本文讲述如何使用PHP和Ajax创建一个过滤敏感词汇的方法,判断是否有敏感词汇。
敏感词汇数组sensitive.php
return array ( 0 => '111111', 1 => 'aaaaaa', 2 => 'bbbbbb', 3 => 'ccccc', 4 => 'dddd', 5 => 'eeee', ........ )
判断是否有敏感词汇
$("#add").click(function() { var content = $("#content").val(); $.ajax({ type: "POST", url: "ajax.php", data: "content=" + content, success: function(data) { if (data) { $("#message").html(data).show(); } else { $("#message").html('没有敏感词汇').show(); } } }); });
PHP判断数组里是否有敏感词汇,若是有则输出
$content = htmlspecialchars($_POST['content']); $arr= include 'sensitive.php'; foreach ($arr as $v) { if (false !== strstr($content, $v)){ echo "含有敏感词汇 ".$v; exit; } }
