php的漢字轉換： Unicode(UTF8)->GBK (轉)

php的漢字轉換： Unicode(UTF8)->GBK (轉)[@more@]

秋水無恨 GBK Unicode UTF8 漢字 轉換

的漢字轉換一直是比較麻煩的事

該類內建了四個過濾"[dec];","[hex];","%u[hex]","utf8轉換"
方便的使用，同時也可自定義過濾進行自己喜歡的操作

qswhU.php 從這裡

使用範例

$qswh=new qswhU("qswhU.php");//如果名是qswhU.php,可省引數
echo "

不帶引數(預設過濾為：[num];):&quot;;<br>echo &quot;n&quot;.$qswh-&gt;decode(&quot;中文Abc&quot;);<br>echo &quot;n&quot;.$qswh-&gt;decode(&quot;中文Abc&quot;);<br>echo &quot;n內建過濾(UTF轉碼):&quot;.$qswh-&gt;decode(&quot;%E4%B8%AD%E6%96%87%20!%22%23%24%25%26'()*%2B%2C%2F%3A%3B%3C%3D%3E%3F%40%5B%5D%5E%60%7B%7C%7D~%25Abc&quot;,1);<br>echo &quot;n呼叫內建過濾unescape(%u[num]):&quot;.$qswh-&gt;decode(&quot;%u4E2D%u6587Abc&quot;,2);<br>echo &quot;n自定義過濾([x+num]):&quot;.$qswh-&gt;decode(&quot;[x4E2D][x6587][x41][x62][x63]&quot;,&quot;/[(w+)]/&quot;); <p>效果如下：<br>不帶引數(預設過濾為：[num];):<br>中文Abc<br>中文Abc<br>呼叫內建過濾(UTF轉碼):中文 !&quot;#$%&amp;'()*+,/:;&lt;=&gt;?@[]^`{|}~%Abc<br>呼叫內建過濾unescape(%u[num]):中文Abc<br>自定義過濾([x+num]):中文Abc</p> <p><br>ps.該文章現僅限在csdn文件中心，如要轉載，請和作者聯絡，否則後果自負。</p><br>
