• , and when doing actual operations, you often encounter some problems that are not in the books. Only by solving these problems well can we truly master the knowledge we have learned. In this article, you will learn the specific solution to the garbled Chinese characters intercepted by PHP.

  Relevant code for PHP to intercept Chinese characters without garbled characters:

  <ol class="dp-xml">
  <li class="alt"><span><span>function cnSubstr($str, $start, $len) {  </span></span></li>
  <li>
  <span>$</span><span class="attribute">str_tmp</span><span> = $len - $start;  </span>
  </li>
  <li class="alt">
  <span>if (strlen($str) </span><span class="tag"><</span><span> $str_tmp) {  </span></li><li><span>$</span><span class="attribute">tmpstr</span><span> = $str;  </span></li><li class="alt"><span>} else {  </span></li><li><span>$</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, $i, 1);  </span>
  </li>
  <li><span>}  </span></li>
  <li class="alt"><span>}  </span></li>
  <li>
  <span>$tmpstr </span><span class="attribute">.</span><span>= </span><span class="attribute-value">".."</span><span>;  </span>
  </li>
  <li class="alt"><span>}  </span></li>
  <li><span>return $tmpstr;  </span></li>
  <li class="alt"><span>}  </span></li>
  </ol>

  The above code is the specific implementation method for PHP to intercept Chinese characters without garbled characters. I hope it will be helpful to everyone.
