Functional comparison between JSP and PHP
Function comparison between JSP and PHP
In the field of web development, JSP (JavaServer Pages) and PHP (Hypertext Preprocessor) are two A common back-end programming language. They both have the ability to handle dynamic web content, but there are some clear differences in syntax, functionality, and usage. This article will compare the functions between JSP and PHP through specific code examples.
Grammar style
JSP
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8 "%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>
<head>
<title>Hello World!</title>
</head>
<body>
<h1 id="Hello-request-getParameter-name">Hello, <%= request.getParameter("name") %>!</h1>
</body>
</html>PHP
<!DOCTYPE html>
<html>
<head>
<title>Hello World!</title>
</head>
<body>
<h1 id="Hello-php-echo-GET-name">Hello, <?php echo $_GET["name"]; ?>!</h1>
</body>
</html>Database operation
JSP
<%@ page import="java.sql.*" %>
<%
String url = "jdbc:mysql://localhost:3306/mydatabase";
String user = "root";
String password = "password";
try {
Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection(url, user, password);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM users");
while (rs.next()) {
// Process data here
}
conn.close();
} catch (Exception e) {
out.println("Error: " e.getMessage());
}
%>PHP
<?php
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "mydatabase";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM users";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
// Process data here
}
}
$conn->close();
?>Integrate other technologies
JSP
JSP is very suitable for integration with Java technology, Java EE containers and other Java frameworks, such as Servlet, JSTL, Spring, etc.
PHP
PHP can interact with various databases, such as MySQL, PostgreSQL, SQLite, etc., and can also easily integrate front-end technologies such as JavaScript, HTML, and CSS.
Performance and scalability
JSP
JSP usually runs with Java application servers, such as Tomcat, Jetty, etc., and has good performance and scalability. But compiling JSP files may increase deployment time.
PHP
As a scripting language, PHP is used with web servers such as Apache and has good performance and high scalability. But for large applications, more optimization and tuning may be required.
Conclusion
JSP and PHP are both powerful back-end programming languages with their own advantages and characteristics. The choice of which language to use depends on project needs, development team skills, and the actual scenario. Through the above comparison, I hope readers can have a clearer understanding of the functional differences between JSP and PHP, and provide a reference for web development decisions.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
