ajax 做注册页面检测用户名是否存在页面
我想把传过来的值打出来
file_put_contents("E:/user.log",$name."\r\n",FILE_APPEND);
<?php
header("Content-type:text/html; charset=utf-8");
$name = $_GET['regname'];
//file_put_contents("E:/user.log",$name."\r\n",FILE_APPEND);
//require_once("conn.php");
mysql_connect("localhost","root","") or die("Can't connect database: ".mysql_error());
mysql_select_db("message");
mysql_query("SET NAMES 'utf8'");
$select = "select * from user where username='$name'"; //后台验证用户名是否存在
$nums = mysql_num_rows(mysql_query($select));
if($nums!=0){
echo "1";
}
else{
echo "0";
}
?>
