这样写一个包含文件,为啥中文部分出现乱码
一共两个文件:
A,index.php文件的代码:
- PHP code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <?php require("/title.php"); ?> ...test.....
B,title.php文件的代码:
- PHP code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> <?php header(“Content-Type: text/html; charset=utf-8") ?> <title>中文标题(beta 1.0)----Powered by Aloesky</title> <meta name="keywords" content=""> <meta name="description" content=""> <link href="../css/css.css" rel="stylesheet" type="text/css"> <link href="../css/menu.css" rel="stylesheet" type="text/css">
在PHP环境中测试,上文中“中文标题”这几个字变成乱码了,无论怎么声明UTF-8都无效
求大神们赐教
------解决方案--------------------
都是UTF-8 文件的编码格式也必须一致即可.
------解决方案--------------------
因为文件不是utf8的, 空白是BOM, 去掉。
------解决方案--------------------
楼主去下个:Notepad++
非常棒的代码编辑器。
要去除存在UTF-8文件中的BOM,你只需要使用NotePad++打开这个文件,然后选择“格式”,再选择“以UTF-8无BOM格式编码”,最后重新保存文件即可!
使用Notepad++去除UTF-8文件中的BOM
本文的最后,我介绍一个小经验:
当大家在碰到网页解析上(包括CSS和HTML解析)的诸多奇怪问题(比如这个由BOM导致的奇怪空白行)时,切勿急躁,首先应该确定你的代码编写无误;如果问题仍然存在,将代码提交到W3C网站 进行HTML验证 和CSS验证 ;最后根据验证结果的提示,更正自己的代码。尽量遵守W3C规范,按这个流程,一般问题都能得到解决。 W3C组织官方网站:http://validator.w3.org/

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
