PHP脚本安装系统创建

在根文件夹（htdocs）中创建两个新文件夹（包括并安装）。在include文件夹中创建新文件 connect.php 和 DB_Info.php 在代码编辑器中打开 connect.php ，并在 connect.php 中编写@mysql_connection代码始终使用 connect.php 文件包含/要求连接数据库文件|

<?php  // Always Include/Require This File For Connect Database
    require_once "DB_Info.php";  // this is connect.php file

    @mysqli_connect(
        $HOST_name,
        $DB_username,
        $DB_password
    ) or die(
        "<h2>Database Error, Contact With Admin </h2>"
    );

    @mysqli_select_db(
        $DB_name
    ) or die(
        "<h2>Database Error, Contact With Admin</h2>"
    );
?>

require_once DB_Info.php 保持空白|你可以在connect.php中看到 $ HOST_name，$ DB_username，$ DB_password var没有值我们在DB_Info.php（require file）|中提供表单中的值现在将 index.php ， Installing.php ， installed.php 三个文件创建到安装文件夹 1st index.php创建表单 - ＆gt;

<link rel='stylesheet' href='style.css' />

<?php  // create form
    $HOST_name = "<input class='input' type='text' name='dbhost' placeholder='Enter Host Name' />";
    $DB_username = "<input class='input' type='text' name='dbuser' placeholder='Enter DB User Name' />";
    $DB_password = "<input class='input' type='password' name='dbpass' placeholder='***********' />";
    $DB_name = "<input class='input' type='text' name='dbname' placeholder='Enter DB Name' />";
    echo "<div class='box' >
            <form class='ins' method='post' action='installing.php' >
                    <p>Enter Host Name:<p>
                    $HOST_name
                    <p>Enter DB User Name:<p>
                    $DB_username
                    <p>Enter DB PassWord:<p>
                    $DB_password
                    <p>Enter DB Name:<p>
                    $DB_name
                    <input class='submit' type='submit'name='install' value='NEXT' />
            </form>
        </div>";
?>

表单操作 Installing.php 现在我们使用文件处理函数 fwrite（）将三个var值写入 DB_Info.php （连接.php $ HOST_name，$ DB_username，$ DB_password ） installing.php-＆GT;

<link rel='stylesheet' href='style.css' />
<?php  
    $writer="<?php".'
    '.'$HOST_name = '."'".$_POST['dbhost']."'".';
    '.'$DB_name = '."'".$_POST['dbname']."'".';
    '.'$DB_username = '."'".$_POST['dbuser']."'".';
    '.'$DB_password = '."'".$_POST['dbpass']."'".';
    '."?>";

    $write=fopen('..\include/DB_Info.php' , 'w');
    if(empty($_POST['dbhost']&&
             $_POST['dbname']&&
             $_POST['dbuser']&&
             $_POST['dbpass'])){
                 echo"<h2 align=center >All Fields are required! Please Re-enter</h2>";

    }else{
        if(isset($_POST['install']))
        {
            fwrite($write,$writer);
            fclose($write);
            echo "<div class='box'>
                <form class='ins' action='installed.php' method='post'>
                    <h2 align=center color=red>Database Info Succecfully Entered<h2>
                    <input class='submit' type='submit' value='NEXT' name='next'/>
                </form>
                </div>";
        }else{ echo "<h2 align=center >Error<h2>"; }}
?>

最后一步 installed.php ，用于将表创建到phpmyadmin - ＆gt;

<?php
    if(isset($_POST['next'])){
        /*  enter your
         sql code for
         teble creating */
        echo"<h2 align=center >Finished</h2>";
    }else{
        echo"<h2 align=center >Error</h2>";
    }
?>

我们的CSS

* {
    margin: 0;
    padding: 0;
}

.box {
    position: absolute;
    width: 300px;
    top: 16%;
    left: 35%;
    background-color: rgb(0, 0, 0);
    padding: 15px;
    padding-top: auto;
}

.ins {
    margin: 0;
    padding: 0;
    font-weight: bold;
    color: lawngreen;
    font-size: 1rem;
}

.input {
    border: none;
    border-bottom: 2px solid lawngreen;
    margin-bottom: 20px;
    width: 100%;
    height: 40px;
    background: transparent;
    outline: none;
    color: cyan;
    font-size: 1rem;
}

.submit {
    background-color: lawngreen;
    width: 100%;
    height: 40px;
    font-size: 1.5rem;
    border: none;
    margin-top: 10px;
    outline: none;
    cursor: pointer;
    border-radius: 20px;
}
