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><span> ?php </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><span> $strlen; $i++) { </span></li><li class="alt"><span> if(ord(substr($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。
