php在电脑上运行正常在linux终端机上却不正常 求解 头疼当中
我的php文件内容:
一直提示 fatal error; call to a member function query() on a non-object online 16
$DB->connection->query("create table test(id integer primary key,name varchar(50),grade varchar(50),score varchar(50))");一直提示这行出错我贴在这里
我在电脑上运行是完全正常的 可以插入数据 是在linux终端机上运行时就一直提示错误 要疯了 是终端机设置的问题吗
header("content-Type: text/html; charset=Utf-8");
//获取uiceshi.html页面提交过来的数据
$fname = $_POST['fname']; //姓名
$fgrade = $_POST['fgrade']; //年级
$fscore = $_POST['fscore']; //分数
//$sql = 'insert into test values ();';
//创建一个数据库实例
$DB = new SQLite('blog.db'); //这个数据库文件名字任意
//创建表名为test的表
$DB->connection->query("create table test(id integer primary key,name varchar(50),grade varchar(50),score varchar(50))"); 提示这行出错
//执行插入语句
//$result = $DB->query("insert into test(name,grade,score) values('".$fname."','".$fgrade."','".$fscore."')");
$result = $DB->connection->query("insert into test(name,grade,score) values('".$fname."','".$fgrade."','".$fscore."')");
//返回结果 主要是用来调试的
print_r($result);
//SQLite类
class SQLite
{
function __construct($file)
{
try
{
$this->connection=new PDO('sqlite:'.$file);
}

function query($sql) //直接运行SQL,可用于更新、删除数据
{

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

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.
