A data structure refers to a collection of data elements that have one or more specific relationships with each other. Often, carefully selected data structures can lead to higher operating or storage efficiency. Data structures are often related to efficient retrieval algorithms and indexing techniques.

Advantages: relatively easy to implementDisadvantages: increased delay, at least two requests must be sent, the first request to obtain the resource list, and the second request to obtain the selected copy. (2) Server driverThe server checks the client's request header set and decides which version of the page to provide. Advantages: Faster than client-driven negotiation. HTTP provides a q mechanism that allows the server to approximate matching, and also provides a vary header for the server to tell downstream devices (such as proxy servers) how to evaluate the request. Disadvantages: The header set does not match, the server has to make guesses(3) Transparent negotiationAn intermediate device (usually a cache proxy) negotiates on behalf of the clientAdvantages: Eliminates the negotiation overhead of the web server and is faster than client-driven negotiation. Disadvantages: HTTP does not provide corresponding specifications

PHP needs to support more database connection interfaces. If you only write programs for a single database through a single interface, this will greatly increase the complexity and learning threshold of PHP. The abstract PHP library for payment emerged to solve this problem. This defines a lightweight, consistent interface for PHP to access the database. It provides a data access abstraction layer. No matter what database PHP is connected to, it can perform queries and obtain data through consistent functions. PDO began to ship with the release of php5.1. Previous versions of php did not support the abstract PHP library for payment Features: (1) Flexibility, which can be used during php running, Load new databases directly without resetting and compiling when new databases are used. (2) Object-oriented: Control the use of the database through objects. (3) Fast. Since PDO is written in C language and compiled into PHP, it is much faster than those abstract classes written in PHP.

Laravel is a simple and elegant PHP Web development framework (PHP Web Framework). It can free you from messy codes like noodles; it can help you build a perfect network APP, and every line of code can be concise and expressive. Laravel already has an advanced PHP ActiveRecord implementation -- Eloquent ORM. It can easily apply "constraints" to both sides of the relationship, so that you have complete control over the data and enjoy all the conveniences of ActiveRecord. Eloquent natively supports all methods of the query builder (query-builder) in Fluent. <?php namespace Illuminate\Tests\Support; use stdClass; use ArrayAccess; use Mockery as m; use ReflectionClass; use JsonSerializable; use PHPUnit\Framework\TestCase; use Illuminate\Support\Collection; use Illuminate\Contracts\Support\Jsonable; use Illuminate\Contracts\Support\Arrayable; class SupportCollectionTest extends TestCase {     public function testFirstReturnsFirstItemInCollection()     {         $c = new Collection(['foo', 'bar']);         $this->assertEquals('foo', $c->first());     }

Its implementation process is as followsUPLOAD the file to the temporary directory?>Use move_uploadde_file() to the specified directoryThis is the PHP upload process, or you can perform some verification in the middle. For example, determine whether the document is submitted through upload, or whether the file extension is allowed by us

Hypertext Markup Language is an application under the Standard Universal Markup Language. It is also a specification and a standard. It uses markup symbols to mark various parts of the web page to be displayed. The web page file itself is a text file. By adding tags to the text file, you can tell the browser how to display the content (such as how to process text, how to arrange pictures, how to display pictures, etc.). The browser reads the web page files in order, and then interprets and displays the marked content according to the tags. The error will not be pointed out for wrongly written tags, and the interpretation and execution process will not be stopped. The compiler can only analyze the cause of the error through the display effect. and error location. However, it should be noted that different browsers may have different interpretations of the same tag, and thus may have different display effects.

Generally recorded as s=“a1a2···an” (n>=0). It is a data type that represents text in programming languages. In programming, a string is a continuous sequence of symbols or values, such as a symbol string (a string of characters) or a binary digit string (a string of binary digits). Usually the entire string is used as the operation object, such as: finding a substring in the string, obtaining a substring, inserting a substring at a certain position in the string, deleting a substring, etc. The necessary and sufficient conditions for two strings to be equal are: the lengths are equal, and the characters at each corresponding position are equal. Assume that p and q are two strings. The operation of finding the position where q first appears in p is called pattern matching. The two most basic storage methods of strings are sequential storage and linked storage.

It is a very easy-to-use and convenient form data validation class<?php //验证类 class Fun{         function isEmpty($val)   {     if (!is_string($val)) return false; //是否是字符串类型        if (empty($val)) return false; //是否已设定        if ($val=='') return false; //是否为空     return true;          }
