Configure the server. When accessing php, it prompts PHP Parse Error: syntax error, unexpected $end error. Share my solution. When writing PHP programs these days, I feel that many aspects are not as smooth as ASP, ASP.NET, and JSP. For example, using session_first-come-first-server session_start(); and using file jump headers are not convenient.... Maybe it’s some features of PHP that I’m not familiar with, but as I write more, I’ll gradually get used to it... Complete 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’s 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 roughly meaning: The error occurs because short tags are used. You can set short_open_tag = On in php.ini It turns out that Parse error prompts are usually grammatical errors, using open tags, and not ending the statement, which are some basic programming mistakes, such as not paying attention to adding ";" at the end of the statement or forgetting "} after if(){...} ";forgot"?>". Checking the code carefully, it turns out that "}" is missing somewhere, and the modified program runs normally. |

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.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
