php判断正常访问和外部访问
复制代码 代码如下:
<?php
session_start();
if(isset($_POST["check"])&&!empty($_POST["name"])){
if($_POST["check"] == $_SESSION["check"]){
echo "正常访问";
}else{
echo "外部访问";
}
}
$token = md5(uniqid(rand(),true));
$_SESSION["check"] = $token;
?>
<form method="post" action="">
<input type="text" name="name"/>
<input type="text" name="check" value="<?=$token;?>">
<input type="submit">
