【问题描述】：

我有一个可以工作的内容过滤器，但它并没有像我想要的那样工作。例如，如果我说“badword you i badword hat you”，则整个内容输出为“[CONTENT DELETED]”，但我希望它说“******* you i ******* hat you” "

<?php

function SecurePost($var) {
  return trim($DBcon->real_escape_string($var));
}

function filter($string) {
  $words = array("badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere", "badwordhere");
  $new =   array("****", "*****", "***", "*******", "****", "****", "*****", "******", "*****", "******", "*****", "***", "*******", "***", "****", "***", "*****", "*******", "****", "****", "*****", "****", "****", "****", "******");
  $string1 = str_ireplace($words, $new, $string);
  $findme = "***";
  $pos = strpos($string1, $findme);
  if ($pos !== false) {
    $string1 = "[ Content Deleted ]";
    return $string1;
  }
  else {
    return $string1;
  }
}

function SecureString($value) {
  $value = mysql_real_escape_string(stripslashes(strip_tags($value)));
  return $value;
}
?>

【问题讨论】：

这是一项不可能完成的任务，你可以捕捉到不好的词（使用很长的字典），但你无法捕捉到这些词的所有变体：FuUuCk, @ 987654323@... 简而言之，尝试这样做只是浪费时间，并不能取代版主。新闻：我们现在是2017年，您可以毫无风险地使用所有mysql_功能。
我知道我不能阻止他们，那不是我的问题......
也许，但这是我的答案。

【解决方案1】：

代码中的错误很少。请检查以下工作示例：

<?php
$str = "Kiss my badwordhere";
echo filter($str) . "\n";

$str = "badwordhere anywherebadword";
echo filter($str) . "\n";


function filter($string) {
  $words = array("badwordhere", "anywherebadword");
  $new =   array("****", "*******");
  $string1 = str_ireplace($words, $new, $string);
  $left = preg_replace("/[\* ]+/", "", $string1);
  if (strlen($left) == 0) {
    $string1 = "[ Content Deleted ]";
    return $string1;
  }
  else {
    return $string1;
  }
}
?>

打印

Kiss my ****
[ Content Deleted ]
