Question

首先。我是PHP的新手。所以请理解。我已经尝试使用session将createmessage.php的结果回显到index.php

Createmessage.php

        $sql = "INSERT INTO tbl_convo(t_datetime,t_subject, t_message, t_category, t_ipaddress, t_password) VALUES('$date','$subject','$message','$category','$ipaddress','$password')";
        $result=mysql_query($sql);

        $msg = "<div class='col-sm-12'><div class='alert alert-success' role='alert' style='text-align:center;'>Successfull Sent</div></div>";
        $_SESSION['answer'] = $msg; 

        header('Location: index.php');

的index.php

<?php if( !isset($_SESSION['answer'])) {$array = $_SESSION['answer']; echo $array; } ?>

请帮助我解决这个问题。

Answer 1

你反过来做。而不是

for(a=i;a<=j;a++)
    if(p[a]>=x) // p[] is array containing n elements
    count++;

你需要做

if (!isset ...

<?php
    session_start();
    $_SESSION['color'] = 'green';
?>

查看PHP SESSIONS
