MYSQL 特殊字符怎么处理？
这个语句
mysql_query("update users set active_date = '2012-3-13' where computer_key = '18:A9:05:A1:3D:83 90:4C:E5:A1:36:2A'");

就因为后面有冒号或者空格的存在，导致无法更新。
我该怎么处理一下啊?谢谢了。

PHP code

$s=preg_replace('/[: ]/','',$s);<br><font color="#e78608">------解决方案--------------------</font><br>按这个条件select一下  看有没有结果出来<br><font color="#e78608">------解决方案--------------------</font><br>转义一下<br><font color="#e78608">------解决方案--------------------</font><br>如果是特殊字符，用htmlentities可以转义。说明下，空格绝对不是特殊字符。<div class="clear">
                 
              
              
        
            </div>
