The function to filter sensitive words does not work.

<code>function guolv($data){
        $mgc=array("哈哈","哦");
        for ($i=0; $i &lt;count($mgc) ; $i++) { 
          $data=str_replace($mgc[i], “*”, $data);
        }
          return $data;
      }</code>

I wrote a function to filter sensitive words, but it doesn’t work. Please give me some advice.

<code>$mgc[i] &gt;&gt;&gt; $mgc[$i]</code>

This situation may be simpler to write like this

$mgc=array("哈哈","哦");
str_replace($mgc, '*', $mgc);

<code>function guolv($data){
        $mgc=array("哈哈","哦");
        for ($i=0; $i &lt;count($mgc) ; $i++) { 
          $data=str_replace($mgc[$i], “*”, $data);//原为$msg[i]
        }
          return $data;
      }
