PHP core technologies and practices-PHP and database basics PDO (php data object) and PHP support almost all databases on the market, but the abstract access interfaces are not uniform. Therefore, PDO has emerged and provides a common interface to access multiple databases, that is to say, the abstract database model supports connecting to multiple databases. PDO extension is only an abstraction layer th

PHP core technology and best practices PHP uses PHPRPC protocol to call JAVA class SOAP (Simple Object Access Protocol, Simple Object Access Protocol) with the continuous competition and design of manufacturers, and because the transfer of objects cannot achieve interoperability, SOAP gradually changes to the transfer of strings, and is finally designed as the XML-based WebService. PHPRPC protocol: it

ZendAPI and programming of PHP core technologies and best practices The Zend Engine provides many API extensions for PHP. with these APIs, you can easily compile and write Extensions. Next, we will first learn about the Zend Engine. The Zend Engine is a scripting language engine (parser + Virtual Machine). The main task is to parse, translate, and execute PHP scripts. The process is as follows: The Zen

PHP core technology and best practices-implementation mode of Web services PHP supports two WEB service models: WSDL and non-WSDL, first, we will introduce two implementation modes of Web services: Contract First) Code First) Contract first mode: defines the WSDL (WEB Services Description Language) file for the Web service interface. The WSDL file describes the WEB service location, available operation

Introduction to ASP. NET Core middleware and project practices, asp. netcore Preface This article is actually used in the development of our own projects. It fits into the actual application and is an in-depth use of middleware, not a simple Hello World. Role of Middleware (Middleware) We know that any web framework encapsulates http requests into a pipeline, and each request passes through a series of oper

Rare to buy and like a good book, ' PHP core technology and best practices '.A few days, first looked at a general, summed up what the whole is like, how to see how to learn. 1, a total of 14 chapters;2, 1th, 2, the Oop of PHP;The first chapter focuses on PHP's OOP and Java, and so on, in the face of conceptual issues of object development, the special aspects of PHP oop, and give a code example;3, 3rd, 4

PHP core technology and best practices errors and output APIs cannot be simply printed using the printf () function in the PHP kernel, because PHP has its own set of functions for managing output streams, if you call the printf () function to print data, unexpected results may occur. The following describes the PHP output API. 1) php_printf () function: php_printf () is similar to the printf () function o

PHP core technology and best practices assign values to variables in PHP extensions read this section. if you do not know the structure of variables in PHP, go to: variables in the PHP kernel. The function of a variable is to store data. because a variable in PHP not only saves the value but also the type, it must not only assign values to the variable, but also set the type for the variable. 1) long i

regular expression matching rules for PHP core technology and best practices This article describes several common matching rules. 1. Character groups Finding numbers, letters, and blanks is simple because you already have metacharacters that correspond to these collections, but if you match a character set that doesn't have predefined metacharacters, it's simple to list them in square brackets. For ex

I. Thread creation:Operation objectis may create threads faster. For details, refer to: iOS core system programming best practices: concurrency.1. Thread creation requires a large amount of memory and time consumption. Therefore, we recommend that you use the entry point function to do a considerable amount of work, or create a Run Loops to allow regular work.2. Run Loops allows you to create long-running t

. MicroServices first emphasize the small scale of services and ease of scaling and expansion of services, but this can also lead to fragmentation of services and challenges to personnel management.2. MicroServices are a distributed system, each of which has its own database, although to a certain extent increases the overall reliability of the application, but also inevitably brings a lot of redundant data.3. As the scale of services grows, the number of instances of microservices will grow rap
