怎么让数组中多个成员,匹配MYSQL单字段里的一篇文章
如何让数组中多个成员,匹配MYSQL单字段里的一篇文章。
例如
数组:
$arr=array('tom','cat','jam','tim','bim');
mysql 中的 文章字段 内容如下
第一条字符串
tom,cat,tony,girl
第二条字符串
jam,tim,bim
第三条字符串
jam,tom
第四条字符串
tool,wood,boy,cat
通过这个数组怎么把下面四条全部匹配出来
------解决思路----------------------
$sql = 'create temporary table T ';<br />foreach($arr as $i=>$v) {<br /> $sql .= $i ? "union select '$v' " : "select '$v as name ";<br />}<br />mysql_query($sql); //创建临时表<br /><br />$sql = "select * from tbl_name, T where find_in_set(T.name, tbl_name.field)";<br />$rs = mysql_query($sql); //查询<br />
------解决思路----------------------
如果查询的比较多用全文搜索,最直接且很快,
再者你的词有逗号分隔,那么分词就特别容易了。
------解决思路----------------------
把下面的字符串变成数组,与上面的数组比较,如果数组有相同元素,就把当前字符串记录下来。

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

The main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.

SQL is a standard language for managing relational databases, while MySQL is a database management system that uses SQL. SQL defines ways to interact with a database, including CRUD operations, while MySQL implements the SQL standard and provides additional features such as stored procedures and triggers.

MySQL and phpMyAdmin can be effectively managed through the following steps: 1. Create and delete database: Just click in phpMyAdmin to complete. 2. Manage tables: You can create tables, modify structures, and add indexes. 3. Data operation: Supports inserting, updating, deleting data and executing SQL queries. 4. Import and export data: Supports SQL, CSV, XML and other formats. 5. Optimization and monitoring: Use the OPTIMIZETABLE command to optimize tables and use query analyzers and monitoring tools to solve performance problems.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
