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; 
    } 
}
