Writing PHP programs these days, I feel that many places are not as smooth as asp, asp.Net, and jsp. For example, it is not convenient to use session_first-come-first-served session_start();, and the file jump header is not convenient....
Maybe It’s some features of PHP that I’m not familiar with, but if I write too much, I’ll get used to it gradually.....
Here is a code writing and debugging problem. The error is as follows:
Parse error: syntax error, unexpected $end in D:xampphtdocsguestBookguestBook.php on line 330
Look at line 330 of the program, the last line of code, what is wrong with this? Searched on google and found:
In PHP 5, the following error may appear as an error entry in Apache error log or simply displays on PHP web page, even if calling to php scripts with php_info() works perfectly and successfully returns information on PHP configurations:
Parse Error: syntax error, unexpected $end in ….. scripts.php on line …
The error may caused by a missing curly bracket in PHP script coding. Besides, it may also caused by error in PHP coding in class definition, as in PHP, a class definition cannot be broke up and distributed into multiple files, or into multiple PHP blocks, unless the break is within a method declaration.
But more commonly, the error is often caused by the use of Short Open tags in PHP,
To use short open tags, it must be enabled in PHP.INI. Search for short_open_tag in PHP .INI, and change the value to On. The line should look line:
short_open_tag = On
Is your English bad? After looking at several other searches, none of them got to the point, so let’s look at English. Although it can’t be fully translated, the general meaning is clear:
The error occurred due to the use of short tags, which can be found in Set short_open_tag = On in php.ini
It turns out that the Parse error prompt is usually a syntax error, using an open tag, and the statement is not ended, which is some basic programming mistakes, such as not paying attention to adding ";" at the end of the statement or Forgot "}" after if(){...}; Forgot "?>". Checking the code carefully, it turns out that "}" is missing somewhere, and the modified program runs normally.

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.
