语法介绍:
phplib中常用的方法有set_file,set_block,set_var,parse,ppasre,p,get等。
声明:由于本系统采用的是phplib,如果页面中有大括号对,这将会替换成空白,所以在写此文章时,用"[[","]]"来替代大括号。大家在用的时候是用大括号便是,此处仅为写文章方便而作此约定。
set_file:是用来引入模板文件。
用法:
$t->set_file("show_main","main.htm");
或
$t->set_file(array(
"show_header"=>"header.htm",
"show_main"=>"main.htm"
));
set_block:用来声明一个区块
用法:
$t->set_block("show_main","rowlist","RL");
稍微解释一下,show_main是用set_file取得的文件句柄,rowlist是模板页面中的区域标识一般如下方式来写
[[param]] |
如上是将
区块是可以嵌套的
[[param]] |
如上所示,这声明一个嵌套区块,这在boeiBlog的像册部分采用了这种方式,有兴趣的朋友可以找出来看看
对于嵌套的模板,我们可以这样来使用
$t->set_block("show_main","rowlist","RL"); // 里面的参数从前向后依次是包含的关系,最后一个是别名,主要用来区块识别
$t->set_block("rowlist","collist","CL"); // 第一个参数是外层块的名称,第二个是自己的名乐,第三个是别名
循环这样的区块时要特别注意
如下:
$t->set_block("show_main","rowlist","RL");
$t->set_block("rowlist","collist","CL");
for($i=0;$i {
$t->set("CL");// 这里要对追加的列循环执行一次清理,否则会多出一堆东西
for($ii=0;$ii {
$t->set_var("param","boeiBlog");
$t->parse("CL","collist",true);// true参数表明这是追加
}
$t->parse("RL","rowlist",true);// 这里的true也是表追加
}
上述代码将会产生一个5X5的表格,每个单元格里会出现一个boeiBlog
set_var:用来作变量替换
上述代码里的$t->set_var("param","boeiBlog");就是把模板中的param变量替换成boeiBlog这个字符串,当然也可以替换成变量,如:
$curdate = date("Y-m-d");
$t->set_var("param",$curdate);
set_var也有追加属性,如:
$curdate = date("Y-m-d");
for($i=0;$i {
$t->set_var("param","
".$curdate,true);
}
这将产生十个连续的当前日期
有时候可以用set_var的追加属性来替代block的循环.
set_var是可以用数组的,如:
$t->set_var(array(
"param"=>"boeiBlog",
"title"=>"柏艾网络"
));
模板如下:
[[param]],[[title]] |
parse:用于解析文件
当我们将模板中的所有变量都处理完之后,可以用parse一将这个模板进行解析。这是模板处理的最后几道工序。
如:
$t->set_file("show_index","index.htm");
$t->set_file("show_main","main.htm");
$t->set_var("param","boeiBlog");
$t->parse("main","show_main");
我们所用的模板可能是:
main.htm
[[param]] |
如果此时还有另外一个模板,其结构如下:
index.htm
[[main]]
那么上述代码将会把main.htm中的变量替换成boeiBlog后再放到index.htm中的main处,最后形成一个在标签中的表格
解析完成之后便是输出页面,
p:用于输出页面
如:
$t->set_file("show_index","index.htm");
$t->set_file("show_main","main.htm");
$t->set_var("param","boeiBlog");
$t->parse("main","show_main");
$t->parse("index","show_index");
$t->p("index");// 此处便会将整个index页面输出,注意main.htm已经被嵌入到index.htm,所以不用$t->p("main");
pparse:同p一样也用来输出页面
如:
上述代码可以如下简化
$t->set_file("show_index","index.htm");
$t->set_file("show_main","main.htm");
$t->set_var("param","boeiBlog");
$t->parse("main","show_main");
$t->pparse("index","show_index");// 此处将p和parse结合到一起,立即完成解析并输出
get:用于获得文件内容
如:
$t->set_file("show_index","index.htm");
$t->set_file("show_main","main.htm");
$t->set_var("param","boeiBlog");
$t->parse("main","show_main");
$t->parse("index","show_index");
$getstr = $t->get("index");
echo $getstr;// 你将会看到这实际上和p是一样的。
利用get,我们可以轻松的取得生成页面的内容,这可以用于静态页面的生成。可以看到phplib用来处理静态页面是非常方便的 bitsCN.com

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

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.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
