thinkphp 分表 partition
我预设了10个表 分别是 table_1、table_2、table_3....table_10在Model中设置了partition:
protected $partition = array(
'field' => 'id',
'type' => 'id',
'expr' => '',
'num' => 10,
);
也使用了getPartitionTableName()
官方文档说是必须传入当前的数据。然后根据数据分析应该实际操作哪个数据表
而这个传入当前数据是什么数据,, 我每次实验的结果都是联合查询!不能找到当前表名!
请高手帮帮忙!或者有什么合适的方法!
回复讨论(解决方案)
你的分表字段是 id
所以在传给 getPartitionTableName 的数据数组中必须含有关联键为 id 的元素
不过他的算法有点怪异
$field = $data[$this->partition['field']]; switch($this->partition['type']) { case 'id': // 按照id范围分表 $step = $this->partition['expr']; $seq = floor($field / $step)+1; break;......... return $this->getTableName().'_'.$seq;按照你的设置,似乎应是 'type' => 'mod'
case 'mod': // 按照id的模数分表 $seq = ($field % $this->partition['num'])+1; break;

怎么没看到数据达到多少条之后将会写入第二张表中之类的,CURD的时候怎么处理~~~
你用 getPartitionTableName 取得的不就是表名吗?
有了表名不就和不分表时一样操作了吗?

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
