Integration of PHP and database storage management
May 17, 2023 pm 08:31 PMWith the development of the Internet, the business of modern enterprises has become increasingly dependent on computer support and management, and the importance of databases has become increasingly prominent. In this case, both enterprises and programmers inevitably need to use technical means of data storage management.
As one of the most widely used scripting languages ??on the Internet, PHP language has also attracted much attention for its application in database storage management. This article will focus on the integration of PHP and database storage management, analyzing its advantages and practical methods.
1. PHP language and database
As a server-side scripting language, PHP language has excellent web page production capabilities and is widely used in practical applications. At the same time, PHP also has a wealth of extension libraries and plug-ins, making it cross-platform and easy to use.
Corresponding to this is the database system, which is a container for data and can store, retrieve and manage large amounts of data. It is an important data storage tool in enterprise business.
In PHP, we can connect to the database and manipulate the data in it through database management interfaces (such as PDO and MySQLi). Among them, PDO (PHP Data Objects) is a "database neutral" API that can support a variety of databases, such as MySQL, SQLite, Oracle, etc.; while MySQLi is an API designed for MySQL and is used to interact with the MySQL database.
2. Advantages of integrating PHP with database
- Database driver
PHP’s PDO extension is a database driver. It can be easily switched between various databases with only minor adjustments. In other words, the code is more portable.
- Security
PHP’s PDO and MySQLi extensions can handle all data types and provide a secure data filtering mechanism that can prevent some SQL injection attacks. They all provide a prepared statement mechanism (Prepared Statement). When writing a prepared statement, you can use "?" instead of parameter binding.
- Code cross-platform
Because PHP is a cross-platform language, it can be easily used on any system. This also ensures the portability of the code, and the same code can be used on different operating systems without having to worry about code compatibility issues.
- Processing large amounts of data
PHP language can handle large amounts of data, including concurrent access, reading and writing across servers, and during all processing, PHP saves the memory There is very little pressure.
- Execute stored procedures and functions
MySQL stored procedures and functions are very important in optimizing database performance and reducing code complexity. PHP can be used to directly call and execute MySQL stored procedures and functions, thereby improving developer productivity.
3. PHP and database practical methods
There are several practical methods when writing a website based on PHP and database.
- Use PDO or MySQLi extension
PDO and MySQLi are commonly used database extension libraries in PHP and are widely used in scenarios of interacting with databases. The APIs of these two extension libraries are very similar, and they are both developed based on object-oriented mechanisms, so there will be no significant performance difference using either of them. At the same time, since they all use error codes to handle errors, these errors are very useful to developers.
- Using Frameworks
Using popular PHP frameworks such as Laravel or Symfony can significantly increase developer productivity. They provide many components and plugins that speed up writing code and make it easier to manage.
These frameworks also include ORM (Object Relational Mapper), which allows developers to map database data onto objects for easier consumption. Common operations like creating and dropping tables, adding/removing columns, and establishing relationships are also apparently easy.
- Database Optimization
Using the correct indexes, partitions, threads, caches, etc., can significantly improve database performance. Similarly, using stored procedures and views can encapsulate query or update data operations, reducing the corresponding complexity and code length.
Conclusion
In enterprise business, the importance of database storage management technology is self-evident. PHP language is a relatively widely used programming language, and its excellent extension libraries and plug-ins also provide good support for database storage management. In order to achieve high-quality code and efficient data access, programmers need to make full use of PHP and database systems to integrate technical means to create the best quality.

The method to get the current session ID in PHP is to use the session_id() function, but you must call session_start() to successfully obtain it. 1. Call session_start() to start the session; 2. Use session_id() to read the session ID and output a string similar to abc123def456ghi789; 3. If the return is empty, check whether session_start() is missing, whether the user accesses for the first time, or whether the session is destroyed; 4. The session ID can be used for logging, security verification and cross-request communication, but security needs to be paid attention to. Make sure that the session is correctly enabled and the ID can be obtained successfully.

To extract substrings from PHP strings, you can use the substr() function, which is syntax substr(string$string,int$start,?int$length=null), and if the length is not specified, it will be intercepted to the end; when processing multi-byte characters such as Chinese, you should use the mb_substr() function to avoid garbled code; if you need to intercept the string according to a specific separator, you can use exploit() or combine strpos() and substr() to implement it, such as extracting file name extensions or domain names.

In PHP, the most common method is to split the string into an array using the exploit() function. This function divides the string into multiple parts through the specified delimiter and returns an array. The syntax is exploit(separator, string, limit), where separator is the separator, string is the original string, and limit is an optional parameter to control the maximum number of segments. For example $str="apple,banana,orange";$arr=explode(",",$str); The result is ["apple","bana

JavaScript data types are divided into primitive types and reference types. Primitive types include string, number, boolean, null, undefined, and symbol. The values are immutable and copies are copied when assigning values, so they do not affect each other; reference types such as objects, arrays and functions store memory addresses, and variables pointing to the same object will affect each other. Typeof and instanceof can be used to determine types, but pay attention to the historical issues of typeofnull. Understanding these two types of differences can help write more stable and reliable code.

std::chrono is used in C to process time, including obtaining the current time, measuring execution time, operation time point and duration, and formatting analysis time. 1. Use std::chrono::system_clock::now() to obtain the current time, which can be converted into a readable string, but the system clock may not be monotonous; 2. Use std::chrono::steady_clock to measure the execution time to ensure monotony, and convert it into milliseconds, seconds and other units through duration_cast; 3. Time point (time_point) and duration (duration) can be interoperable, but attention should be paid to unit compatibility and clock epoch (epoch)

In PHP, to pass a session variable to another page, the key is to start the session correctly and use the same $_SESSION key name. 1. Before using session variables for each page, it must be called session_start() and placed in the front of the script; 2. Set session variables such as $_SESSION['username']='JohnDoe' on the first page; 3. After calling session_start() on another page, access the variables through the same key name; 4. Make sure that session_start() is called on each page, avoid outputting content in advance, and check that the session storage path on the server is writable; 5. Use ses
