JSP能否被PHP取代？

<%@ page import="java.sql.*" %>
<%
Connection conn = null;
try {
    Class.forName("com.mysql.jdbc.Driver");
    conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "password");
    Statement stmt = conn.createStatement();
    ResultSet rs = stmt.executeQuery("SELECT * FROM users");
    while (rs.next()) {
        out.println(rs.getString(1) + " " + rs.getString(2));
    }
    conn.close();
} catch (Exception e) {
    e.printStackTrace();
}
%>

<?php
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "test";

$conn = new mysqli($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()) {
        echo $row["id"] . " " . $row["name"];
    }
} else {
    echo "0 results";
}

$conn->close();
?>

<%
out.println("Hello, JSP!");
%>

<?php
echo "Hello, PHP!";
?>
