任何一种语言都有专门针对中文处理的函数,往往这些处理方法都是比较难掌握的一部分。今天我们就向大家具体讲一下有关截取GB2312中文字符串
<ol class="dp-xml"> <li class="alt"><span><span class="tag"><span> ?php </span></span></span></li> <li><span>//截取中文字符串 </span></li> <li class="alt"><span>function mysubstr($str, $start, $len) { </span></li> <li> <span> $</span><span class="attribute">tmpstr</span><span> = </span><span class="attribute-value">""</span><span>; </span> </li> <li class="alt"> <span> $</span><span class="attribute">strlen</span><span> = $start + $len; </span> </li> <li> <span> for($</span><span class="attribute">i</span><span> = </span><span class="attribute-value">0</span><span>; $i </span><span class="tag"><span> $strlen; $i++) { </span></span> </li> <li class="alt"> <span> if(ord(substr($str, $i, 1)) </span><span class="tag">></span><span> 0xa0) { </span> </li> <li> <span> $tmpstr </span><span class="attribute">.</span><span>= </span><span class="attribute-value">substr</span><span>($str, $i, 2); </span> </li> <li class="alt"><span> $i++; </span></li> <li><span> } else </span></li> <li class="alt"> <span> $tmpstr </span><span class="attribute">.</span><span>= </span><span class="attribute-value">substr</span><span>($str, $i, 1); </span> </li> <li><span> } </span></li> <li class="alt"><span> return $tmpstr; </span></li> <li><span>} </span></li> <li class="alt"> <span class="tag">?></span><span> </span> </li> </ol>
以上代码示例就是PHP截取中文字符串的相关实现方式。
