echo ,print_常用的输出方式有：echo、print、print_r、var_dump、var_exprot等；echo和print常用来输出字符串；查看数组常用print_r、var_dump、var_exprot；r()<?php include("conn/conn.php"); if(trim($_POST[username])!= "" and trim($_POST[password])!= "" and trim($_POST[tel])!=""){ $pwd = md5($_POST[password]); $sql = "insert into tb_user(username,password,address,explains)values('".$_POST[username]."','".$pwd."','".$_POST[address]."','".$_POST[tel]."')"; $result = mysql_query($sql,$conn); if($result){ echo "<font color='red'>注册成功。</font>"; }else{ echo "<font color='green'>注册失败!</font>"; } }else{ echo "请认真填写用户名和密码！"; }?>
