1、首先创建敏感字的数据表，来存放敏感字
3、把敏感词替换成*的函数public function 嘛术铹砾words($bw){ $word = M("words")->稆糨孝汶;select();//敏感词库 $string = ""; foreach( $word as $k=>$v ){ $badword[] = $v['words']; $len = mb_strlen($v['words'], 'UTF-8'); $str = ""; for ($x=0; $x<$len; $x++) { $str .= "*"; } $string .= $str; $string .=","; } $laststr = rtrim($string,",");// $words = explode(",",$laststr);//把字符串转为数组 $badwords = array_combine($badword,$words);//合并两个数组 return $str = strtr($bw, $badwords);//把敏感词替换成* }
5、执行结果如图所示（如果您不想替换成*，也可以替换成别的符号。）
