How to use PHP to develop simple recruitment information publishing and filtering functions
With the popularity of the Internet and people's demand for employment opportunities, recruitment websites are becoming more and more important. In this article, I will introduce you to how to use PHP to develop a simple website with job posting and filtering functions. We will start from creating the database, to designing the user interface, and finally writing PHP code to implement the functionality.
- Database Design
In this application, we need to store data related to recruitment information. So we need to create a database to store this data. The following is a simple database design:
CREATE DATABASE recruitment; USE recruitment; CREATE TABLE jobs ( id INT PRIMARY KEY AUTO_INCREMENT, title VARCHAR(255) NOT NULL, description TEXT NOT NULL, company VARCHAR(255) NOT NULL, location VARCHAR(255) NOT NULL, posted_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP );
In this database, we created a database named "recruitment" and created a "jobs" table in it to store job information. The table contains the job title, description, company name, location, and date posted.
- User Interface Design
Next, we need to design the user interface so that users can post new recruitment information and filter positions based on some conditions. The following is a simple user interface design:
<!DOCTYPE html> <html> <head> <title>招聘信息发布和筛选</title> </head> <body> <h1 id="招聘信息发布和筛选">招聘信息发布和筛选</h1> <h2 id="发布新的招聘信息">发布新的招聘信息</h2> <form action="post_job.php" method="post"> <label for="title">职位标题:</label> <input type="text" id="title" name="title" required><br><br> <label for="description">职位描述:</label><br> <textarea id="description" name="description" rows="5" cols="50" required></textarea><br><br> <label for="company">公司名称:</label> <input type="text" id="company" name="company" required><br><br> <label for="location">地点:</label> <input type="text" id="location" name="location" required><br><br> <input type="submit" value="发布招聘信息"> </form> <h2 id="筛选职位信息">筛选职位信息</h2> <form action="filter_jobs.php" method="post"> <label for="keyword">关键字:</label> <input type="text" id="keyword" name="keyword"><br><br> <label for="location">地点:</label> <input type="text" id="location" name="location"><br><br> <input type="submit" value="筛选职位"> </form> </body> </html>
This user interface contains two forms, one for posting new recruitment information and the other for filtering job information. Users can enter job titles, descriptions, company names and locations to post new job postings, or enter keywords and locations to filter job postings.
- PHP code implementation
Now let us write PHP code to implement these functions. Here is a simple code example:
post_job.php:
<?php $title = $_POST['title']; $description = $_POST['description']; $company = $_POST['company']; $location = $_POST['location']; // 连接到数据库 $conn = new mysqli('localhost', 'root', 'password', 'recruitment'); // 检查数据库连接是否成功 if ($conn->connect_error) { die("数据库连接失败: " . $conn->connect_error); } // 插入新的招聘信息 $sql = "INSERT INTO jobs (title, description, company, location) VALUES ('$title', '$description', '$company', '$location')"; if ($conn->query($sql) === TRUE) { echo "招聘信息发布成功!"; } else { echo "发布失败: " . $conn->error; } // 关闭数据库连接 $conn->close(); ?>
filter_jobs.php:
<?php $keyword = $_POST['keyword']; $location = $_POST['location']; // 连接到数据库 $conn = new mysqli('localhost', 'root', 'password', 'recruitment'); // 检查数据库连接是否成功 if ($conn->connect_error) { die("数据库连接失败: " . $conn->connect_error); } // 根据关键字和地点筛选职位信息 $sql = "SELECT * FROM jobs WHERE title LIKE '%$keyword%' AND location LIKE '%$location%'"; $result = $conn->query($sql); if ($result->num_rows > 0) { // 输出查询结果 while($row = $result->fetch_assoc()) { echo "职位标题: " . $row["title"]. "<br>职位描述: " . $row["description"]. "<br>公司名称: " . $row["company"]. "<br>地点: " . $row["location"]. "<br><br>"; } } else { echo "没有找到符合条件的职位信息。"; } // 关闭数据库连接 $conn->close(); ?>
In these codes, we first get the input from the user Get the data from the form and insert it into the database to post new job information. Then, the database is queried based on the keywords and locations entered by the user, and the query results are output to the user interface.
In summary, we have learned how to use PHP to develop a simple website with recruitment information publishing and filtering functions. By designing the database, user interface and writing PHP code, we are able to implement information publishing and filtering functions. Of course, this is just a starting point, you can extend and optimize this application according to your needs. Hope this article can be helpful to you!

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
