With the continuous development of information technology, search engines have become one of the important ways for us to obtain information. Adding a search box function to the website can facilitate users to quickly locate the information they need and improve user experience. This article will use PHP as an example to introduce how to implement the search box function in the website.

1. Understand the search box function

To implement the search box function, you first need to understand the basic principles of the search box. The search box usually consists of two main parts:

  1. Input box: used to enter the keywords to be searched.
  2. Search button: Clicking this button will trigger the search keyword query operation.

Through the search box, users can enter the keywords they want to query, and the background program will query relevant information from the database based on the keywords and display the search results on the page.

2. Create a database

Before implementing the search box function, you need to prepare the data first. We can store and query related data by creating a database. Next, let's create a simple database containing keywords and related links.

  1. Create a database: Open PHPMyAdmin, select "New Database", enter the database name, and select "Create".
  2. Create a data table: In the created database, select "New Data Table" and set the three fields of ID, keyword and link, where the ID is an automatically incrementing integer type.
  3. Insert data: Select "Insert" and enter relevant information in the input box.
  4. Display data: Select "Query" in the database to see the added data.

3. Create a search box

Next we need to create a search box on the website. In PHP, we can create a search box through HTML. The following is a simple search box code:


In the above code, we create a text input box named "query" and a submit button through an HTML form. The input box is used to enter keywords. After clicking the submit button, the system will call the background program to query the keywords.

4. Create a background query program

In the previous steps, we have created the database and search box. Next we need to write PHP code to compare the keywords in the input box with the database. Matches the data in the page and returns the results to the page. The following is the basic code of the search box background query program:

<?php //链接数据库
$conn = mysqli_connect("localhost","root","password","mydatabase");

//获取查询关键字
$query = $_GET["query"];

//查询操作,查找包含关键字的数据
$sql = "SELECT * FROM mytable WHERE keywords LIKE &#39;%$query%&#39;";

//执行查询操作
$result = mysqli_query($conn, $sql);

//输出查询结果
while($row = mysqli_fetch_array($result)) {
echo "<a href=&#39;" .$row[&#39;link&#39;]. "&#39;>" .$row['keywords']. "<br>";
}

//关闭数据库链接
mysqli_close($conn);
?>

In the above code, first we need to link to the database we created; then get the entered keywords from the query box; then perform the database query operation , find data containing keywords, and output the results to the page. Finally, close the database link and complete the entire query process.

5. Test the search box function

After completing all the above steps, let’s test the search box function. Enter the address of the search box into your browser and see if the search box works properly. Enter the query keyword and click the search button. If the query results can be displayed normally, it means that the search box function has been successfully implemented.

6. Summary

Using PHP to implement the search box function can greatly improve the usability and user experience of the website. Through the above introduction, we can understand the principle and implementation method of the search box. After mastering the relevant PHP knowledge, we can flexibly apply the search box function in the website to provide users with better services.
