使用方法:

1、将如下代码保存为 360_safe3.php 文件并上传到要包含的文件的目录

2、在页面中引入上述 360_safe3.php 文件:require_once('360_safe3.php');

如果想整站防注,就在网站的一个公用文件中,如数据库链接文件 config.inc.php 中引入!

<?php
// yangjunwei.com
function customError($errno, $errstr, $errfile, $errline)
{
 echo "<b>Error number:</b> [$errno],error on line $errline in $errfile<br />";
 die();
}
set_error_handler("customError",E_ERROR);
$getfilter="&#39;|(and|or)\\b.+?(>|<|=|in|like)|\\/\\*.+?\\*\\/|<\\s*script\\b|\\bEXEC\\b|UNION.+?SELECT|UPDATE.+?SET|INSERT\\s+INTO.+?VALUES|(SELECT|DELETE).+?FROM|(CREATE|ALTER|DROP|TRUNCATE)\\s+(TABLE|DATABASE)";
$postfilter="\\b(and|or)\\b.{1,6}?(=|>|<|\\bin\\b|\\blike\\b)|\\/\\*.+?\\*\\/|<\\s*script\\b|\\bEXEC\\b|UNION.+?SELECT|UPDATE.+?SET|INSERT\\s+INTO.+?VALUES|(SELECT|DELETE).+?FROM|(CREATE|ALTER|DROP|TRUNCATE)\\s+(TABLE|DATABASE)";
$cookiefilter="\\b(and|or)\\b.{1,6}?(=|>|<|\\bin\\b|\\blike\\b)|\\/\\*.+?\\*\\/|<\\s*script\\b|\\bEXEC\\b|UNION.+?SELECT|UPDATE.+?SET|INSERT\\s+INTO.+?VALUES|(SELECT|DELETE).+?FROM|(CREATE|ALTER|DROP|TRUNCATE)\\s+(TABLE|DATABASE)";
function StopAttack($StrFiltKey,$StrFiltValue,$ArrFiltReq){ 
 
if(is_array($StrFiltValue))
{
    $StrFiltValue=implode($StrFiltValue);
} 
if (preg_match("/".$ArrFiltReq."/is",$StrFiltValue)==1){  
        //slog("<br><br>操作IP: ".$_SERVER["REMOTE_ADDR"]."<br>操作时间: ".strftime("%Y-%m-%d %H:%M:%S")."<br>操作页面:".$_SERVER["PHP_SELF"]."<br>提交方式: ".$_SERVER["REQUEST_METHOD"]."<br>提交参数: ".$StrFiltKey."<br>提交数据: ".$StrFiltValue);
        print "360websec notice:Illegal operation!";
        exit();
}     
} 
//$ArrPGC=array_merge($_GET,$_POST,$_COOKIE);
foreach($_GET as $key=>$value){
    StopAttack($key,$value,$getfilter);
}
foreach($_POST as $key=>$value){
    StopAttack($key,$value,$postfilter);
}
foreach($_COOKIE as $key=>$value){
    StopAttack($key,$value,$cookiefilter);
}
if (file_exists(&#39;update360.php&#39;)) {
    echo "请重命名文件update360.php,防止黑客利用<br/>";
    die();
}
function slog($logs)
{
  $toppath=$_SERVER["DOCUMENT_ROOT"]."/log.htm";
  $Ts=fopen($toppath,"a+");
  fputs($Ts,$logs."\r\n");
  fclose($Ts);
}
?>
Copy after login
