x10000) { $str.=chr(0xE0 | $c12); $str.=chr(0x80 | $c6 & 0x3F); $str.=chr(0x80 | $c & 0x3F); } else if ($c 0x200000) { $str.=chr(0xF0 | $c18); $str.=chr(0x80 | $c12 & 0x3F); $str.=chr(0x80 | $c6 & 0x3F); $str.=chr(0x80 | $c & 0x3F); } return iconv('UTF-8', 'GB2312', $str); } ? 或者是 代码如下: function unescape($str) { $str = rawurldecode($str); preg_match_all("/(?:%u.{4})|.{4};|/d+;|.+/U",$str,$r); $ar = $r[0]; print_r($ar); foreach($ar as $k=$v) { if(substr($v,0,2) == "%u") $ar[$k] = iconv("UCS-2","GB2312",pack("H4",substr($v,-4))); elseif(substr($v,0,3) == "") $ar[$k] = iconv("UCS-2","GB2312",pack("H4",substr($v,3,-1))); elseif(substr($v,0,2) == "") { echo substr($v,2,-1)."br"; $ar[$k] = iconv("UCS-2","GB2312",pack("n",substr($v,2,-1))); } } return join("",$ar); } $str = "TTL"; echo unescape($str); //out TTL全天候自动聚焦 利用javascript来转换 代码如下: style BODY { FONT-SIZE: 9pt; PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; PADDING-TOP: 0px; } input { FONT-SIZE: 9pt; height: 13pt; } /style script language="JavaScript1.2" /* This following code are designed and writen by Windy_sk seasonx@163.net You can use it freely, but u must held all the copyright items! */ function Str2Unicode(str){ var arr = new Array(); for(var i=0;istr.length;i++){ arr[i]="" + str.charCodeAt(i) + ";"; } return(arr.toString().replace(/,/g,"")); } function Unicode2oStr(str){ var re=/[/da-fA-F]{1,5};/ig; var arr=str.match(re); if(arr==null)return(""); for(var i=0;iarr.length;i++){ arr[i]=String.fromCharCode(arr[i].replace(/[]/g,"")); } return(arr.toString().replace(/,/g,"")) } function modi_str(){ if(document.all.text.method.checked){ if(document.all.text.decode.value!=""){ document.all.text.encode.value = Str2Unicode(document.all.text.decode.value); }else{ document.all.text.decode.value = Unicode2oStr(document.all.text.encode.value); } }else{ if(document.all.text.encode.value!=""){ document.all.text.decode.value = Unicode2oStr(document.all.text.encode.value); }else{ document.all.text.encode.value = Str2Unicode(document.all.text.decode.value); } } } /script titleUnicode/title form name=text 文本原型:br textarea name="decode" cols="100" rows="10"/textarea br 转换代码:br textarea name="encode" cols="100" rows="10"/textarea br input type="checkbox" name="method" checked 正向转换 input type=button onclick="modi_str()" value=" 确 定 " input type=reset value=" 清 空 " input type=button onclick="document.all.text.method.checked?document.all.text.encode.select():document.all.text.decode.select()" value=" 全 选 " /form 下面是一个显示所有全角半角的字体的查看例子 代码如下: style BODY { FONT-SIZE: 9pt; PADDING-RIGHT: 0px; PADDING-LEFT: 0px; PADDING-BOTTOM: 0px; PADDING-TOP: 0px; } input { FONT-SIZE: 9pt; height: 13pt; } /style script function showUni(min,max){ show.document.open(); show.document.writeln("stylebody{font-size:9pt;word-break:break-all;}/style"); show.document.writeln(min + " - " + max + "brbr"); var i=0; for(i=min;i=max;i++){ show.document.write("" + i + ";"); } show.document.close(); } /script input type=button value="半角" onclick=showUni(32,126) input type=button value="全角" onclick=showUni(65281,65374) input type=button value="中文1" onclick=showUni(19968,40869) input type=button value="中文2" onclick=showUni(63744,64045) input type=button value="日文平" onclick=showUni(12353,12435) input type=button value="日文片" onclick=showUni(12449,12534) input type=button value="韩文" onclick=showUni(44032,55203) br自定义:input name=min - input name=max input type=button value="察看" onclick=showUni(parseInt(document.all.min.value),parseInt(document.all.max.value)) br iframe src="about:blank" id=show width=100% height=70% scroll=no/iframe 下面是一个查表(gb2312),转换gb2312到utf8的例子, 现在有iconv函数,这个已经没有太大的意义了, 代码如下: ? function gb2utf8($gb){ if(!trim($gb)) return $gb; $filename="gb2312.txt"; $tmp=file($filename); $codetable=array(); while(list($key,$value)=each($tmp)) $codetable[hexdec(substr($value,0,6))]=substr($value,7,6); $utf8=""; while($gb) { if (ord(substr($gb,0,1))127) { $this=substr($gb,0,2); $gb=substr($gb,2,strlen($gb)-2); $utf8.=u2utf8(hexdec($codetable[hexdec(bin2hex($this))-0x8080])); }else{ $this=substr($gb,0,1); $gb=substr($gb,1,strlen($gb)-1); $utf8.=u2utf8($this); } } return $utf8; } function u2utf8($c){ $str=""; if ($c 0x80) { $str.=$c; } else if ($c 0x800) { $str.=chr(0xC0 | $c6); $str.=chr(0x80 | $c & 0x3F); } else if ($c 0x10000) { $str.=chr(0xE0 | $c12); $str.=chr(0x80 | $c6 & 0x3F); $str.=chr(0x80 | $c & 0x3F); } else if ($c 0x200000) { $str.=chr(0xF0 | $c18); $str.=chr(0x80 | $c12 & 0x3F); $str.=chr(0x80 | $c6 & 0x3F); $str.=chr(0x80 | $c & 0x3F); } return $str; } ?
