It can easily access all databases through PHP objects, such as MYSQL. REST has nothing to do with technology. It represents a software architecture style, REST It is the abbreviation of Representational State Transfer, and the Chinese translation is "Representational State Transfer" REST looks at the entire network from the perspective of resources. It identifies the resources distributed at a certain node in the network through URLs, and the client application Obtain representations of resources through URLs, and obtaining these representations causes these applications to change statesAll data, whether obtained through the network or data operated (add, delete, modify, check), are resources, treat all data as Resources are the most essential attribute that distinguishes REST from other architectural styles. For the resource-oriented architectural style of REST, someone has proposed a new structural concept, namely: Resource Oriented Architecture (ROA) ##

Testing, validating, and filtering user input or custom data are important parts of any web application. PHP's filter extension is designed to make data filtering easier and faster. Why use filters? Almost all web applications rely on external input. This data usually comes from users or other applications (such as web services). By using filters, you can ensure that your application gets the correct input type. You should always filter external data! Input filtering is one of the most important application security topics.

The reason for developing the TPL library seems funny: the reason is that spirit and xpressive are too slow. It's not that execution is slow, but that compilation is slow.

Exchange rate changes have a direct regulatory effect on a country's import and export trade. Under certain conditions, external devaluation of the domestic currency, that is, an increase in the exchange rate, will play the role of promoting exports and restricting imports; conversely, external appreciation of the domestic currency, that is, a decrease in the exchange rate, will play the role of restricting exports and increasing imports.

Munee has a very powerful caching function that can cache resources on the server and client servers. And it integrates the tool Imagine for image processing, which can quickly adjust the image size online, or crop the image, etc. Munee can automatically compile LESS, SCSS and CoffeeScript, and can also merge multiple CSS and JS files into a single request, as well as minify and GZip these files to save bandwidth and better website performance.

Monolog is a relatively complete and easily expandable logging library under PHP. Currently, many well-known PHP frameworks including Symfony, Laravel, CakePHP, etc. have built-in Monolog. Monolog can send your logs to files, sockets, inboxes, databases and various web services. Monolog follows the PSR3 interface specification and can be easily replaced with other logging libraries that follow the same specification. Monolog has good scalability. Through the interfaces Handler, Formatter and Processor, the Monolog class library can be extended and customized in various ways. Basic usage<?php  use Monolog\Logger;  use Monolog\Handler\StreamHandler;    // 创建日志频道  $log = new Logger('name');  $log->pushHandler(new StreamHandler('path/to/your.log', Logger::WARNING));    // 添加日志记录  $log->addWarning('Foo');  $log->addError('Bar');Core conceptEach Logger instance contains a channel name (channel) and a handler stack. When you add a record, the record is processed through the handler stack. Each handler can also decide whether to pass the record to the next handler in the next stack. Through handlers, we can implement some complex log operations. For example, if we put the StreamHandler at the bottom of the stack, all log records will eventually be written to the hard disk file. At the same time, we put the MailHandler at the top of the stack and send the error log via email by setting the log level. There is a $bubble attribute in Handler. This attribute defines whether the handler intercepts records and prevents them from flowing to the next handler. So if we set the $bubble parameter of MailHandler to false, when an error log occurs, the log will be sent through MailHandler instead of being written to the hard disk through StreamHandler. Multiple Loggers can be created, and each can define its own channel name and handler stack. Handlers can be shared among multiple Loggers. The channel name will be reflected in the log, making it easier for us to view and filter log records. If the log format (Formatter) is not specified, Handler will use the default Formatter. The log levels cannot be customized. Currently, the eight levels defined in RFC 5424 are used: debug, info, notice, warning, error, critical, alert, and emergency. If you have other needs for log records, you can add content to the log records through Processo. Log levelDEBUG (100): Detailed debug information. INFO (200): Key event. NOTICE (250): An ordinary but important event. WARNING (300): A non-error exception occurred. ERROR (400): Runtime error, but does not need to be handled immediately. CRITICA (500): Serious error. EMERGENCY (600): The system is unavailable.
