With a few "preview" exceptions, the extension functions you have dealt with so far have been simple, returning only. However, most functions do not have just one Purpose. You will usually pass some parameters and hope to receive a useful response based on the value and other additional processing. The automatic type conversion of zend_parse_parameters() is the same as the return value you saw in the previous chapter. The value of the parameter is also around the zval references are expanded. The easiest way to obtain the values of these zval* is to use the zend_parse_parameters() function. Calling zend_parse_parameters() is almost always followed by the ZEND_NUM_ARGS() macro followed by the ubiquitous TSRMLS_CC. ZEND_NUM_ARGS() can be used from the name As you can guess, it returns the actual number of parameters passed as an int. Due to the way zend_parse_parameters() works internally, you may not need to know this value directly, because

About the solution to the failure of page script assignment due to a carriage return in the string when passing parameters in the url address_PHP Tutorial
Introduction: Regarding the solution to the problem that the page script assignment fails due to a carriage return in the string when passing parameters in the url address. When accepting parameters through the url address, the value V of some parameters has a carriage return '%0A'. At this time, when the page script is displayed, paying this value V to the script variable may cause errors in the script5.

Single-row function Single-row function: operates data objects, accepts parameters and returns a result, only transforms one row, returns a result for each row, can convert data types, can be nested, the parameter can be a column or a DUAL is a' Pseudo table' can be used to test functions and expressions 2.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
