本文實例講述了PHP實現通過get方式識別用戶發送郵件的方法。分享給大家供大家參考。具體如下：

send_email.php如下：

<?php

$conn=mysql_connect("localhost","root","admin");

mysql_select_db("songyunb_development",$conn);

$id=$_GET["id"];

$sql="insert into email (sender_id,accepter_id,flag) values ('".$_SESSION["id"]."','".$id."','no')";

$query=mysql_query($sql);

if($query)

{

echo "<script>alert('?????????');</script>";

echo "<script>window.location.href='reg.php'</script>";

}

?>

reg.php如下：

<?php

$conn=mysql_connect("localhost","root","admin");

mysql_select_db("songyunb_development",$conn);

$sql="select * from comments";

$query=mysql_query($sql);

while($out=mysql_fetch_array($query))

{

echo $out["content"]."-------<a href='newfile.php?id=".$out["id"]."'>查看郵件</a><br/>";

}

?>

newfile.php如下：

<?php

$conn=mysql_connect("localhost","root","admin");

mysql_select_db("songyunb_development",$conn);

$result="";

$id="";

if(isset($_GET["id"]))

{

$id=$_GET["id"];

$sql="select * from comments where id='".$_GET["id"]."'";

$result=mysql_query($sql);

}

$out=mysql_fetch_array($result);

echo $out["content"]."<br/>";

echo $out["created_at"]."<br/>";

echo "<a href='send_email.php?id=".$out["id"]."'>發送郵件</a><br/><hr>";

//看看有沒有新郵件

$sql_search_email="select * from email where accepter_id='".$id."'";

$query=mysql_query($sql_search_email);

$result_email=mysql_fetch_array($query);

if($result_email["accepter_id"]==$_SESSION["id"]&&$result_email["flag"]=="no")

{

echo "<strong><a href='see_email.php?id=".$result_email["id"]."'>您有新郵件</a></strong>";

}

?>

login.php如下：

<?php

$conn=mysql_connect("localhost","root","admin");

mysql_select_db("songyunb_development",$conn);

$_SESSION["id"]=15;

echo "<a href='delete_session.php'>清除session</a>";

echo "<a href='reg.php'>重新注冊</a>";

?>

delete_session.php如下：

<?php

if(isset($_SESSION["id"]))

{

unset($_SESSION["id"]);

}

echo "<script>alert('清除成功');</script>";

?>

希望本文所述對大家的php程序設計有所幫助。
