Question

我需要一些帮助来添加搜索栏以搜索我的.txt文件。我想要的是用户可以搜索和比较他们的搜索与我的moviedata.txt文件中的内容的方式。我真的只希望他们按电影标题名称搜索，而不是数据或流派。我希望它以PHP形式，并且只是基于他们搜索提供的结果以数组形式。所以最有可能需要一个数组。它可能需要在txt文件中每行末尾的分隔符才能使搜索栏成为可能。我将在下面发布我的html和moviedata.txt信息。

感谢您的帮助。

Answer 1

您应该考虑将数据迁移到数据库。

使用这样的SQL语句在数据库中搜索会很容易：

"SELECT * FROM `movies` WHERE title LIKE '%" . $searchQuery . "%'";

编辑：要在文本文件中进行实际搜索，您可以使用他们在此帖中提出的解决方案：PHP to search within txt file and echo the whole line

编辑2：您可以按照本教程制作表格：http://php.about.com/od/learnmysql/ss/create_tables_2.htm

你可以像这样设计你的表：

 ID  |  Title  | Genre | ETC...
 ____|_________|_______|_______
  1  | Starwars|Scifi  | etc...

然后在php中你需要连接到mysql。

你可以这样做：

<?php

// CONNECT TO THE DATABASE

$DB_NAME = 'DATABASE_NAME';

$DB_HOST = 'DATABASE_HOST';

$DB_USER = 'DATABASE_USER';

$DB_PASS = 'DATABASE_PASSWORD';



$mysqli = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);



if (mysqli_connect_errno()) {

    printf("Connect failed: %s\n", mysqli_connect_error());

    exit();

}




// A QUICK QUERY ON A FAKE USER TABLE

$query = "SELECT * FROM `tablename` WHERE `Title` LIKE '%" . $search . "%'";

$result = $mysqli->query($query) or die($mysqli->error.__LINE__);




// GOING THROUGH THE DATA

if($result->num_rows > 0) {

    while($row = $result->fetch_assoc()) {

        echo $row['Genre']);    

    }

}

else {

    echo 'NO RESULTS';  

}



// CLOSE CONNECTION

mysqli_close($mysqli);
